BP Chats

DateQuestionAnswer
2017-08-16 13:00:00 (link to chat)Stephen Gonsalves and Jack Flaherty continue to tear it up in the minors. Do you see either receiving a September call up and making an impact at the major league level?
(Tap Dancer from There)
Gonsalves just got to Rochester, so I wouldn't expect his call up to be imminent unless he continues to dominate. It looks like he's well below his innings output from last season, so if they keep hanging around the WC race, he could be an interesting option.

I'd be more surprised if Flaherty gets a call this year, with their rotation looking a little more crowded and Luke Weaver likely being the next in line at the Triple-A level. (Mark Barry)
2017-06-13 12:00:00 (link to chat)What are scouts saying on Jack Flaherty's performance this season? What is his base-case scenario within a big league rotation? Thanks Craig! Love the articles
(Matt from North Carolina)
They're impressed. It's not a top of the rotation profile, but he could a No. 3 starter (if you believe in such a designation). He's got a full arsenal to work with, and I've heard arguments for him to be a top-50 type. (Craig Goldstein)
2017-01-06 13:00:00 (link to chat)Do you believe in Jack Flaherty as a long term prospect. Really up and down year last year.
(RDBL2014 from Concord, CA)
He's on our Cardinals list, going up next week, but the stock is down a bit. He doesn't have the largest margins for error. I think the system has gotten better around him as well. (Jeffrey Paternostro)
2017-01-06 13:00:00 (link to chat)Saw debate on a site about Jack Flaherty vs Luke Weaver. Said Weaver better short-term, but Flaherty higher ceiling and more likely to be starter long-term. thoughts??
(Donald T from the Towers)
Yeah, I can co-sign that. They are close enough for all that to be well within the fudge factor though. (Jeffrey Paternostro)
2016-09-08 19:00:00 (link to chat)Thanks for the chat George. Can you rank the following young SPs based on talent (exlcuding proximity to majors)? Trevor Clifton, Jack Flaherty, Jaime Schultz, Touki Toussaint. Can I also get your thoughts on the good Basabe brother, and how he compares to other good young OFs (e.g. Acuna, Whitley, Sierra, Mieses, Robles)? GO SOX!
(Anthonyb from Boston)
You got it Anthony! This is a group of starters that I think will all end up in the bullpen, especially Schultz and Toussaint. If I had to pick one, I guess it would be Clifton. I haven't seen Basabe in-person yet, I'm planning on it once he reaches Double-A Portland (in my neck of the woods). The numbers are impressive and he seems like an incredible athlete that is starting to translate those skills into tangible on-field production. I put Robles and Acuna in a higher class than almost any prospect left in the minors. Those two are both top-10-to-15 fantasy prospects for me right now. (George Bissell)
2016-08-11 14:00:00 (link to chat)I missed out on or traded numerous prospects in my NL-only keeper league. Who are some under the radar guys (it's a 10-team league, large reserve list)? They need to have an ETA of 2018 at the latest as the three year clock starts running on them as soon as they are drafted.
(johnklein from east coast)
This is a tough question. Josh Hader is worth rostering in keeper leagues, despite the risky profile. I'm not sure what qualifies for "under-the-radar" in a 10-team league (as it depends on the size of the reserve list), but guys like Forrest Wall, Yusniel Diaz, Cody Ponce, and Jack Flaherty are guys I like. (J.P. Breen)
2016-06-17 13:00:00 (link to chat)Any thoughts on Jack Flaherty's uneven season so far? He is dominating now, wondering what the early issues may have been.
(RDBL2014 from Concord, Ca)
Flaherty got off to a poor start, but the issues were really concentrated in one disastrous outing, with a few so-so ones mixed in. Without having seen him or read a lot of eyewitness reports, the thing I've read about him on multiple occasions is that he lacks an offering that consistently grades out as plus. That can lead to trouble putting hitters away, particularly on days when the command isn't sharp, and stringing a few of those together gives you a slow start. It certainly looks like he's turned it around, though. (Daniel Rathman)
2015-09-09 13:00:00 (link to chat)Are you a believer in Reds' Cody Reed or Cardinals' Jack Flaherty?
(Ricardo from DFW)
Flaherty more than Reed. Flaherty has three above-average pitches and the command could be plus, he could be something. Reed has improved quite a bit, slider is routinely plus like it was coming out of the draft, so there's some upside there, too. I just think Flaherty offers more upside and safety. (Christopher Crawford)
2014-11-20 13:00:00 (link to chat)Have you had the pleasure of seeing Jack Flaherty pitch?
(Perry from Fort Mill, SC)
Absolutely. I'm based in Southern California and I saw him four times this spring after a few looks as an underclassman.

