Given that he changed his approach from strong slap hitter that occasionally pops a HR I'm not seeing the .300+ hitter outside of peak years, but I could be proven wrong, my guess is still things are going to balance out, but his balancing out won't be Inciarte like in that he goes LONG stretches without a long ball, it'll be his rebound from the left side against RHP continues, he hits more singles, starts walking more, and ends up at about .280/.330/.450, with his right side being absolutely killer and left side being average to slightly above, passable enough to not bring things down for him.
Or I could see around .300/.350/.480 as a high side.
Considering in most cases, patience can be learned with time, it's very possible his normal season might be around an .800 OPS.
