DateQuestionAnswer
2014-07-18 14:00:00 (link to chat)When does Trevor Rosenthal become a starter, and does he have enough of an arsenal to last 6-8 innings a game?
(Randall from Mizzore)
Don't think imminently, though I think the arsenal is fine for a starting role. The control this year is crazy. I'll just go ahead and predict a TJ in the next 12 months, cause life sucks. (Sam Miller)
2014-06-26 14:00:00 (link to chat)I'm in a league that is "dynasty" by default (16-keepers, keep-forever) in which most of the other managers play as if it is a redraft league. Given that, if I offered Oscar Taveras for Trevor Rosenthal, it would be refused. Crazy, right?
(RatedRookie from Atlanta)
This makes me sad. However, it also means you should be able to clean up in a couple years. (J.P. Breen)
2014-05-29 19:30:00 (link to chat)You recently ranked Carlos Martinez 70th in the U25 dynasty rankings. Curious about your logic, confidence in that rank, and maybe expected trend? He seems stuck (destined to stay?) in setup purgatory. Is there a light at the end of the tunnel? If you could acquire him sorta cheaply, would you be excited about owning him in 2015, 2016, beyond?
(AY from DC)
I don't think he stays in the bullpen forever, he's just too talented. Maybe the Cards use him as the centerpiece in a deal to land an elite bat. Maybe they make room for him in the rotation. But you just can't leave that arm in the 'pen, especially if you've already forced Trevor Rosenthal to share that same fate. (Ben Carsley)
2014-05-20 13:00:00 (link to chat)What's wrong with Trevor Rosenthal?
(Kingpin from Grinnell, IA)
he's walking a lot of guys, isn't he. So that hints at some issues with fastball command, but I'm also suspicious of his changeup. He's throwing it in the zone a lot (54% vs 24% in 2013) and, as a result, missing far fewer bats (.38 whiff, good, but not the .49 epic whiff of 2013). All told he's given up more fly balls, missing fewer bats and missing with his fastball and changeup. (Harry Pavlidis)
2014-05-21 13:00:00 (link to chat)Is it time to start panicking about Trevor Rosenthal?
(AJ from Phoenix)
A bit, yes. He was my pick to take over the top of the closer heap, but I'm quite bummed by his control issues. Matheny's usage doesn't help... four straight days?! I'm all for using RPs more, but rather long outings than more frequent ones. (Paul Sporer)
2014-03-14 09:00:00 (link to chat)If I roster both Yordano Ventura and Carlos Martinez, what will I have at the end of the season? Two gasoline-throwing RPs? Or two top-50 SPs? Or something in between?
(RatedRookie from Atlanta)
You'll probably have something in the middle in Ventura's case. I think he'll come up later in the year, show flashes of brilliance but offer outings that are maddeningly frustrating. Martinez will likely stay in the pen, but events in St. Louis could prove me wrong. I think he'll be an amazing set up to Trevor Rosenthal, and could provide the Cardinals with the best 1-2 postseason punch since Mariano Rivera and John Wetteland in 1996. (Mike Gianella)
2014-02-10 13:00:00 (link to chat)Do you think teams are too quick to banish hard throwing pitchers with possibly starting repitores to the bullpen? Especially because very few guys that go into the bullpen are given a chance to start. For example Trevor Rosenthal comes to mind. He is banished to close while Wacha or Joe Kelly get to start.
(Gila Monster from Boston)
Some teams, maybe, but in the case of the Cardinals and Rosenthal, I think it was a matter of necessity and depth. In almost any other organization, he'd probably still be starting, or at least would have had more of a chance to fail at it. The Cardinals simply didn't need to wait for that. He was more valuable to them closing games and they have plenty of other guys who could start. It's a nice problem to have. (Jeff Moore)
2013-12-20 14:00:00 (link to chat)Do you think we'll see Trevor Rosenthal starting for the Cards by 2015, or is he going to turn into another Papelbon "they needed a closer" story?
(dianagram from VORGville)
I would love to see Rosenthal in the rotation, but teams are so reluctant to move a guy who has had that level of success that I fear that he may be stuck in the role. His best shot to start might actually be to get lit out of the pen for a couple of months, but he's in the wrong organization to wait for an opening in the rotation. There is a glimmer of hope in the form of Adam Wainwright, who closed for the Cards for a short stint in 2006, but he was quickly moved to the rotation. In that sense, 2014 could be a do or die season for Rosenthal's future role, as another successful season of relief might get him stuck in the 'pen.

