A bit, but nothing substantial
Hard Hit Rate:
40.9% in April, 40.6% in May
Barrel Rate:
9.6% in April, 10.3% in May
GB Rate:
37.8% in April, 42.3% in May
K's and BB's both went the wrong way as well, but less than a percentage point for each.
Add it all up and the team's xwOBA has dropped a bit, from .350 in April (4th in MLB) to .341 (9th) in May.
Their actual wOBA on the other hand has dropped from .348 (3rd) to .311 (16th).
It's luck, these things ebb and flow. Everyone wants to make it some big failing but it's just something that happens.
