Technically, there wasn’t much at stake. Even though Mason Miller was looking to protect a one-run lead with two outs in the 10th inning of an early September clash, the A’s and Rangers were playing out the string, battling for wins in a lost season. For Wyatt Langford, however, it meant something more.
On the first pitch, Miller fired 101 mph down the middle. Langford was aggressive, fouling it straight back for strike one. He watched 102 mph sail high, then flicked his bat to foul off an up-and-in 101-mph heater to fall into a 1-2 hole. A slider sailed outside before he fouled off pitches at 102 mph and 103 mph to stay alive, and then he laid off two wicked sliders to secure the base on balls. Langford faced down some of the best stuff in baseball, and emerged the victor.
It was just a walk, but it sparked a resurgence. After a dismal five months, Langford exploded in September, posting a 180 wRC+ and leading the American League in WAR. In the series following his successful encounter with Miller, he blasted titanic tanks off Luke Weaver and Clay Holmes, catching up to heaters at the top of the zone and depositing hanging sweepers deep into the left field bleachers.
It led to a question: Was September reflective of Langford’s new level? The answer, in part, was conditional on prior expectations.
And the expectations were certainly high heading into the season. After landing in Texas with the fourth overall pick in the 2023 draft, Langford incinerated the high minors, posting a .360/.480/.677 line across four levels and 200 plate appearances. ZiPS pegged Langford’s 50th percentile outcome above three wins, reasonably confident that Langford would go from the SEC to an above-average regular in the span of a year. As Cactus League play began, the hype train picked up steam; Langford hit .365 with six homers, leaving no doubt as to whether he’d start the year on the big league roster.
It turns out hitting in the majors is hard. No longer was Langford tasked with fending off the pitching staff of Mississippi State or the El Paso Chihuahuas; instead, he had to deal with Chris Sale sliders, Hunter Greene fastballs, and Tarik Skubal changeups.
Fittingly, he looked like a rookie. The plate discipline was there early on; his walk and strikeout rates hovered around league average, suggesting that Langford was not completely overmatched like his rookie counterpart Jackson Chourio, who struck out over 32% of the time in March and April. But Langford’s batted ball quality was lacking. He slugged just .314 in April, lifting heaps of lazy fly balls into outfield gloves.
Whereas Chourio found his footing in the summer months, logging a 144 wRC+ in June and never looking back, Langford’s line remained stubbornly subpar — until the final month of the season. Finally, as the Rangers slogged through their September schedule, Langford went bananas. His .300/.386/.610 line and excellent baserunning led to 1.6 WAR in that month alone, trailing only the infernal Shohei Ohtani.
There are a few potential stories to tell about the Langford rookie campaign. One is that he ran into a few poorly located pitches across a small sample. Another is that Langford made his adjustments, just as Chourio clearly did, accumulating enough experience against major league stuff to leverage his immense tools.
ZiPS, as always, splits the difference. The projection system sees Langford as a 3.8 WAR, 128 OPS+ guy next year, baking in Langford’s transcendent minor league results with a slight skill bump as he heads into his age-23 season.
But splitting the difference is no fun. This approach, applied to players across the league, will lead to more accurate projections. There is no good empirical reason to weigh September results more heavily in the next season’s forecast. But there is a temptation, at least on my end, to believe that Langford is going to be the player we saw in September moving forward.
In this version of the narrative, the expectation for Langford’s sophomore campaign isn’t just an All-Star 4-WAR season, as ZiPS forecasts; it’s something more like 5 WAR as the 50th percentile expectation, mirroring the age-23 projections for recent breakouts Corbin Carroll and Julio Rodríguez.
To make that argument persuasively, it would require evidence that Langford identified and then fixed the flaws that held him back across his first 400 or so plate appearances. And there is at least some reason to believe he did.
There is no one culprit for a hitter’s poor performance. The reasons are layered and complex; it could be an issue with certain pitch types or certain locations, for example. In Langford’s case, it seemed like at least one of the issues was structural, tied to his hitting mechanics. Both he and Rangers offensive coordinator Donnie Ecker believed his swing was too vertical.
Even two weeks into the season, it was clear that Langford needed to adjust. There was one clear potential area of improvement: His distribution of weight on his swing. In a story written by Steve Kornacki (no, not that Steve Kornacki) at MLB.com, Ecker was quoted as saying that Langford’s mechanical tendencies needed a reboot.
“[Langford] came from college and regularly has not faced breaking balls that are breaking 18 to 20 inches,” Ecker told Kornacki. “So, some of the body position he was in in college is now starting to evolve. If you look where the pressure is at, maybe in college it was on his back side. All of the best hitters in the big leagues, their pressure, when they land [on swings], is in the middle of their body. So, he’s slowly evolving from a guy that’s back, to having to get over the center that’s in the middle of our body.”
Esteban Rivera, FanGraphs’ resident hitting mechanics expert, explained to me that loading up weight on the backside makes it easier for hitters to whip their barrel under the ball and therefore generate power. This approach works well in college, where hitters aren’t generally exposed to high velocity and see a lot of mistake pitches. It works less well when Brandon Pfaadt is spinning sweepers that teleport across the width of the plate. Esteban also pointed out that fastballs on the inner half or sliders off the plate could trouble a hitter with a swing oriented toward crushing middle-middle mistakes.
Langford, for his part, appeared well aware of the problem.
“We’re working on getting back to that center mass, and not staying back too much,” Langford said in April. “It’s caused me to swing a little more up than I wanted, and I’m leveling out my swing. That’s helping me see the ball better.”
The early results were not favorable. Langford’s average launch angle climbed each month, from 16 degrees in April all the way to 23 degrees in August. Perhaps as a result, he was flummoxed by sweepers and sliders thrown by same-handed pitchers; through August, his wOBA was .234 on these pitches. He was even worse on hard inside fastballs; his .205 wOBA on high-velocity sinkers and four-seamers thrown on the inner half ranked among the worst in the league.
But in September, the swing leveled out. Langford’s average launch angle in September — 11 degrees — was the lowest of any month in the 2024 season. And the results — perhaps coincidentally, perhaps not — followed.
On inside heat, Langford never really adjusted. But he started crushing fastballs left out over the plate as well as hanging breaking balls, staying back long enough to identify spin and punishing mistakes. A good portion of his damage came on swings like this double against Marcus Stroman, lasering sliders at the knees into the right-center field gap:
These improvements coincided with a change to his setup. In April, he was hunched at the moment of the pitcher’s foot strike, looking to my amateur eye more like a slap hitter:
But during his month of destruction, Langford stood much more upright, ready to attack balls at any depth or width.
Langford’s apparent mechanical adjustments, prospect pedigree, and chronologically convenient damage distribution leads to questions about the nature of projections. Prospect evaluators, including our own Eric Longenhangen, were unbothered by his slow start. In his Top 100 Prospects Update in May, as Langford sat sidelined with a hamstring injury, Eric wrote that he expected Langford would “be an offensive star upon his return, and probably pretty quickly,” noting that the “huge tools and plate coverage” remained intact. It was just a matter of adjusting.
In his final month of the season, Langford looked like the offensive star Eric expected. In most cases, a huge month should not be cause for altering a projection. Langford, though, could be an exception.