On the jukebox: Drist, "The Scalpel" (Doug Thorburn)
2013-10-28 18:00:00 (link to chat)Hi Mike, From a fantasy perspective keep 2 of the following: Chris Archer, Trevor Rosenthal, and Danny Salazar
(JasonPennini from Denver)
Hi Jason.

Tough question to answer without knowing what Rosenthal's role is going to be next year. Assuming he is closing, I would go with Archer and Rosenthal. Salazar is an exciting talent, but given the limitations on his pitch counts this year, I'm less confident in him in what will be his first full season. I always lean toward Rays pitchers given the organization's strong track record, and it's not like Archer struggled in his rookie campaign either. Take Archer and go with Rosenthal in the hopes that he's closing. If he isn't closing, he's the rare middle reliever who - even in a standard mixed league - will have some value. (Mike Gianella)
2013-10-28 18:00:00 (link to chat)Hi Mike. Why hasn't Shelby Miller pitched this off-season? Obviously Mike Matheny has lots of options at his disposal but is there something specific going on with Miller such as a hidden injury or an attitude problem?
(mmcduffe from Ottawa)
I don't have the answer, but I've heard a few theories. One theory is that Miller is gassed, and his 12% strikeout rate in September is a sign of this. Miller has become the in-case-of-emergency-break glass guy. Matheny's use of his pen has been a bit of a mystery to me. I get that he has Carlos Martinez and Trevor Rosenthal as a very strong 1-2 punch, but there have been games where he seems to be going to the well with lesser relievers. Miller and Edward Mujica don't seem to belong on the roster, and Matheny's non-usage of them is a little odd. (Mike Gianella)
2013-11-05 13:00:00 (link to chat)Seems like there are a number of older "proven closers" on the free agent market with only a handful of opportunities out there- Joaquin Benoit, Grant Balfour, Joe Nathan, Fernando Rodney, Edward Mujica not to mention the injury reclamation projects like Brian Wilson, Ryan Madson and Joel Hanrahan. With the success that the Cardinals had moving Edward Mujica back two innings and then doing the same with Trevor Rosenthal and Carlos Martinez in the playoffs, are the days of spending big on closers finally over? Does a team like the Cubs with no great in house solution and a smart front office take advantage of the oversaturated market or pass on all those guys?
(Scott from LA)
We'll continue to see a wide variety of approaches to how teams handle the late innings. On the one hand there is certainly something to the idea that there are people who can close and people who can't. But you'd be hard pressed to get a closer enough innings in a season to justify paying big for them (unless, like the Yankees, Phillies, Red Sox, etc. you simply have the money to spend). St. Louis has such a glut of arms they have no reason to go outside the org, but for many teams there simply aren't good reasons to limit a young, high ceiling arm to a closer role. I imagine the Cubs will look for a reasonably priced arm that they think can handle the job, rather than committing more money over multiple years. (Nick J. Faleris)
2013-10-11 14:00:00 (link to chat)Do you think the Cardinals usage of Carlos Martinez in the playoffs is preparing him for the same transition that Trevor Rosenthal had this year or is this simply a matter of needs trumping development? Seeing how teams are only now becoming stricter about innings limits on young pitchers, how will 90 innings of high leverage relief be seen if Rosenthal or Martinez then transition to the starting rotation?
(Scott from LA)
I think that Rosenthal is better prepared to enter the rotation, as his mechanical baselines and repetition are more sound at this point. Car-Mart has a lot of work to do in order to hone his delivery, and until he does, it may not be ideal for him to be plying his trade in a big-league rotation. That said, I also don't want him to become pigeon-holed in the bullpen, because he has a future in the rotation if he makes the right adjustments. (Doug Thorburn)
2013-09-12 18:00:00 (link to chat)Some non-closer this year that are good bets to earn 20+ saves next year are _____?
(Joanah from Redwood)
Hi Joanah.

No non-closer is ever a good bet to earn 20+ saves. If you had Kevin Gregg with 30 saves this year, raise your hand. Not so fast, every single one of you.

