Daric Barton was in the starting lineup at first base Saturday while Kila Ka'aihue moved to DH.
"He's a guy we expect to pick it up and do well for us," manager Bob Melvin said of Barton. "We had planned to play him today [with right hander Jeremy Hellickson starting for the Rays] regardless."
Brandon Inge, who is hitting .133 since joining the A's and .114 for the year, was dropped from sixth to ninth in the batting order Saturday.
"He's a guy who doesn't care where he hits, and he's capable of hitting in just about any spot in the order. It is more about the other guys that about him."
Josh Donaldson, who was sent to Triple-A last month because of his struggles at the plate as the A's starting third baseman, was batting .500 with three homers and 10 RBIs in his first six games at Sacramento.
