Oswalt asks to be dealt

Astros ace Roy Oswalt wants out of Houston.

General manager Ed Wade said Oswalt’s agent, Bob Garber, contacted owner Drayton McLane earlier this week to make the request.

Oswalt, 32, recently said he would be willing to waive his no-trade clause.

Wade said he wants to win with Oswalt on the Astros. Houston is 15-27 after defeating Tampa Bay 2-1 on Friday.

Oswalt has made nine straight quality starts to open the season but is 2-6 with a 2.66 ERA. He has received the lowest run support in the league.

Crisp makes A’s debut

The A’s activated their new center fielder and leadoff man for the team’s interleague opener against the San Francisco Giants in the Bay Bridge Series. He had been suffering from a broken left pinkie.

Maine headed to DL

Mets pitcher John Maine is heading to the disabled list with right shoulder weakness, a day after getting pulled from his start after only five pitches and getting into a dugout spat with manager Jerry Manuel.

The move was announced only a couple hours after Maine stood in front of his locker in the Mets clubhouse and insisted that he felt fine.

Maine spent three months on the disabled list last year with a tired right shoulder.

Maine didn’t have much velocity on his pitches when warming up Thursday night,and it didn’t improve much against leadoff hitter Nyjer Morgan, who drew a walk. Raul Valdes quickly replaced Maine, and the Mets went on to win 10-7.

Television cameras caught Maine in a heated argument with Manuel in the dugout after he was removed.
