The lefty Cervenka has pitched primarily in relief over the past two seasons. In 2012, he sports an unimpressive 8.62 ERA, but he is striking out 1 out of every 3 batters, while walking only 16% -- good for a solid 3.46 FIP.
The acquisition of Cervenka completes the April 21 trade that sent CF Marlon Byrd to Boston in exchange for RP Michael Bowden and a player to be named later.
