Zerpa (0-1) was tagged with the loss Thursday after allowing two runs (both unearned) on three hits and a walk while fanning four across five innings.
The young left-hander made his big-league debut in the series finale and while he was tagged with the loss, he looked composed while tossing 44 of his 68 pitches for strikes. Zerpa posted a 2.59 ERA across eight starts at High-A Quad Cities and will probably start next season at Double-A, but this outing was certainly encouraging for his long-term outlook.
