Man. What a season so far, huh? The Chicago White Sox are 36-31 after Wednesday’s victory over the Atlanta Braves. They’re in first place in the AL Central. They have a real chance of competing for a playoff spot.
There’s plenty of praise to go around the White Sox locker room. Munetaka Murakami’s power. Miguel Vargas’s All-Star leap. Ditto Davis Martin and his fiendish six-pitch mix. But none of those players is the White Sox MVP through the first third of 2026. The most important man on this roster was bought with the change between Jerry Reinsdorf’s couch cushions: center fielder and bunting gremlin extraordinaire, Tristan Peters.
After a prolonged and painful will they/won’t they, Chris Getz executed what he believed would be a simple one-for-one trade. He traded his old center fielder, Luis Robert Jr., and acquired Luisangel Acuña as his replacement. Acuña had never played the position before, but the goal was to bring him up to speed quickly. Getz projected a center fielder’s glove onto Acuña’s range and athleticism. I’ll even admit that I can see his vision whenever Acuña fields his natural shortstop position. Center field is a different beast, however, and the early-season returns were disastrous for Acuña.
I only blame him so much. Acuña’s been on base just 29 times, and yet he’s managed to rack up 11 steals, so you can’t call him lazy. I’m sure he worked hard at it, but he was put in an impossible position. Oneil Cruz struggled with the same transition, and he’s an athletic marvel. Acuña’s failure falls on Getz.
Had it not been for Peters, there’s no telling where the Sox would be in the standings. The Mune/Vargas/Martin Renaissance could have all gone for naught. It’s not a stretch to say that Peters saved the Sox from their opening swoon:
Now, I won’t sugarcoat it; I simply do not believe Peters is an .800 OPS monster. His Savant batting profile ranges from dark blue (bad) to gender reveal blue (respectably bad), except for a 67th percentile strikeout percentage. The one thing he’s shown is a supersized ability to pull the ball when he does launch it, as his pull percentage on fly balls is 8.4% above league average. Beyond that, the real Peters most likely resembles the man we saw in the first six weeks of this season: a respectable .280 average with a few walks, a smattering of extra base hits, plenty of sacrifice bunts, and an OPS+ hovering around the mid-80s.
I’m not mad about that. Peters’ real value comes in two areas that never slump: baserunning and fielding. The Statcast percentiles make that clear enough. As of the end of play on June 9 — henceforth to be known both as Braden Montgomery Day and as the first time Bob Costas got sick of seeing a team bunt — Peters is in the 89th percentile of baserunning value and the 96th percentile of fielding run value.
Peters’ baserunning pops off the screen. He makes smart decisions and commits to them full throttle, a perpetual motion machine fine-tuned for the 180 feet between first base and third. I shouted out a play on Sunday against the Phillies that won’t show up in his stats but exemplifies his baserunning skill. With Peters on first and two out, Drew Romo slashed a sharp grounder up the middle that second baseman Bryson Stott knocked down. He recovered in time to throw out Romo by a step. It was a great play by the Phils’ keystone man.
As Stott was still scrambling at the edge of the grass, Peters briefly appeared at the bottom of the TV screen. Peters hadn’t slowed down. In fact, he made the turn around second as though the ball had reached the right field wall. Had Romo managed to beat the throw, Peters would have gone first-to-third on an infield single.
And yet! If we’re ranking Peters’ skills, baserunning would still be in the A-tier alongside sacrifice bunts, drag bunts, and being your dad’s favorite player to the point where it’s a little uncomfortable. Above them all, in the S-tier, is the Gold Glove-level fielding he brings to baseball’s most important outfield position.
Peters has seven outs above average (OAA), according to Savant, ranking him fourth in all of baseball. I went ahead and checked some of the underlying metrics, something I had never done before. Definitions for reaction, burst, and route were oddly difficult to find on Baseball Savant’s website. Still, thanks to a Samford University abstract posted online in 2020 by a high school senior named Jake, I finally tracked down this handy infographic:
Baseball Savant/Jake
With that out of the way, I’ll now show you the top 10 leaderboard for OAA. Fair warning, these numbers are going to seem very complimentary of Peter Crow-Armstrong. I’ll try my best to twist them into a negative:
These numbers show that a good center fielder can go about their business in one of two ways. In both cases, burst is non-negotiable. The difference is in how you use that burst. Some guys use it, along with quick reaction time, to compensate for less-than-stellar routes. Like Crow-Armstrong. Looks like you’re just a fast dummy, Pete!
The second are the guys who may not react quickly, but they read the ball well off the bat and optimize their route to the baseball. That’s the smarter kind of outfielder. It’s the rarer kind. It’s more likely to age well:
Among the top ten, Peters and Steven Kwan are the best route runners. Unlike Kwan, Peters also has an acceptable (not exceptional) reaction time. I can’t help but feel like Robert Jr. for Peters would have been a pretty fair deal.
Hustle? Defense? The ability to make up for Getz’s worst decisions? That’s your 2026 White Sox MVP.
