Petricka, 29, saved 14 games and posted a 2.96 ERA over 67 games in 2014. He followed up that effort with a 3.63 ERA over 62 games in '15. But Petricka appeared in only nine games as part of the '16 campaign before undergoing season-ending surgery on June 10 to repair a labral tear in his right hip.
Although he appeared in 27 games during the '17 season, Petricka was once again bothered by injuries and finished with a 7.01 ERA and 39 hits yielded in 25 2/3 innings. Petricka recorded 26 strikeouts against six walks, but finished the season on the disabled list with a right elbow strain.
