BP Chats

DateQuestionAnswer
2013-04-16 20:00:00 (link to chat)How do I value Addison Reed if I just started a dynasty rebuild? I know closers should be the first thing to go in a rebuild, but I can't help but believe he's relatively stable and likely to help me when I compete again in 2-3 years. Thanks
(JoeTinker from Chicago)
Here is a list of all closers who recorded 25 or more saves in 2010: Brian Wilson (48), Heath Bell (47), Rafael Soriano (45), Joakim Soria (43), Matt Capps (42), Neftali Feliz (40), Francisco Cordero (40), Carlos Marmol (38), Billy Wagner (37), Jonathan Papelbon (37), Kevin Gregg (37), Mariano Rivera (33), David Aardsma (31), Juan Oviedo (30), Bobby Jenks (27), Ryan Franklin (27), Brad Lidge (27), Jose Valverde (26), Francisco Rodriguez (25) and Andrew Bailey (25). (Bret Sayre)
2011-08-04 13:00:00 (link to chat)What's scarier, today's stock market meltdown or Tim Wheeler's picture on MiLB.com?
(MJ from Madison, Wis.)
Aye caramba: http://web.minorleaguebaseball.com/milb/stats/stats.jsp?pos=LF&sid=milb&t=p_pbp&pid=572254

Still not as bad as Bobby Jenks' pic at ESPN or here. Cripes what a terrible beard. (Jay Jaffe)
2011-05-26 13:00:00 (link to chat)We already know Epstien is one of the best GMs in baseball. Can't argue with 2 rings in 10 years. What do you think of how his moves from last off season are panning out?
(Puppy-D from BAWSTON)
I was a bit stunned to see Sam Fuld still outhitting Carl Crawford a few days ago. I think he is pretty delighted to have Adrian Gonzalez on his squad, though, and eventually Crawford will turn it around. Now, if they can just get Bobby Jenks and Dan Wheeler healthy, the offseason could look about as good as it did in March. (R.J. Anderson)
2011-05-26 13:00:00 (link to chat)Bard seems to pitch well most of the time, but then will have some periods where he seems to lose his control or have problems with lefties. Can he take over from Paplebon as closer next year?
(Bruce from toronto)
Even if he's not, the Red Sox will still have Bobby Jenks sitting around. Also, I think most relievers go through stretches similar to Bard. (R.J. Anderson)
2010-12-07 13:00:00 (link to chat)Will Chris Sale begin in the bullpen to start the season?
(richardkr34 from St. Paul)
Considering they lost Putz and non-tendered Bobby Jenks, I would think so. He probably won't take the closer role right away, but he will definitely start the year in the pen. Ozzie still likes him as a reliever last I saw. (Marc Normandin)
2008-12-11 14:00:00 (link to chat)Thanks for taking the time for the chat. We all know there have been substantial talks with a couple of teams regarding Jermaine Dye, but is there any information on players like Bobby Jenks, Paul Konerko, and Jim Thome, who are all possibilities to be traded this offseason?
(Ben from Work)
It appears that the White Sox are going to hang on to Jenks now and there never seemed to be much of a market for Konerko and Thome, who both have no-trade clauses. (John Perrotto)
2008-01-14 13:00:00 (link to chat)Adam Loewen: Will the screw in his arm effect his longevity? Will it put him at risk for a by-product injury? Can he still have the power arm? Other than Cal Eldred, who else has pithced with a screw in his arm? How is he doing? Thanks.
(ButkusSayers from Chicago)
I could be wrong, but I think the screw was removed. There have been a couple pitchers who have had similar injuries -- Derrick Turnbow and Bobby Jenks come to mind -- and I think Loewen should come back pretty effectively. He's "on schedule" and should be throwing at the same pace with the other pitchers when the Orioles open camp. (Will Carroll)
2008-01-14 13:00:00 (link to chat)Will, as I ponder curveballs, I ask you : is there such a thing as really "clean" mechanics on a curve that won't build to injury? And if there are, is it possible to throw, say a Doc Gooden yakker or a Bobby Jenks curve with them?
(Justin Fox from New Jersey)
Yes, there are solid mechanical principles behind safely pitching a baseball, whether that's a curve or any other pitch. The difference is that in putting all of the pieces together, there's similar but different results. Think about it -- there's almost no two curve balls or sliders that are exactly alike. There's so much character in them, so much individuality, that it's a fun game to talk about. I recently watched a video of Gooden and was stunned that his curve looked more like a Zito "loop" than I remember early in his career; I'd remembered it as more of a Lincecum power curve that stayed low and "dropped off the table."

As for mechanics, yes, there are good, clean mechanics, but there's not "one true mechanic." (Will Carroll)
