BP Chats

DateQuestionAnswer
2017-04-28 13:30:00 (link to chat)Ok, so sorry about the quality of the players in this Q, but 15-team, 30 man roster... Thoughts on Nate Karns so far? Would you drop him for JC Ramirez, Miguel Gonzalez, Derek Holland, Matt Cain, Erasmo, Shields, Brett Anderson or Nolasco? What type of FAAB bid?
(Craij's brother from another mother from Sandwich, UK)		Yeah I'd dump Karns pretty easily. I'd probably opt for either Gonzalez or Nolasco, as tepid as those waters are. (Craig Goldstein)
2015-01-15 18:00:00 (link to chat)Do you prefer Alex Colome or Nate Karns or Burch Smith as a starter?
(Goseman from Detroit)		I'll take Colome out of that trio. (Mark Anderson)
2014-04-15 13:00:00 (link to chat)Is Nate Karns anything other than a back of the rotation or bullpen arm?
(Mark from IA)		Not for me, no. I think he's a bit of a swingman that can fill the back of a rotation on the right team. (Mark Anderson)
2014-03-04 13:00:00 (link to chat)Chris Archer working hard on change-up, Jake Odorizzi learning how to throw Alex Cobb's split-finger change-up, Nate Karns improving on his change-up and Jake McGee adding a change-up w/ a possibility of a curveball to his repertoire. Which one of these guys will benefit most from adding the pitch that some people are obsessed/fixated/fascinated with? If Odorizzi does indeed learn and hone "The Thing"(split-change), would this take him from a bottom-of-rotation to a 2/3 guy because he'll finally have an out-pitch?
(jlarsen from Chicagoland Area)		a killer changeup can move the needle, sure. But some times a guy is just hoping to get a half-way decent one. In theory any big league pitcher who 'learns awesome new pitch' is going to get better, change cutter knucklecurve etc, but it feels to me like Odorizzi and Archer are going to benefit the most, since they are already potential quality starters and this could put them over the top. Karns could be helped out by having a better chance to stick in the rotation, but that's not as shiny as having a chacne to be a front-line guy. (Harry Pavlidis)
2014-02-13 13:00:00 (link to chat)Nate Karns or Jesse Hahn?
(Danny from Boston)		Looks like the details of that Rays-Nats swap are coming in, so we've got a few Qs on that front.

This is a fun one because the Rays just traded Jesse Hahn (and Alex Torres) for Logan Forsythe and a grab bag of prospects a month ago, and now they've traded Jose Lobaton (and a grab bag of prospects) for Nick Karns.

Hahn and Karns are similar in a few senses: both were college arms, both have injury histories, both have two good pitches, and so on. Even their outlooks are a lot alike: possible MOR arm or impact bullpen guy. I guess it comes down to the medicals, and without knowing which is better, I'll just call them evenish. (R.J. Anderson)
2014-02-13 13:00:00 (link to chat)What do you think of the Nate Karns - Jose Lobaton deal? Seems like the Rays did better, but the Nats getting Felipe Rivero might help their case a bit
(Charlie from Bethesda, MD)		We covered this earlier in the chat but it's been a while so:

It seems like a fair deal. Lobaton was out of options and the Rays had two superior catchers they made multi-year commitments toward this winter. They obviously wanted Karns, but the Nationals didn't consider that a fair swap, so the Rays added two interesting, but limited parts to make it work. Both sides should be satisfied with the deal. (R.J. Anderson)
