Adam Wainwright’s comeback from Tommy John elbow surgery got off to a rough start, as he allowed 15 runs in his first 14 innings after missing all of last season.
Those early struggles have kept Wainwright’s overall numbers looking mediocre, but a closer look reveals that he’s been pretty close to his usual, top-of-the-rotation self for a while now.
Wainwright has a 3.74 ERA and 84/25 K/BB ratio in 89 innings since that rough three-start stretch to begin the season, allowing just five homers in 14 starts. And since tossing a complete-game shutout on May 22 he’s thrown 59 innings with a 3.66 ERA and fantastic 58/13 K/BB ratio.
His batting average on balls in play hasn’t been very good and that in turn has inflated his ERA a bit, but based on Wainwright’s secondary numbers and velocity he’s basically all the way back. His average fastball has clocked in at 90.3 miles per hour over the past 60 days, compared to his pre-surgery career mark of 90.7 mph, and his Expected Fielding Independent Pitching (xFIP) of 3.09 overall this season is nearly identical to his 3.02 mark in 2010 and slightly better than his 3.32 mark in 2009.
It remains to be seen how well Wainwright can hold up physically as his workload approaches 200 innings, but if he doesn’t wear down don’t be surprised if he’s one of the best pitchers in baseball during the second half.
