Yasiel Puig had the worst season of his short major league career in 2015. His inability to stay healthy made it nearly impossible for him to get hot, and he posted career-lows in almost all offensive stats.
Puig posted a OPS+ of 109 and a WRC+ of 111 last year, so he was still slightly above average in both of those stats. His .255/.322/.436 triple slash was a far cry from his 2014 campaign, in which he slashed .296/.382/.480. Many expected him to take a step forward in 2015, but it was pretty clearly a step back from emerging superstar to slightly-above-average regular.
