He's in the top 20 in strikeout rate. He's in the top 15 in FanGraphs' wins above replacement. He's in the top 10 in the American League in wins.
And we want to know why he's struggling. Because he's Justin Verlander.
Verlander hasn't had an ERA (3.59) this high since 2008, is walking a full batter per nine innings more than last year, and has given up more than five runs in a start six times this year. He did that half as many times last season.
It's fair to conclude that something just isn't quite right with the 2011 AL MVP and Cy Young winner in 2013. At least that's what it looks like. The good news for Detroit is Verlander has started to look like his former self of late.