But if you're asking for names, I like Cody Allen in Cleveland, Ryan Cook in Oakland, and Trevor Rosenthal in St. Louis if he stays in the bullpen. All three are risks, but that's the nature of a question like this; these are all guesses at this point. I think the Indians will non-tender Perez, but maybe they sign him for $9-10 million. Grant Balfour probably leaves for free agency, but maybe he doesn't. Edward Mujica probably leaves, but maybe the Cardinals keep him or maybe Jason Motte is healthy and gets the role back. I used to shy away from the skills over roles thing, but now I believe it. If you grabbed Rosenthal in your fantasy league this year, you probably were very satisfied with the overall numbers (and especially the strikeouts) even though he never wound up closing. (Mike Gianella)
2013-09-26 13:00:00 (link to chat)Looking for saves in 2014, how many of these guys are capable/likely to grab 20+ saves next season: Trevor Rosenthal, David Robertson, Cody Allen, Jake McGee, Brian Wilson, Luke Gregerson, Pedro Strop, Drew Storen, Ryan Cook, Carlos Martinez, Vic Black, Joakim Soria, Neftali Feliz, Steve Delebar, Kelvin Herrera, Carter Capps, and/or AJ Ramos?
(J-Qwellin from Deplorable Future Leaders of America Club)
J-QWELLIN!!!! Interestingly enough, I'm working on such a piece re: 2014 closers. From your group, I'd go Rosy & D-Rob, but honestly any of them have the capability. I know that's a little copout-y, but that's the nature of the beast with relievers. (Paul Sporer)
2013-09-11 13:00:00 (link to chat)How would you slot all of the Cardinals young arms for next year? Who goes to the rotation besides Michael Wacha? Do Trevor Rosenthal and Carlos Martinez end up in the bullpen? Trade Joe Kelly?
(Scott from LA)
The Cardinals have so many first-world problems. Wacha is the most obvious one for the rotation, I think. Then Martinez. It will all depend on who is healthy. The Cardinals haven't had a healthy rotation all season and they're still having trouble finding room for Wacha and Martinez. I do think both of them are starters, but there's really no doubt with Wacha. He's probably a no. 4 starter at present and should end up as a no. 3. (Jason Cole)
2013-06-20 13:00:00 (link to chat)Paul, please list a few pitchers that could have that Kris Medlen like run in the 2nd half. And maybe some bullpen arms that if they move into a starting role, could have real value in mixed leagues. Oh and hello Curtis!
(andtinez from Houston)
Franklin Morales (Rubby or Webster, too, but neither is currently in their pen) and Tony Cingrani (obv, but he fits the model now) are currently in pens. Guys who could just make a big run who aren't currently in a rotation: Erasmo Ramirez, Trevor Rosenthal (prob more 2014 if he's gonna be an SP again), Alex Colome, and Tim Stauffer. http://pauls.files.wordpress.com/2013/06/hiandrew.jpg (Paul Sporer)
2013-05-28 13:00:00 (link to chat)Any reason to think Trevor Rosenthal would not succeed as starting pitcher if the Cards decided to stretch him out next spring?
(R.J. from San Diego)
I mean, I can think of one big reason if you were worried about what major league hitters would do to a guy whose main attribute is velocity and who now needs to pitch with less of it. So I don't think he'd keep up any of the same whiff rates or strikeout rates or anything, but he could fit in. The luxury the Cardinals have is so much young starting pitching that they should be able to make that decision not in a vacuum but with consideration to where everybody else fits in. (Zachary Levine)
2013-05-16 13:00:00 (link to chat)Do you think the Cardinals leave both Carlos Martinez and Trevor Rosenthal in the bullpen next season or do they find a way to start them?
(nubber from tx)
If you put both of those guys in the 'pen, you shrink the game. That's just nasty. Those guys are nasty. (Jason Parks)
2013-04-25 12:30:00 (link to chat)With the sky high expectations, who do you see as being the answer to the St Louis closing situation long term?
(Scott from LA)
I don't know whether you mean long term as in "the rest of this season" or long term as in "for years to come," but either way, I'd probably say Trevor Rosenthal is the likeliest candidate. Not that he couldn't be a successful starter, but Shelby Miller looks great in that role already, and it can be hard for managers to unlearn what they've learned when they see a young pitcher dominate out of the bullpen. (Ben Lindbergh)
2013-04-16 20:00:00 (link to chat)What's your take on Michael Wacha? Mid-rotation (in real life) SP?
