EDGE Analysis

Wainwright has been limited to just four starts this season due to an elbow injury, but he's been cleared to rejoin the big-league rotation after firing five scoreless innings in his sixth and final rehab start over the weekend. The veteran right-hander appears ready to go, as he struck out 23 while not allowing a run across 17 innings during his six-game rehab stint. He owns a 4.00 ERA across 18 innings with the Cardinals this season.
