Hentges allowed a hit and struck out one in a scoreless inning during Tuesday's 7-2 loss to Toronto.
Hentges was recalled from Triple-A Columbus on July 22, but Tuesday was his first appearance since rejoining the major-league roster. The 25-year-old has worked as both a starter and a reliever this year, and he's been a long-relief option since his call-up. He owns an 8.04 ERA, 2.02 WHIP and 45:25 K:BB across 43.2 innings in 16 appearances (eight starts).
