SEATTLE -- The Athletics have reinstated left-hander Drew Pomeranz from the 15-day disabled list and optioned him to Triple-A Sacramento, the club announced Sunday.
Pomeranz, who fractured his right, non-throwing hand in mid-June when he slammed it on a chair, was stellar Saturday night with Sacramento in his first rehab start, allowing just one hit on a solo home run over four innings while striking out seven and not issuing a walk.
He'll make his next start for the River Cats on Thursday.
"We'll just see how it all plays out," A's manager Bob Melvin said. "As it is right now, this is the current construction."
Before the injury, Pomeranz went 5-4 with a 2.91 ERA in 17 games (eight starts) with Oakland. The recent addition of starters Jeff Samardzija and Jason Hammel make his return to the big leagues less certain.
"It's terrific depth," Melvin said.
On Sunday, Melvin announced Oakland's post-All-Star break rotation. After four days off, the A's begin a three-game set with the Orioles on Friday. Samardzija will start, then Hammel on Saturday, before Sonny Gray, Scott Kazmir and Jesse Chavez round out the five.
Melvin didn't discount the possibility of Pomeranz rejoining the team as a reliever.
"Drew has shown that he can do it in the rotation and the bullpen, so he opens up some options for himself," Melvin said. "Obviously, he opens up some options for us in both roles."
