Mahle (forearm) allowed three runs on six hits and no walks over four innings in a start versus minor leaguers Thursday, Kennedi Landry of MLB.com reports.
Mahle threw 55 pitches in the outing and an additional 10 pitches in the bullpen afterward. The right-hander was scratched from a scheduled Cactus League start earlier this week due to right forearm soreness, but an MRI came back negative, and it appears Mahle is back on track.
