Bobby Witt’s fielding did a 180
One of the most alarming outcomes from 2022 was Bobby Witt Jr.’s fielding ability, or should we say, lack of fielding ability. Witt was the worst defensive shortstop in Major League Baseball last year, and he was better at third base but only somewhat.
To be sure, Witt’s problems at the plate are a bigger deal, as Witt has doubled and tripled down on his “be Salvador Perez but without Salvy’s bat control and hit tool” approach, which. Not good! But his defense was still important. Put it this way: Witt has regressed at the plate but is pacing to be more valuable than last year. That’s because he has been just a way better defender.
If you’ve been here for a while, you know I like to average out multiple defensive stats and prorate them per 1000 innings (a full defensive season at one position). Using Defensive Runs Saved, Ultimate Zone Rating, and Runs Above Average—together or individually—the improvement Witt has shown is astounding.
Bobby Witt’s Fielding Improvements at SS
Stat 2022 2023 Improvement
DRS -18 -1 17
UZR -6.5 -0.3 6.2
RAA -7 4 11
AVGDef -10.5 0.9 11.4
AVGDef/1000 -12.7 2.7 15.4
That last stat is the big one—Witt has improved by 15.4 defensive runs per 1000 innings so far this year. That is...a lot. For context, that is roughly on average what UZR and DRS said Lorenzo Cain was worth defensively in the 2013-2015 years. This is why Witt is pacing for a 3.5 WAR season even though his offense has regressed: the difference between “good shortstop” and “awful, unplayably bad shortstop” is immense. And if he’s this good defensively moving forward, that puts the offensive bar for him to be an All-Star much lower (while also raising his ceiling that much more).
