Outman to miss next start

Gio Gonzalez likely to replace injured lefty vs. Giants

OAKLAND -- A's left-hander Josh Outman remained listed as the club's probable starter for Wednesday in the notes distributed to the media Monday.

Apparently nobody checked with Outman, who had to leave his start in San Diego on Friday with two out in the second inning.

"I don't see any way I can throw [Wednesday]," Outman told MLB.com before the opener of a three-game Interleague series against the visiting Giants at Oakland-Alameda County Coliseum. "I haven't picked up a ball [since Friday]."

On Tuesday, the A's confirmed that Outman would indeed miss his Wednesday start.

Outman, 24, left the Padres game with what the team listed as tightness in his left forearm. Outman, however, said his elbow is the primary source of discomfort -- and the area on which an MRI exam performed Monday morning focused.

"It's more of a nuisance than anything," Outman said when asked to describe the pain. "It's not killing me."

Whether or not Outman will need a stint on the disabled list, the A's will need a starter for the series finale vs. San Francisco.

Righty Edgar Gonzalez, who replaced Outman and gave up four runs on six hits Friday, is the team's long reliever and opened the season in the starting rotation at Triple-A Sacramento. A's manager Bob Geren has said he's reluctant to use Gonzalez as a spot-starter, though, because he likes having a reliever who can provide length.

Thus, all signs point to the return of lefty Gio Gonzalez, who is 4-1 with a 2.51 ERA in 12 starts at Sacramento this season.

His next scheduled start for the River Cats? Wednesday.

Gonzalez, whose 71 strikeouts in 61 innings rank second in the Pacific Coast League, has been recalled to Oakland twice this season, and twice he was sent down the day after pitching in long relief.

In those two games, he gave up seven earned runs on 11 hits and seven walks while striking out 11, but his command in Sacramento had been improving all year; his strikeouts-to-walks ratio is now better than 2-to-1.

On Monday, Geren wasn't willing to concede that Outman will miss his next turn, so he didn't entertain the notion of who might replace him, but he was plenty vague enough when discussing Outman's MRI to suggest that he, too, knew he'd need another starter Wednesday.

"The doctor isn't here yet, so he'll look at the MRI when he gets here," Geren said during batting practice. "I might have more information on that after the game, or at this time [Tuesday]."

Dr. John Frazier, the A's team orthopedist, will do the looking.

"It's just a waiting game right now to see how bad it is and how much time I'll miss," Outman said. "I don't know anything more than I won't be able to start Wednesday."

Outman, who is 4-1 with a 3.48 ERA in his rookie season, gave up one run on two hits and a walk against the Padres.

Acquired last summer in the deal that sent Joe Blanton to the Phillies, Outman was a 10th-round pick out of Central Missouri State in the 2005 First-Year Player Draft. He made his Oakland debut in September last season, and he's never been on the disabled list or had arm problems as a professional.
