UPDATE: Susan Slusser of the San Francisco Chronicle says Griffin’s MRI turned up clean.
4:57 PM: Lee reports that Griffin exited due to right shoulder tightness.
4:46 PM: According to Jane Lee of MLB.com, Athletics right-hander A.J. Griffin left his start against the Blue Jays this afternoon in the top of the second inning with an apparent injury.
No word yet on the exact nature of the injury, but Griffin’s velocity took a pretty big dip over his final couple of pitches. He was visited on the mound by Athletics manager Bob Melvin and team trainer Nick Paparesta before being replaced by Jordan Norberto. Not what you want after last night’s 15-inning marathon.
Griffin has been a nice surprise for the A’s since making his major league debut on June 24, posting a 2.42 ERA and 35/10 K/BB ratio in 44 2/3 innings. Susan Slusser of the San Francisco Chronicle notes that Brandon McCarthy is slated to make his latest minor league rehab start with Triple-A Sacramento tonight, so he would be on his regular turn if needed. McCarthy has been sidelined since June 19 with a right shoulder strain.
