EDGE Analysis

O'Day has been dealing with a left calf strain since mid-July, but he had been with the Triple-A club on a rehab assignment since Aug. 9. He's posted a 2.57 ERA and 1.00 WHIP in seven innings over seven rehab appearances at the Triple-A level, but it's not yet clear how his toe injury will impact his return timetable.
