Hahn's nasty stuff on display in A's debut

OAKLAND -- Jesse Hahn didn't disappoint in his A's debut on Tuesday. The right-hander surrendered few hard-hit balls in six innings against a lefty-heavy Rangers lineup -- despite exiting the night with a 3-1 loss at the Coliseum.

All three runs were attached to Hahn, who offered up a pair of RBI singles to Prince Fielder -- the second of which sailed past Craig Gentry in right field in the fifth, leading to the third run.

"If I don't make that third error, maybe they don't score that third run, and it's a 2-1 ballgame," said Gentry. "It's unfortunate, but it's part of the game. I thought Jesse did a great job. We just couldn't get anything done for him."

Hahn struck out three and didn't walk a batter on a 91-pitch night, but he did hit two with his sweeping curveball -- including Rougned Odor, who came around to score on Fielder's first hit in the third.

"I tried to do too much with my curveball and got a couple guys on the foot there, which led to baserunners," Hahn said, "and unfortunately one of them scored."

Fielder's RBI single, error

The 25-year-old Hahn, acquired from the Padres in the Derek Norris deal in the offseason, relied on his signature curve for two of his three strikeouts though, and he also turned to the changeup often -- a pitch he spent much of his spring fine-tuning.

"I think it played big-time tonight," said Hahn, who will be opposed by Felix Hernandez and the Mariners in his next start on Sunday. "I thought it was a really, really good pitch tonight, especially the first couple pitches to Fielder there. I threw him off a little bit. Anything to keep hitters off my fastball and my curveball, just to show it. And I think I did that tonight.

"Overall, I felt good about it, just wish we got the win."

"I thought he threw the ball well," said manager Bob Melvin. "Really the only hard-hit ball he gave up, in a sequence where he gave up some runs, was to Fielder. He didn't walk anyone, was throwing strikes, we just didn't score him enough runs."
