Hess throws his first complete game for Keys

It took him 31 pro starts, but Orioles No. 10 prospect David Hess worked through his first career complete game on Tuesday afternoon.

The 22-year-old right-hander out of Tennesssee Tech delivered seven innings of one-hit ball for Class A Advanced Frederick in the first game of the Keys' doubleheader. Hess' near perfect performance included one walk and five strikeouts as Frederick took down Potomac, 4-0.

Selected in the fifth round of last summer's Draft, Hess has spent all season in Advanced ball and stands at 9-4 with a 3.58 ERA in 25 starts. He has not lost in his past 12 outings, a run that began on June 27.

In fact, Hess has not allowed more than two earned runs in any start since giving up six to Carolina on June 15.
