Maybe the guy can make a change to his swing, but he was getting consistent playing time when he started getting crushed. He had forced himself into the line-up with April; and from May 6-June 25, Motter started in 75% of team games (36/48 with 6 Def Replacements/PH) and batted .197/.262/.273. He failed to start for 3 games once over the span, at the end of May when he sat for 4 games after batting .151/.224/.151 while starting 15 of the previous 16 games. I like the guy too, but he hits into the shift worse than almost any hitter in the majors, AND the guys around him on the list A) hit fewer ground balls than Motter (35-39% vs. Motter's 41.8%), B) have WAY more power than Motter (the 3 of the 4 closest players have career ISOs over .215, the 4th is Albert Pujols), and C) STILL have routinely bad BABiPs (Randall Grichuk has the best at .293, the rest are .275 and lower).
If Motter doesn't massively change his batted ball profile, he's doomed to bad BABiPs, and a player of his type can't afford that.