(IrishPhog from StL)
Cosigned. Think he'll be in the Cards pen during the 2nd half and then groomed for the rotation eventually, a la Trevor Rosenthal. (Bret Sayre)
2013-04-10 20:00:00 (link to chat)Hello, a fantasy baseball trade question for ya. I was offered Trevor Cahill for Trevor Rosenthal. Both are cheap, so both could be keepers and I need SP help but Rosenthal could be a 40 save stud this year. Thoughts? Thanks
(tony from Minnesota)
Hi Tony.

Cahill is definitely a steadier/more reliable producer but Rosenthal definitely is more talented/has a higher ceiling, particularly for fantasy/Roto. For this year, I like Cahill better because I'm more certain of his role, but in the long term I like Rosenthal. I think this trade's OK to make if you need a starter, but given the keeper dynamic of some leagues I could also see holding on and trying to do better for Rosenthal later. My instinct tells me not to pull the trigger...even though Rosenthal might not close this year. (Mike Gianella)
2013-04-10 20:00:00 (link to chat)So, who do you have finishing the season with the most saves for the Cubs, Cards and Brewers? thanks
(Kevin from Boston)
For the Cubs, I would have to guess Kyuji Fujikawa. Carlos Marmol might get the job again, but he would probably be put in there to showcase him for a trade. Trevor Rosenthal isn't the closer now in St. Louis, but Mitchell Boggs has already struggled so if I'm going to guess, I'm going to guess the guy with the skills and the stuff. Milwaukee is a mystery to me. I thought John Axford would lose the job but had no idea it would happen so quickly. I would guess Jim Henderson, but he has some of the same control/command issues that Ax does/did. My sleeper in this pen is Brandon Kintzler, but I don't see Kintzler as having a path to the job at the moment. (Mike Gianella)
2013-04-18 14:00:00 (link to chat)Do you think Trevor Rosenthal eventually takes over the 9th inning or is Mujica good enough to hold it?
(nubber from tx)
I think that between Rosenthal's early struggles and his own ability, Mujica can retain the job for a long time. With Mujica, you can be confident that he won't suffer a three-walk meltdown, and he has proven effective against both lefties and righties throughout his career. He might not have the strikeout rates you'd typically associate with a dominant closer, but he's definitely an adequate option. (Daniel Rathman)
2013-03-27 20:00:00 (link to chat)Who are setup guys you could see taking over the 9th this season? Do you think Trevor Rosenthal is a smart stash or do you think Boggs does fine?
(Thad from Peoria)
Fujikawa, Benoit and Rosenthal are the top three I've been targeting. And yes, I really like Rosenthal as a stash, he could be a potential dominant bullpen arm and I think they'll go to him eventually if the injury to Motte ends up being particularly serious. (Bret Sayre)
2013-03-20 11:00:00 (link to chat)Another top fantasy writer, Eric Karabell thinks that Trevor Rosenthal may end up as the 8th inning guy this year and then becomes a starter next year, ala Adam Wainwright next year. Your thoughts? I've thought about taking him late in a keeper league.
(Eric from CO)
Eric knows his stuff and I wouldn't rule that out. Rosenthal has a big-time arm and even if he's not Shelby Miller, he's a pretty good prospect in his own right, too. That path makes sense, given the makeup of the Cards' staff this year. (Cory Schwartz)
2013-03-12 13:00:00 (link to chat)Trevor Rosenthal.Long termer reliever or starter ?
(Spirou from Montreal)
I want so badly to say starter bc I'm such a huge fan. We'll see how this year goes. If he can pull some spot starts, I'll be heartened that they might Lance Lynn him next year. If he is a long term reliever, he succeeds Motte in 2015. (Paul Sporer)
2013-02-27 20:00:00 (link to chat)Any of these guys worth a look in an NL only 4x4 standard league? Trevor Rosenthal, Tony Cingrani, Arodys Vizcaino, Christian Garcia, J.J. Hoover, or Sam Lecure.
(Johnny T from The Hills)
Rosenthal is definitely worth a $2-3 bid in NL-only. His stuff is legitimate and even if he's only a set-up man, his Ks mean that he could put up sneaky $10-12 value. (Mike Gianella)
2013-02-15 12:00:00 (link to chat)Mr. Collette, who would you add to this list of the best relief pitching options (no closers) for ratios: Kenlay Jansen, Trevor Rosenthal and Kyuji Fujikawa.
(RP producers from USA)
Jake McGee, Luke Gregerson, Mark Melancon (Jason Collette)
2013-02-15 12:00:00 (link to chat)Is Trevor Rosenthal a career starter or reliever? short-term?
