You’ll Never Guess What’s Happening in Spring Training
Everyone knows not to make too much of spring-training numbers. This is a time for everyone to be optimistic. Good results are signs of improvement; bad results are to be dismissed because, come on, the games don’t even count. No one takes this time of year too seriously. Not even the players! But especially the fans. Look around. The current league leader in batting average is Mike Freeman. The current league leader in OPS is Billy McKinney. The current co-league leaders in at-bats are Raimel Tapia and Sam Travis. The Marlins, at 7-4, have a better record than the Nationals and the Dodgers. This is all practice. It’s practice, with the pointless quirk of keeping score.
But a funny thing happens when you have enough high-level baseball players playing enough practice games. As noisy as all the individual numbers are, when the sample size gets large, you can start to see real signal. Even in spring training, baseball has a way of finding its level — spring numbers often predict what we’ll see league-wide the subsequent summer. As such, I’ve gone in to investigate, because I’m impatient. This year’s spring training is roughly 40% complete. The league is past 15,000 total plate appearances. What might we be able to tell about the 2018 regular season? The answers might surprise you. (They will not surprise you.)
