BP Chats

DateQuestionAnswer
2014-05-21 13:00:00 (link to chat)Scoresheet league here .Don't have a real closer.Alternating between David Carpenter,Jake McGee and Kelvin Herrera at this point.Based solely on E.R.A,who would you entrench as your closer the rest of way ?
(Spirou from Montreal)
Herrera for me (Paul Sporer)
2014-03-14 09:00:00 (link to chat)I'm in a league that has holds as a category. Who are 3 guys I can target?
(DServi4 from Maryland)
I never really recommend targeting pitchers specifically for holds. With non-closers, I'm an advocate for going for skills, not roles. If you are going to target holds, though, I would probably go with Brian Wilson, David Carpenter, and Kelvin Herrera. I like the idea of getting pitchers behind strong closers, since you reduce your risk of losing holds with a solid option in the stopper role. (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)
2013-02-27 20:00:00 (link to chat)Romo & Holland are amongst my keepers this season - do both keep their closer jobs all year?
(Mike from Chi-town)
I'd say yes to Sergio Romo in all likelihood... keeping in mind that the Giants aren't afraid to switch roles at the earliest sign of trouble. I think Greg Holland will be OK, but Kelvin Herrera is extremely talented. If you're a believer in the skills versus roles thing, Herrera's a guy you'll want to grab in deeper formats. (Mike Gianella)
2013-02-15 12:00:00 (link to chat)Are the chances good that Carter Capps and Kelvin Herrera can unseat Tom Wilhemsen and Greg Holland is the (primary) 9th inning option?
(Mateo from Reno)
I'd say more for injury than skills as I like both of those incumbents. (Jason Collette)
2012-12-18 13:00:00 (link to chat)Seattle and KC don't have a closer who has his gig locked down. I'm betting on Carter Capps in Seattle and Kelvin Herrera in Kansas City (unless Ventura is moved to the bullpen down the road). Smart money, or should I invest in someone else?
(Jonah from Brooklyn)
What's wrong with incumbents Wilhelmsen and Holland? You can speculate on those others on the cheap, but I'd still bet on the 2012 guys. (Paul Sporer)
2012-12-28 13:00:00 (link to chat)When will Kelvin Herrera supplant Holland for closing duties in KC?
(John from Kansas City)
Hi John. I'm guessing as soon as the Royals find a taker for Holland? It shouldn't be hard; he's a good pitcher. (Geoff Young)
2012-12-28 13:00:00 (link to chat)Kelvin Herrera in KC, Arodys Vizcaino in North Chicago, and Carter Capps in Seattle. Who has the best chance to lead their team in saves in 2013?* In 2014? (*I know Vizcaino is coming back from TJS).
(Kevin from Des Moines)
Thanks for the question, Kevin. Trying to guess save opportunities is a fool's errand, but I'll go with Herrera on the basis that he has the most big-league experience. (Geoff Young)
