Hunter allowed two hits while tossing the club's first complete-game shutout in three years as Bowie defeated Erie, 6-0.
Hunter retired 14 in a row to start the game before walking Daniel Fields with two outs in the fifth inning. The 26-year-old right-hander gave up his first hit an inning later -- a one-out single to Luis Alberto Sanz. Hunter faced three over the minimum and threw 72 of his 99 pitches for strikes.
"I kept the ball down for the most part, and you win ballgames when you keep the ball down," he said. "What happened tonight would work anywhere. I was able to throw strikes early in the count and down in the count and that's what helps.
"Every time you go out, you want to be perfect," Hunter said. "That's first and foremost. I was upset about the walk -- that wasn't very good, but the fastball in the last inning was a well-hit ball and that's one where you tip your cap because he got me."
Hunter, who fanned four, was sent down to Bowie on Aug. 24 after going 4-8 with a 5.95 ERA in 23 outings for the Orioles. The five-year Major League veteran should provide a boost for a team in the midst of a playoff race, a fact not lost on Baysox manager Gary Kendall.
"That's how it's done I guess," Kendall said. "First of all, to see a starter out there in the ninth inning was impressive. He had a good downward angle, was getting ahead and throwing all his pitches and mixing well. Just the confidence he exuded from him to our players. He was at his 'A' game here. With the angle he had with his fastball and breaking ball, I think he could have gotten guys out anywhere."
Hunter is the first Bowie hurler since Brian Matusz on July 2, 2009 to go the distance with a shutout. It's also the first complete-game shutout at any level for the Indiana native.
Ronnie Welty homered twice and drove in three runs while Robbie Widlansky was 2-for-4 with two RBIs for the Baysox.
