Lifetime OPS for Wilkerson:
Looks like he hits in June usually. And ALL players have ups and downs like he does.
RFK is an extreme pitcher's park, so Wilkerson's "slump" has a big park effect associated with it. Notice he had just 6 fewer hits last year, and had 60 total extra base hits (compared to 73, 57, and 55 the prior three years). The problem is that RFK turned 10-20 homers into doubles and triples.
