The A's designated pitcher Dana Eveland for assignment, according to MLB.com's Jesse Sanchez. Oakland called on the 25-year-old lefty to replace Dallas Braden Monday night, but Eveland struggled, allowing four runs and nine baserunners in less than three innings, so he'll return to Triple A.
He faltered in six games for the A's this year, but has fared better in Triple A. His 7-1 record and 3.49 ERA are slightly misleading, but he hasn't allowed many hits or homers in his 12 minor league starts.
As Assistant GM David Forst explains in this MLB.com article, the A's are essentially optioning Eveland to Triple A and aren't at risk of losing him to another club through waivers. He has to clear optional waivers, something no player has failed to do since they were implemented.