Interesting profile. Was a standout third base prospect as well, would flash power in BP but used an opposite field oriented contact approach in games. Not a big velocity guy, the highest I ever saw out of him was 92 and he generally sat 86-89. But he also threw well over 80% strikes, and more were quality strikes at that. He had the best command of any high school arm in the 2014 draft (and 2014 was one of the best years for HS arms in draft history). It wasn't just fastball command either, he had highly advanced feel for the slider as well, and he could drop his soft curveball in for called strikes (and to give hitters an additional pitch to worry about) and fool hitters with a solid changeup.

The ultimate ceiling comes down to how much he develops and realizes his projection. He won't ever need to be a mid 90s guy to be a successful starter, but if he gets there then we could be talking about a valuable asset. More likely he's a mid rotation innings eater, but there is some ceiling here and he's in a good player dev system. (Todd Gold)
2015-02-09 20:00:00 (link to chat)Hey Nick who was your favorite guy from the 2014 MLB draft that did not make the list?
(Mo from MN)
Touki Toussaint, Michael Chavis, Sean Reid-Foley, Jack Flaherty, Derek Fisher, Max Pentecost, Michael Kopech, Luis Ortiz, Forrest Wall. There's been a solid influx of low-minors talent. (Top 101 Chat)
2014-11-24 13:00:00 (link to chat)How many of your NL Central Top 25 do you expect to make it on the top 100 list when BP publishes it? Average would be around 16 or 17 assuming talent is evenly distributed, right?
(Mike from Texas)
I did say I'd throw a top 25 NL Central Prospects list out there during this chat. With the understanding this is a work in progress (Mellen and I are starting to dig in on the framework for the Top 101), this is my own personal ranking of the prospects covered in our NL Central rankings:

1. SS Addison Russell
2. 3B Kris Bryant
3. RHP Robert Stephenson
4. OF Jorge Soler
5. OF Albert Almora
6. OF Stephen Piscotty
7. LHP Marco Gonzales
8. RHP Tyler Glasnow
9. RHP Jameson Taillon
10. OF Jesse Winker
11. OF/1B Josh Bell
12. RHP Alex Reyes
13. C Kyle Schwarber
14. RHP Michael Lorenzen
15. SS Orlando Arcia
16. OF Tyrone Taylor
17. OF Billy McKinney
18. RHP Pierce Johnson
19. SS Gleyber Torres
20. RHP Jack Flaherty
21. OF Yorman Rodriguez
22. C Reese McGuire
23. RHP Nick Howard
24. RHP Devin Williams
25. LHP Rob Kaminsky

I think all of those guys will be in the discussion for the 101, and expect there to be some shuffling in order of course. Definitely more than the average of 16 or 17. (NL Central Top 10s With Nick Faleris)
2014-11-04 18:00:00 (link to chat)Can you give us a scouting report on Jack Flaherty? I recently saw some video and was impressed by his size, feel for his breaking ball, and his free and easy delivery.
(Jim from KC)
I haven't seen Flaherty in person, but what I'm hearing from industry folks and our internal team suggests he could be a guy that blows up a bit in 2015. What he lacks in experience, he makes up for with early feel for a broad arsenal and good athleticism. I think there's a lot to like here. (Mark Anderson)
