Since 2013 includes 2014, 2015, 2016 and 2017.
His decline actually started from 2011 to 2012, but he was still decent in 2012.
While his UZT/150 was plus 3.4 in 2014, and one could consider that a decent year, a .739 OPS at 3B doesn't quite cut it for me.
Obviously from 2015 to now, he's been a complete disaster.
Worst or second worst 3B OPS (550+ PAs).
Worst UZR/150 by a 3Bman (-22.0- a full 7 points worse than number 31, Danny Valencia)
