A's put Ellis on DL with ailing hamstring

OAKLAND, Calif. -- Athletics second baseman Mark Ellis returned to the lineup Tuesday night only to realize his injured left hamstring still hasn't fully healed.

Oakland placed Ellis on the 15-day disabled list Wednesday, a day after he left early in the A's 7-3 loss to the New York Yankees when his hamstring began bothering him again on his first at-bat. He had just come back after missing the previous seven games with the injury. An MRI exam revealed tendinitis in the hamstring area just above the back of the knee.

A's manager Bob Geren is confident Ellis will be ready to return as soon as he's eligible to come off the DL. Ellis was off to an uncharacteristically strong start, batting .323 with three RBIs in eight games.

Catcher Landon Powell was recalled from Triple-A Sacramento to fill Ellis' roster spot.
