Brett Anderson (oblique) will miss the rest of the regular season. Anderson left Wednesday's start against the Tigers after just 2 1/3 innings with tightness in his right oblique. He hopes to be back for postseason play, but Oakland will monitor how his rehab goes. In six 2012 starts, Anderson went 4-2 with a 2.57 ERA over 35 innings. Travis Blackley will take his spot in the rotation.
