I find this fascinating: Center fielders outhit left fielders in 2016. While left fielders hit a few more home runs -- 595 to 546 -- center fielders hit .263 compared to .254, drew more walks and hit more triples. They also grounded into far fewer double plays, stole 290 more bases and, of course, played the more premium defensive position.
In other words, center fielders were much more valuable than left fielders in 2016. Center fielders also had a slight edge at the plate in 2015 and 2011, but historically left fielders have always hit better than center fielders.
