Mahle (0-1) allowed three runs on four hits and four walks over five innings during Sunday's game against the Pirates. He struck out five and was stuck with the loss.
Mahle struggled to find his command during his big-league debut against the Pirates. The 22-year-old sported an excellent 5.3 percent walk rate between Double-A Pensacola and Triple-A Louisville this season, but he wasn't able to display that same prowess Sunday as he issued four walks and hit a batter over his five innings of work. He'll get another opportunity to show off his stuff during his next scheduled start against the Pirates on Saturday.
