Troy Patton holds a 4.05 ERA over 18 appearances.

The left-hander put up a 2.43 ERA over 54 appearances last season in his first full year in the majors. His encore isn't going as smoothly due to an increased rate of walks (more than double what it was last season) and decreased strikeouts (he's punching out 3.4 less batters per nine innings). Being increasingly hittable doesn't help either. After a 1.02 WHIP in 2012, Patton sits at 1.55 today.
