Placed LHP CC Sabathia on the 15-day Disabled List (oblique)
This is the first trip to the DL in Sabathia's four-year career, and it doesn't look like he'll miss much time. Jason Davis, who looked good against the Reds on Friday, will take Sabathia's place in the rotation, and Matt Miller and Rafael Betancourt should both make the club as result. Jake Westbrook is slated to be the Opening Day starter.
Optioned Kazuhito Tadano to Buffalo (AAA)
Kaz didn't have too good a spring, posting an ERA of 9.00 (10 innings pitched). I'm going to assume he's still a starter, but that might be subject to change depending on the needs of the big-league club. The Bisons' pitching preview says Tadano could be either a starter or a reliever.
Assigned OF Andy Abad, IF Mike Kinkade, 1B Jeff Liefer, OF John Rodriguez, RHP Denny Stark, C Dusty Wathan, and LHP Chad Zerbe to minor-league camp
Most, if not all, of these players are going to play in Buffalo this year. Stark looks to be in the rotation, Liefer should be the starting first baseman, and Wathan will be Ryan Garko's caddy.
I've updated the Options page; after the season starts, I'll add salary and YOS info to the page as well.
