Cashner to return from DL for Arizona series

LOS ANGELES -- Two lengthy stints on the disabled list have essentially derailed Andrew Cashner's 2014 season, though the Padres pitcher isn't about to let them ruin it.

"I have had some injuries and that's unfortunate, but the biggest thing for me now is taking the ball the rest of the season and showing them I'm healthy," Cashner said Tuesday.

Cashner will get that opportunity this weekend in Arizona when he's reinstated from the disabled list and the team sticks him back in the starting rotation Saturday.

"I'm ready to go … I can't wait," Cashner said.

Cashner made his second and final Minor League rehabilitation start Monday for Triple-A El Paso, as he allowed three runs on four hits in five innings.

Cashner has been on the disabled list since June 21 with right shoulder soreness. He missed three weeks in May with right elbow soreness.

Cashner said he's healthy now and his stuff felt crisp on Monday, leading him to believe that he's ready to jump back into a big league rotation.

"My breaking ball was better, my sinker was very good, I threw some good changeups," he said. "Overall ... my pitch execution was very good."

Cashner is 2-6 this season with a 2.36 ERA in 12 starts. He is eyeballing 20 starts and said he'd like to get "seven or eight" more starts before the end of the regular season.

That could be tough if the Padres follow through with their plan to utilize a six-man rotation during the final month of the regular season, though that hasn't been determined.

Hahn sent down to ease workload; Garces called up

LOS ANGELES -- The last time the Padres were at Dodger Stadium, the team optioned pitcher Jesse Hahn to Double-A San Antonio right before the All-Star break as a way to monitor his workload.

On Tuesday, right before the team opened a three-game series against the Dodgers, the Padres did that very same thing, sending the 25-year-old back to San Antonio for a break.

Hahn's reaction was the same Tuesday as it was in July when he first received the news.

"The competitive side of me is a little bummed," he said.

The Padres have talked since the start of Spring Training about being vigilant regarding Hahn's innings. After throwing 69 innings last season, Hahn is at a combined 110 1/3 innings between stints with San Antonio and the Padres.

"My arms feels good, I don't feel tired ... I hope I'll be back here soon," Hahn said.

San Diego manager Bud Black said Hahn will return when the rosters expand -- from 25 to as many as 40 players -- on Sept. 1. What hasn't been determined, Black said, is if Hahn will return a starter or a reliever.

"I know this organization cares about me and cares about my arm," said Hahn, who missed the 2010 season after having Tommy John surgery and has been slowly been building his workload ever since.

Andrew Cashner will return from the disabled list this weekend and jump back into the starting rotation. He'll get a stat during a weekend series in Arizona, Black said.

To take Hahn's roster spot, the Padres promoted 24-year-old left-handed reliever Frank Garces from San Antonio. Garces had a 2.07 ERA in 61 innings with 44 hits allowed and 73 strikeouts.
