Mitchell sits squarely on the roster bubble heading into the offseason, and Monday is believed to be his final start. He’s been better since returning from a right-elbow impingement, posting a 3.38 ERA in three starts.
The southpaw got considerable run support in his last start Tuesday, when the Giants defeated the Padres, 5-4. Holland gave up four runs, the most any club had scored on him since Aug. 10, when the Pirates put up five.
