What the hell happened to Carlos Gonzales?

2016 : 632 PA, .298/.350/.505 with a 108 WRC+ and worth 1.9 fWAR

2017: 311 PA, .218/.296/.335 with a 47 WRC and worth -1.7 fWAR (worst among qualified position players)

He doesn't turn 32 until October so its not like he was a 40 year old who caught lightning in a bottle last year