(Max from Queens)
I want him in the rotation, he has the stuff to do it. (Jason Collette)
2013-02-22 13:00:00 (link to chat)Dynasty points league in its 14th year. I'm regularly competitive. I was likely to lose Greinke in free agency at the end of the year, and moved him for a prospect package of Trevor Rosenthal, Fried, Vogelbach, Quinn, and A. Mondesi. Would you have done it or kept Greinke and gambled that the flag would fly forever?
(doog7642 from Blaine, MN)
You did well (Sam Miller)
2013-02-19 13:00:00 (link to chat)Where does Trevor Rosenthal's future lie, in both the short term and long-term... the rotation or the bullpen?
(Jefferey Loria from Atlanta Renegadin')
In the short term, bullpen, I think--I'd expect Shelby Miller to lock up a rotation spot, which wouldn't really leave room for Rosenthal unless Garcia can't go. In the long term, I think he's certainly capable of starting, and probably will, but he might look so dominant in relief (as he did last October) that Matheny gets used to the idea of having him there and grooms him as Motte's successor. (Ben Lindbergh)
2013-02-14 13:00:00 (link to chat)What's Trevor Rosenthal's ultimate role, starter or reliever?
(Francois from Toronto)
Ultimate is starter. Could be Medlen-esque in 2013 (though maybe not with one of the greatest 12-start stretches ever, I just mean relieving for the first half and then starting & excelling). (Paul Sporer)
2013-02-14 13:00:00 (link to chat)In one of my leagues I have serious interest coming in for my Trevor Bauer. The best offer would consist of something like Bauer and a mid-late first round pick in the prospect draft (14th or 17th) for the 5th overall pick in the prospect draft and either Anthony Rendon or Trevor Rosenthal. Thoughts on fairness of those offers?
(Slevin from Brooklyn)
Tempting. I like both Bauer & Rosy quite a bit. I think the offer is very fair and I'd take Rosy in that scenario. (Paul Sporer)
2013-02-05 13:00:00 (link to chat)What do you expect Trevor Rosenthal's role to be for the Cardinals this year?
(Jason Pennini from Denver, CO)
I think he will pitch in a late-inning capacity and I think he will be awesome. (Jason Parks)
2013-01-22 13:00:00 (link to chat)How do you feel the Cardinals rotation shakes out? At what point for Shelby Miller and Trevor Rosenthal get their chance?
(Tommy from Btown)
It comes down to whether the Cardinals re-sign Lohse (doubtful by all accounts), Jaime Garcia's health, and their evaluation of Rosenthal as a starter. I think Rosenthal could spend the season in the pen, and I wouldn't be shocked if Miller is in the rotation come October. (R.J. Anderson)
2013-01-16 13:30:00 (link to chat)Mark, thanks for answering so many of my questions. Your insight is valued greatly.... Do you think Trevor Rosenthal finds a home in the STL rotation? Are they ready to let lohse go and insert rosenthal or does Shelby miller have the inside track there?
(Kai from SLO)
My pleasure, Kai. Thanks for coming out and asking so many questions!

I think Rosenthal could succeed in the Cardinals rotation but I'm not sure they are prepared to go that route. His dominance in the bullpen was ridiculous and extremely appealing. With other options like Shelby Miller -- who ultimately has a higher upside than Rosenthal -- they may be inclined to push Miller into that spot instead of Rosenthal. Honestly, I'd have a hard time faulting them for that. (Mark Anderson)
2012-12-13 13:00:00 (link to chat)Proposition: Trevor Rosenthal has passed Shelby Miller as the top pitching prospect in the ridiculously pitching-rich Cardinals farm system. Completely crazy, arguable but probably not, or likely to be true?
(Bill from New Mexico)
It's not completely crazy, but I disagree with the statement. I still prefer Miller because I think he's a safer bet to be a major league starter. (Jason Parks)
2012-12-13 13:00:00 (link to chat)A scout told a Fangraphs gentleman this year that he preferred Trevor Rosenthal to all the pitching prospects he'd seen in 2012, including Terrific Taijuan. Is Rosie's velocity and makeup so surpassing, or am I underestimating his secondary and tertiary offerings? Thanks, Perfesser!
