Jesús Luzardo Has Risen

Three days ago, Jesús Luzardo was a fun bounceback candidate. As a minor leaguer, he was one of the best prospects in the game, with an explosive fastball, a spectacular array of secondaries, and plus command. In his first two seasons of big league experience, that continued; he missed bats, walked only 6.8% of his opponents, and posted an ERA in the upper threes. But in 2021, his command collapsed, and with it his untouchable status in Oakland. In the midst of a 6.61 ERA season with an 11% walk rate, the A’s shipped him off to Miami in exchange for Starling Marte.
It’s not three days ago anymore. Now, after a dominant start, I’m considering a different question: is Luzardo Miami’s best pitcher? Is he one of the best pitchers in baseball, full stop? That’s probably hyperbole, but again: Luzardo was one of the best pitching prospects in baseball only a handful of years ago. Let’s give his remarkable turnaround the consideration it deserves, and see if we can figure out what changes he’s made to unlock this new level of performance while we’re at it.
First things first: has Luzardo made any changes to his delivery? To figure this out with my remedial understanding of pitching mechanics, I watched one fastball from his 2021 season and one fastball from his 2022 debut over and over (and over and over and over) again. Here are the clips in question. First, a called strike last April:
Next, a foul tip from Tuesday:
I’m hardly an expert here, but I noticed several differences. First, he’s more to the third-base side of the rubber. Second, at the peak of his lead leg’s lift, his glove position is meaningfully higher. Take a look at the two side-by-side and it’s somewhat obvious, even if the different aspect angles from the two broadcasts keep you from making a straight comparison:
