Yes, and I agree that the increase in May strikeouts is the main factor in his lower output. He is clearly not producing as well as he was in April, even with normalized luck, as you outlined. However, the reversal of luck is still playing a role in his splits. I believe in his development and his contact profile, so I think that after the next few seasons, including this one, he'll be closer to the April (.945) version than the May (~.700) version.
Taking that literally, I guess I'm basically saying that I still expect an OPS greater than or equal to .8225 this season, which would be a tremendous improvement over last season.
