DateQuestionAnswer
2010-03-17 14:00:00 (link to chat)How does the A's bullpen shake out? Also, if Chavez is healthy enough to start the season on the roster, is there any place for Fox?
(David from Alameda)
I think the big issue with the A's pen is that right now, it's almost as if everyone has one owie or another: Wuertz, Devine, Bailey, Breslow... it's the sort of nagging laundry list that Cedrick Bowers' or Jason Jennings' dreams are made of. So other than taking it for granted that most of those four will be available on Opening Day, and that Brad Ziegler's a lock, it's a bit up in the air. Henry Rodriguez's velocity turns heads. As for Fox, I wouldn't be too down on him. He's out of options, but I'd anticipate that part of keeping Chavez healthy would involve days off for him, and between the four corners and DH, there should be at-bats to go around. The guy who's playing for the present is Daric Barton, who's rising to the challenge, but he has to, because the future belongs to Chris Carter. (Christina Kahrl)
2008-02-29 13:00:00 (link to chat)Everyone seems to say that the Rangers "need more pitching", but is that truly the problem? I guess I've become used to the high offense environment of Rangers Ballpark so I think the problem is that their outfield hasn't produced in a while. Question: year too early? will they content before the A's?
(Ira from Texas)
Generally speaking when teams in hitter's parks do well, they do so based on their pitching. And so getting their rotation ironed out (a rebound from Jason Jennings would of course be among the biggest shots in the arm they could hope for).

That said, I kind of agree with you in that they certainly need more producion from their outfield. I just don't see Byrd, Catalanotto, Bradley, and Hamilton really getting it done. Their team EqA in 2007 was just .257 and that's got to improve if they're going to be competitive before the A's. (Dan Fox)
2008-01-17 14:00:00 (link to chat)Thoughts on the Rangers signing Jason Jennings to a one-year, $4 million deal?
(Joey Matschulat from Tyler, TX)
Might be a win-win for both, as Jennings takes his shot at delivering a year that really puts him in the winner's circle in the subsequent winter. Although I always hate to see a pitcher who can hit a little see that ability get wasted in the AL. (Christina Kahrl)