(Fred Exley from Giant's Stadium above Hoffa's body)
No idea. I guess its just preference. Lots to like with Rosenthal, but he can't share that type of company in my opinion. (Jason Parks)
2012-11-29 13:00:00 (link to chat)I know there is little to no chance (and even that is an exaggeration) that Texas would trade Profar. But if the Cardinals would be willing to include Shelby Miller & Trevor Rosenthal, would that at least pique the Rangers’ interest?
(Kingpin from Grinnell, IA)
Thanks for the question, Kingpin. Guessing a lot of threes being hoisted in your gyms recently. I always think you should be willing to at least listen, because you never know what value the other club paces on your and their players. There are guys who you believe you would never consider moving, but a good professional relationship with the other side usually provides some element of reality. Keep in mind that about 90% of deals discussed never get to the finish line anyway. (Dan Evans)
2012-11-01 13:00:00 (link to chat)Hi again, Mr. Luhnow-for-a-day-elsewhere. Trading Tulo and CarGo is an interesting idea, but for what? Simply try to stockpile as many power arms as possible? (Example: Tulo for Trevor Rosenthal, keeping in mind Rafael Furcal's dubious health. Who hangs up first, and what throw-ins might make the trade work?)
(BillJohnson from New Mexico)
Not necessarily just pitchers -- stockpile as many legit future big-leaguers as possible. That's what I feel like Luhnow has done in HOU. If you know you can't compete for at least 3 years, sell off everything that has value now but won't in 3 years (or whatever your time horizon is). Get stuff back that will have value in 3 to 6 years (or whatever).

Tulo for Rosenthal straight up seems like a massive overpay for Rosenthal. (Ian Miller)
2012-10-23 13:00:00 (link to chat)What kind of ceiling does Trevor Rosenthal have?
(temple from madison, wi)
It's high. The arm strength is obvious, but the delivery is ultra-smooth and the arm works very well. His delivery is very Oswalt-like, which I enjoy very much. I think he can start, but I understand the allure of keeping him in the 'pen going forward. His arsenal isn't crazy deep, as he relies heavily on the FB. But he does know how to pitch, and I think he could develop into a #3 starter type. Of course, he could also pump near elite FB in short-bursts, which helps his secondary stuff play up and makes him a monster. He has closer's stuff, and based on the reports of his makeup, he also has the fortitude for high leverage. Interesting situation. The Cardinals are good at drafting. (Jason Parks)
2012-09-20 13:00:00 (link to chat)Thanks for the chat, Mr. Parks. Flamethrower Trevor Rosenthal...plausible #2 starter upside, or more like a 3/4?
(Cordwainer Bird from Hollywood)
Some of that raw stuff makes you dream of a #2 ceiling, and I know several scouts that would put him on a pedestal that high. I'm a bit more cautious with him because of the secs, but he looks like a very good arm. Cardinals have a lot of talent. (Jason Parks)
2012-09-20 13:00:00 (link to chat)More detail on Trevor Rosenthal? He looked absolutely filthy in some big league pen performances this year? Does he stay in the pen or does he have a future in the rotation?
(sean3258 from Coatesville, PA)
More value in a rotation; easier path for success in the bullpen. Glad its not my call. (Jason Parks)
2012-09-10 13:00:00 (link to chat)How high does Michael Wacha slot into the Cardinals' long list of pitching prospects? Presumably after Miller, but do you expect more of him than of Carlos Martinez or Trevor Rosenthal?
(Bill from New Mexico)
I'm still not sure where he fits into a rotation. I'll take Miller and Martinez over him, but probably Wacha over Rosenthal. (Bradley Ankrom)
2012-03-29 13:00:00 (link to chat)I know, it's spring training, don't read anything into results, etc., but has anything occurred this spring that catches your eye as suggesting an unexpected breakout about to happen? Example: Cardinals pitching prospect Trevor Rosenthal sat down with Chris Carpenter and learned Carp's cutter ... and then went out and blew 'em away in his next appearance. Would a young 3-star pitcher learning a new pitch like that be enough to move him into 4-star (or above) territory?
(Bill from New Mexico)
Don't get me wrong here, as I really like Rosenthal, and he COULD move into four-star territory, but are we really supposed to think that he sat down with Carpenter and by the next day had mastered a new pitch? (Kevin Goldstein)
2011-08-10 13:00:00 (link to chat)Trevor Rosenthal have a chance to be an elite closer?
(Johnson from IL)
No. (Jason Parks)
