As a participant’s physique adjustments over time, the identical actions he used to make could not work properly for him anymore. Adjusting to those adjustments (or not) will make or break his profession. These adjustments have been particularly stark for Giancarlo Stanton. The 35-year-old slugger serves as an attention-grabbing case for observing how nice hitters can alter their swings over time to regulate to their altering bodily attributes.
Stanton had a 116 wRC+ in 459 plate appearances in 2024 – the fifteenth season of his profession. That’s practically similar to the 118 mark he set throughout 396 plate appearances as a rookie in 2010. The distinction between Stanton then and now, although, is night time and day. Let’s check out Stanton at age 20 to get an concept of what his swing was like throughout his first main league season:
Open stance, non-neutral shin angle, slight hand row. None of this stuff are at present current in Stanton’s swing. None. When he got here up, he seemed like an uber-athletic NFL tight finish. He might run properly, transfer fluidly, and was twitchy sufficient to have a bit of additional motion in his swing (in comparison with current years) and nonetheless have success. Yeah, he struck out over 30% of the time in his rookie marketing campaign, however he was nonetheless studying massive league pitching. He boasted a 141 wRC+ the next season with a really comparable swing. It wasn’t till his third season the place there was an apparent change. This was when Stanton confirmed what he was actually able to on the plate (and when he began going by Giancarlo):
Now that’s what I’m speaking about. These are actually Stantonian homers right here. In 2012, Stanton raised his wRC+ to 158, delivering 5.1 WAR in simply 123 video games. He cemented himself as one of many scariest sluggers within the recreation, and far of that must be attributed to his mechanical changes. He modified his stance to a impartial place and raised his palms up a substantial quantity. From this level on, his palms would keep in the next slot. His hand row from the earlier two seasons all the time introduced him to the next level than the place he began in his setup. As a participant with 80-grade energy, he didn’t actually need that additional motion to create pressure. Relying in your physique sort (arm size, higher physique flexibility, and so forth.), swinging a flat bat from a excessive slot makes it simpler to get your bat on airplane. Since he wasn’t the kind of hitter who varies his shoulder airplane all that a lot, it was a logical change to simplify his method.
Even with these adjustments, we’re nonetheless fairly far off from the place Stanton has been over the previous couple of seasons. He maintained these mechanics all through 2012 and 2013. Nonetheless, throughout this time, well being grew to become a problem. He missed time in each of those seasons for knee, stomach , ankle, thigh and shoulder accidents. With out biomechanical knowledge, we will’t definitively say these accidents compelled his physique to vary and/or he needed to regulate his swing to compensate for his compromised well being, however my goodness, these are accidents nearly from head to toe! It wasn’t till the 2014 season that Stanton performed over 140 video games in a single season. And unsurprisingly, he got here into that 12 months with one other modified setup:
That is the primary time in his profession the place we noticed Stanton slim his stance. I’m theorizing right here, however taking away motion might have had two advantages for him: Much like my level earlier than, he’s so robust that he by no means actually wanted to maneuver all that a lot to create energy, and fewer motion would give him a greater shot at making contact. Second, by narrowing his stance and never crouching as a lot, he would put much less stress on his physique. He ended this season with a 161 wRC+, the very best mark of his profession. He additionally remained wholesome till the center of September, when he was hit within the face by a pitch that prematurely ended his season.
The narrowed stance stored working for him in 2015. Throughout his 74 video games to start out the 12 months, he scorched 27 dwelling runs — a full-season tempo of 58. However on June 26 — his 74th recreation — he broke his hamate bone swinging sooner or later throughout his ultimate two at-bats, each strikeouts, and missed the remainder of the season.
The one factor about Stanton’s swing that he has by no means actually reconciled is that he doesn’t decelerate a lot. I believe this can be a massive motive why we see such egregious whiffs from him. As soon as he will get began, there isn’t a slowing down. It additionally comes with some added threat of harm. That is such a violent swing, and his physique bears the brunt of that pressure as a result of he doesn’t have the brakes in place to come back to a managed cease.
Though he was wholesome to start out the season in 2016, it was clear the harm had compromised him. By the tip of the 12 months, he’d utterly gotten away from the setup that he’d had a lot success with earlier than the hamate harm. In truth, he returned to an analogous stance that we noticed from him early on in his profession:
Ahead lean, barely open hips, and extra knee bend. Sound acquainted? That’s as a result of that is basically rookie 12 months Stanton, not the nice hitter he was in 2014-2015. His efficiency additionally reverted again to the place it was in 2010; his 118 wRC+ in 2016 was similar to his mark as a rookie. It is smart, then, that he ditched this setup in 2017. Closed stance Stanton has entered the chat:
Stanton didn’t shut his stance off till about June, however he didn’t run it again the primary few months with the stance he used throughout his down 2016 season. He got here into 2017 with the identical stance he had in 2014-2015, when he was raking. However from the summer season on, he closed issues up, ending the season with 59 dwelling runs and profitable NL MVP. It was a particular run that utterly took off on account of one other mechanical change – most likely crucial of his profession.
