The Athletics announced Thursday infielder Adam Rosales has been activated from the 15-day disabled list. He was on the DL with a strained intercostal muscle that has kept him out of major-league action this season.
Rosales hit .320/.370/.520 with one home run in 25 at-bats during a six-game rehab assignment. Andy Parrino was optioned to Triple-A in a corresponding move.
