Yandy Díaz probably went around. Slow the replay down and the bat gets out far enough that the strike call holds up. In real time it looked like he held it, because he yanked it back fast, and that's exactly how these plays fool everyone on first look. Freeze the frame and the argument tips toward swing. The call was defensible.
So quit aiming your rage at the man in the blue shirt.
Brewers up 5-4, top of the ninth in Milwaukee on Saturday, Jonny DeLuca on third, two outs, full count. Díaz against Aaron Ashby. Home plate umpire Jim Wolf ruled no swing, which sends Díaz to first. Milwaukee catcher William Contreras appealed to first base, James Hoye ruled Díaz went around, and that was the ballgame: 5-4, Brewers, a 2-0 series lead heading into Game 3 in Tampa Bay on Monday. Even Díaz didn't turn it into a crusade. "In the moment, yeah, I disagreed. But the umpire said it was a swing and it is what it is." Kevin Cash, standing up for his guy, still said: "I didn't go look at it, but from my vantage point, it did look like that he swung." When the losing manager and the hitter both shrug, it's easy to mistake this for a close, honest call. The league knew better and did nothing anyway.

Check swings aren't reviewable. The appeal only runs one direction: when the plate umpire calls a ball, the defense can ask for a second look, and that second look is final. The Rays had no mechanism to get their own second opinion. The outcome of a World Series game rested on how fast one human eye could track a bat through a blur. The rulebook doesn't even define what a swing is. It gestures at "an attempt to strike at the ball" and leaves the rest to word of mouth about breaking wrists and clearing the plate. Everybody's screaming about whether Díaz broke some plane. MLB never wrote one.
The league already built the fix. There's a Check-Swing Challenge system tested in the minors, with a Triple-A version using Hawk-Eye to measure bat angle automatically instead of leaving it to a human eye-test. FOX's Joe Davis said it live during the replay: "We got ABS for the first time this year, getting the balls and strikes right; we need to get a system that can get [check-swings] right." He's right. The technology works and it's running. It just wasn't ready for the biggest stage the sport has.
That's a choice. Rob Manfred's league office rolled out automated ball-strike challenges this year and let the check swing stay a campfire story. A World Series game ended on a guess when it didn't have to, and the only reason we're still arguing about Díaz's wrists instead of a Hawk-Eye readout is that MLB couldn't be bothered to finish the job it already started.