Stanton was traded to the Yankees following the 2017 season and confirmed up with the identical actual setup, and for good motive. After struggling massive trip of the gate, he ended up with a 128 wRC+. Not nice however nonetheless excellent. He was wholesome for just about your complete season too, enjoying in 158 video games. Then in 2019, the accidents piled up. After a knee harm that stored him out for nearly your complete 12 months, he returned within the playoffs and sustained a quad harm. Then it was hamstring harm that restricted him to 23 video games through the shortened 2020 season. Over the 2 years, he performed in a complete of 61 common season video games.
Not like different occasions in his profession, Stanton’s accidents in these seasons didn’t result in a mechanical overhaul. At this level in his profession, he knew what the perfect model of himself seemed like. If he might get his physique again to feeling wholesome, it made sense to not undergo any massive adjustments. And in 2021, that labored out properly. He swatted 35 homers in 139 video games and completed with a 138 wRC+. He suffered a minor quad pressure early within the season, however apart from that, he was wholesome all 12 months.
Although he missed 10 days with a minor calf pressure in late Might/early June, Stanton was additionally principally wholesome for the primary half of 2022, and he hit properly sufficient to make the All-Star crew (133 wRC+ through the first half). However then the decrease physique accidents returned, and this time they had been even decrease than earlier than. He made it three days into the second half earlier than touchdown on the IL with Achilles tendonitis. He missed simply over a month, and when he got here again in late August, it took him about two weeks to get going. He additionally had a minor harm scare when he fouled a ball off his foot on September 5; he wasn’t within the lineup for the Yankees’ subsequent 4 video games, although he did pinch hit in two of them. He caught hearth upon returning to the lineup on September 10, posting a 133 wRC+ with seven dwelling runs over his ultimate 79 plate appearances of the common season.
Nonetheless, these specific accidents represented a brand new problem for Stanton. As a closed-stance hitter, he’s way more reliant on his connection to the bottom, making these repeated accidents from the ankle downward particularly regarding. Not solely does he should regain his power, however he additionally has to determine easy methods to transfer in house and work together with the bottom. This will get harder for gamers as they age and the accidents compound. The factor about Stanton, although, is he has all the time been keen to tweak his mechanics. Nonetheless, he wanted to hit all-time low earlier than deciding to go away from the setup that he’d had a lot success with for therefore lengthy.
Well being was an issue for Stanton once more in 2023. He strained his hamstring in April and missed nearly two months. Upon his return, he was far off from his diminished 2022 kind, when he completed the 12 months with 113 wRC+, which to that time was the worst mark of his profession. His 86 wRC+ to finish the 12 months was bleak. He stayed wholesome after his return, however the terrible efficiency introduced up the query: Was this simply an excessive amount of for him to beat? For Stanton, the reply was to do what he had completed so properly for his complete profession. He made some extra adjustments, this time to his mechanics and his physique.
There was quite a lot of dialogue round Stanton’s changes at the start of 2024, together with this complete look from Jay Jaffe. Briefly, the principle level was that he slimmed down (rather a lot!) and shifted nearer to the impartial setup he had from 2014 and 2015 somewhat than the intense closed stance he had employed starting in June of 2017.
This goes again to the discuss matching your swing to your bodily attributes. Stanton has handled so many decrease physique points over the past 5 years, they usually have impacted what he can do bodily. He couldn’t maintain the identical motion sample within the closed stance along with his present physique, so he went to an analogous model of the swing that his physique might deal with. His common season nonetheless wasn’t nice, nevertheless it was a serious step up from the 12 months earlier than. And when you think about the present he placed on in October, it’s secure to say his adjustments labored fairly properly general. For a final look, let’s see the place he stands as of October, from a mechanical perspective:
No matter your opinion is of Stanton’s profession, how he initiatives for the remainder of it, or something associated to that, there isn’t a denying that what he has completed all through the final 15 years has been exceptional. There aren’t many hitters who can change as a lot as he has and nonetheless have success. An enormous a part of being an important baseball participant is making changes. Stanton has completed that extremely properly for a protracted, very long time.
