A's place first baseman Barton on DL as expected

Athletics first baseman Daric Barton has been placed on the 15-day disabled list as expected because of a strained right shoulder that limited him this spring.

The move for Barton is retroactive to March 24. He appeared in only seven games this spring, batting .176 with a double and no RBIs.

Oakland, which already played two regular-season games against Seattle last week in Tokyo, has 26 active players on its 40-man roster and must trim one more by Wednesday ahead of Friday's home opener with the Mariners at the Coliseum.

The fifth starter job is still to be determined between Graham Godfrey and Tyson Ross, who was set to start Tuesday night in the middle game of the A's preseason Bay Bridge Series against the San Francisco Giants.
