Perez recorded a 4.17 ERA with 51 strikeouts last season in 70 relief appearances with the Diamondbacks and Astros, who acquired him in a a midseason trade. He held lefthanded batters to a .185 average. The Nationals’ bullpen is currently without an experienced lefthanded reliever, and Perez should slot in somewhere in the late innings.
Perez struggled with his control as a starting pitcher early in his career, but since moving to the bullpen full-time in 2012 holds a 3.31 ERA.
