Yeah at some point the scorching hot start will be overshadowed by his ice-cold period. From March-April 15th he had a wRC+ of 258 and 1.297 OPS and a BABIP of .500
From April 16 to May 13 He's had a wRC+ of 74 and .580 OPS with a BABIP of .233 so a bit unlucky, but not nearly as big a swing as he was with the luck in March through April 15th.
At some point, you have to be concerned that he doesn't make the adjustment back. I'm sure we'll know more in another months time and hopefully, he settles somewhere in the middle. I said much earlier during his scorching hot streak that I would be happy with a .780 OPS out of him, I think I'd take the under going forward for the rest of the year.
