The Athletics have announced that they’ve designated lefty Brad Mills for assignment. They also optioned righty Aaron Brooks to Triple-A Nashville and recalled righty Dan Otero and switch-pitcher Pat Venditte.
The A’s added Mills to their roster yesterday so that he could make a spot start against the Orioles. He pitched five innings and allowed three runs, all of them coming on a homer to Adam Jones, as the Athletics lost 8-6. In parts of seven big-league seasons, Mills has a 7.
