Ross, who was designated for assignment Saturday, was released by the Athletics on Tuesday, MLB.com's Jane Lee reports. The 34-year-old Ross posted a .628 OPS over 202 at-bats for the Diamondbacks last year, and he was off to a 2-for-22 start with the A's this season. He may be able to find work elsewhere as a right-handed bat off the bench, but it's also quite possible he'll have to settle for a minor-league gig. While his track record against left-handed pitching is strong, he only managed a .639 OPS versus southpaws last season.
