OAKLAND -- Left-handed starting pitcher Drew Pomeranz landed on the disabled list Tuesday after fracturing his right hand by punching a wooden chair after the worst start of the season Monday.

Pomeranz, charged with eight runs (seven earned) in 32/3 innings of a start with the Rangers, said he hit the chair walking up the corridor from the field to the A's clubhouse after leaving the game.

"It was pure frustration,'' Pomeranz said. ``You never want to come out of a game after putting your team in an 8-2 hole. That's real frustration.''

It could have been worse. Since it was his right hand, as soon as Pomeranz can comfortably play catch he can start on the road to returning to the A's rotation. He said he will continue throwing on the side as if he were starting.

His rash action could wind up hurting the A's as much as it hurt Pomeranz. Oakland, which called up reliever Evan Scribner from Triple-A Sacramento, will have to find a starter for what would have been Pomeranz's next scheduled start Saturday against the Red Sox.

One candidate on the big league roster is left-hander Jeff Francis, picked up from the Reds on waivers on May 18, has been pitching out of the bullpen, but his 0-1 record and 8.22 ERA may have the club look in other directions.

Dan Straily, who was sent down to the River Cats when Pomeranz moved into the rotation, has been pitching well for Sacramento with a 4-1 record and 3.55 ERA in seven starts and could find this his ticket back to the big leagues.

  • The A's added a left-handed starter, Brad Mills, to the organization Tuesday, getting him from the Brewers for what was called cash considerations.

    Mills, moved up on to the Triple-A Sacramento roster, was 4-2 with a 1.56 ERA in 75 innings at Triple-A Nashville this season after having spent part of the 2013 season playing in Japan. He's started 12 times and relieved twice.

    In part of four seasons in the big leagues with the Blue Jays and the Angels he's 3-3 with a 7.76 ERA.
