The powerful bat of Rhys Hoskins backed Mark Appel's career-best effort on the mound on Monday as Triple-A Lehigh Valley shut out Pawtucket, 5-0.

Appel (No. 19), meanwhile, kept Pawtucket off the board for a career-high 8 1/3 innings, as he scattered five hits, issued three walks and struck out a season-high eight batters. He also generated 13 ground-ball outs, all while throwing 79 of his 119 pitches for strikes.

The last time Appel completed eight innings was Aug. 12, 2015, as a member of Triple-A Fresno in the Astros' system. It was also the last time the 25-year-old righty struck out at least eight in a start.
After a shaky start to his season, Appel has allowed one or fewer earned runs in four of his last five starts for the IronPigs, during which he's posted a 1.74 ERA over 31 innings.
