Hahn eyeballing increase on innings limit

LOS ANGELES -- Jesse Hahn is absolutely certain when he's pitching next for the Padres, though he's not entirely sure when or how often it will occur after the All-Star break.

Not just because the Padres -- like about every other Major League team -- will reset their rotation after baseball's midseason breather, but because the team will take a close look at his projected workload for the second half.

Hahn, who starts Friday against the Dodgers, has pitched 73 innings this season between Double-A and the big leagues. He was initially targeted to throw about 110 innings this season after throwing 69 innings last year in the Rays' Minor League system.

But that initial projection, made in Spring Training, is likely due for an adjustment -- and an increase -- as the Padres look ahead to the second half.

"Having him reach new thresholds is important for his growth as a pitcher," said Padres assistant general manager A.J. Hinch. "He's done a great job with the added workload."

Hinch said that he will discuss with manager Bud Black, pitching coach Darren Balsley, bullpen coach Willie Blair and others in the front office to determine where the rookie should end up.

It's a conversation Hahn himself wouldn't mind being privy to, though for now the 24-year-old will keep taking the ball every fifth day until he can't.

"Right now, I have to do the best I can not to think about it. It's not my decision. At the end of the day, someone else is making that decision for me," Hahn said. "If it was up to me, I'd pitch the whole year. I just need to make sure I'm healthy and go out and pitch every fifth day until they tell me I can't.

"But I know I'm not going to throw 150, 170 innings this year."

Hahn has impressed in a small sample size, going 4-2 with a 2.34 ERA in six starts and 34 2/3 innings. He allowed three runs over seven innings the last time out against the Giants. He was stressed early in that start and went to his changeup more often than he has during any other time this season.

"The last game was the first time I really had to make an adjustment," Hahn said.

Hahn's fastball and big curveball -- a plus-pitch for him -- have allowed him to hold opposing hitters to a .192 average. He hasn't faced the Dodgers yet. He knows there's a new test every five days. So far, he's enjoying the challenge.

"This is the best my arm has felt in a long time," said Hahn, who had Tommy John surgery in 2010 and had his innings monitored very closely with the Rays thereafter.

"Just to be on the field every fifth day again is great. I always knew I could pitch. Being up here has been such a great learning experience."

Gyorko begins workouts at club's Arizona facility

LOS ANGELES -- For a few hours Thursday afternoon, Jedd Gyorko took batting practice, fielded ground balls and ran without restriction under the scorching Arizona sun.

He felt like, Gyorko said, a normal baseball player again.

"I kind of forgot what that was like," Gyorko said by phone.

On the disabled list since June 4 with plantar fasciitis in his left foot, Gyorko had his most comprehensive workout on Thursday at the team's Spring Training facility in Arizona, a session that included running for the first time.

"I put on the cleats and ran and had no pain at all," Gyorko said. "Today was an important day. I took BP and grounders and moved around and felt good."

Gyorko will remain in Arizona until Sunday, when he'll fly back to San Diego and then head to the team's Class A affiliate in Lake Elsinore to continue his workouts. He will return to San Diego sometime mid-week to be examined by the team doctors.

But for now, so far, so good.

"Today was an important step," he said. "We'll keep ramping it up from here."

Gyorko was hitting .162 in 204 at-bats with five home runs and 24 RBIs before heading to the 15-day DL on June 6, retroactive to June 4.

Gyorko had a big rookie season for the Padres, hitting 23 home runs, 26 doubles and 63 RBIs in 125 games last year.
