St. Louis was initially targeting Sean Burnett as a left-handed bullpen addition, but after finding his price tag too high the Cardinals have moved on to Randy Choate.
Choate, unlike Burnett, is strictly a left-handed specialist rather than a left-handed setup man. In fact, in leading the league with 80 appearances this year he threw a grand total of just 36 innings.
He’s basically only good for a batter or two every other game and right-handed hitters tee off on him, but during the past three seasons Choate has limited left-handed hitters to a .173 batting average.
UPDATE: Choate is getting $7.5 million for three years, which is … well, more money and a longer commitment than anyone could have expected.
