The deal has not yet been officially announced, as it is contingent upon Choate passing a physical examination.
Between the two stops, Choate had a 3.03 ERA in 80 games, tied for the most appearances in the majors. He held left-handed batters to a .158 average (16-for-101) but righties were a different story as they hit a collective .325 against him (13-for-40).
Choate was originally drafted by the New York Yankees in 1997. He spent his first decade in the majors with the Yanks, Diamondbacks and Rays before signing with the Marlins as a free agent prior to the 2011 season. He also spent time in the minors every year of his career through 2009, including the entire 2008 season with Milwaukee's Triple-A club.
The Texas native's career ERA is 4.02 with lefties having managed only a .201 average against him. Righties are at .279. In very limited action, left-handed hitting Reds stars Joey Votto and Jay Bruce are a collective 0-for-5 vs. Choate. They will likely be seeing each other much more often over the next three seasons.
Once this move is official, the Cardinals' 40-man roster will be full at 40. The club will need to clear a spot if they want to add a player via this week's Rule 5 Draft. To see the entire Cardinals system, by level and position, check out the Roster Matrix at The Cardinal Nation blog.
Update Friday, 12/7: The deal has been finalized. Reports have Choate's annual salary broken down as $1.5 million/$3 million/$3 million.
