OAKLAND -- Daric Barton left in the fifth inning of Sunday's 3-2 win over the Rangers with left shoulder spasms after advancing to first base on an error by Rangers shortstop Elvis Andrus.
Manager Bob Geren elected to go with Landon Powell as the pinch-runner and said Adam Rosales, a much faster option, was unavailable because of an injured ankle. Powell remained in the game at first base, where he started four contests in 2009. It marked the first time that Powell had played first base all year.
Barton, who leads the A's with 108 games played this year, said he was fine after the game.
