A.J. Pollock’s Second Breakout
In 2015, A.J. Pollock posted the sixth-best WAR in baseball. The Arizona Diamondbacks center fielder put up 6.8 WAR — a total that trailed only Bryce Harper, Mike Trout, Josh Donaldson, Joey Votto, and Paul Goldschmidt. The 27-year-old hit 20 homers, stole 39 bases in 46 tries, rarely struck out, and complemented all that with good defense for a great season.
A fractured right elbow right at the start of the 2016 season robbed Pollock of a chance at a repeat, and last year he turned in a diminished version of his 2015 season while missing time due to a groin strain. Last year might have put to rest any ideas that the Pollock of old would return. The 2015 Pollock hasn’t returned this season, either. Rather, we’ve seen a new-and-improved Pollock who could be better than the burgeoning star we thought we had three years ago.
Through 33 games, Pollock already has 10 home runs, three triples, and nine doubles, his 22 extra-base hits tied with Mike Trout and behind only Mookie Betts and Ozzie Albies. Pollock’s .306/.362/.669 line produces a 173 wRC+ that ranks fifth in the sport, with his 2.1 WAR coming in behind only Trout, Betts, and Didi Gregorius. He’s on his way to a great year, and through the first 33 games of the season, he’s hit better than he ever has. The graph below shows Pollock’s 33-game rolling average of his wRC+ over his career.
