Oakland shortstop Bobby Crosby went on the 15-day disabled list Saturday with a strained left hamstring, giving the A's seven players on the DL, according to an Asscoiated Press report.

Crosby had started the A's first 84 games this season before he was sidelined Thursday. His DL stint is retroactive to July 3, meaning he won?t be back until after the All-Star break.
