Bido is making progress in his recovery from a blister on his pitching hand that he developed during a May 8 start against the Rangers, and the Athletics still view him as an option for the big-league rotation, Martin Gallegos of MLB.com reports.
After turning in a 2.59 ERA and 1.25 WHIP over 31.1 innings at Triple-A Las Vegas, Bido made a spot start in a doubleheader but was pulled midway through the third inning of the second game, and he was returned to Las Vegas two days later. The right-hander hasn't pitched for Las Vegas since, but he could rejoin the big club as soon as Friday, when Oakland will have an opening in its rotation for a series opener in Kansas City. Bido served as the 27th man for the doubleheader last week, so he's eligible to be called back up at any time.
