We’re Seeing a Whole New Version of Sebastian Walcott

Recently, Major League Baseball has seen an influx of truly special shortstop talents across the league. With superstars like Bobby Witt Jr. and Elly De La Cruz dominating the Major League side, and prospects like Jesus Made and Leo De Vries on the Minor League side, it seems like the sport is entering a golden era for talent at the “six”.

Among the players on the minor league side is Texas Rangers shortstop Sebastian Walcott, a lengthy middle infielder with eye-popping tools. After posting a 126 wRC+ between High-A and Double-A in 2025, he had a ton of buzz surrounding his name heading into 2026.

However, during spring training, Walcott suffered a UCL tear that many thought would end his 2026 season before it even got underway. It was a devastating turn of events, as it kept him off the field and delayed the debut of an offseason of work that had Walcott in position to do significant damage at the dish.

Despite suffering this injury, Walcott made his return to the diamond far ahead of schedule, being activated once again on July 17. Since returning from the injured list, Walcott has looked like a completely new hitter, as he’s added serious impact at the plate and fully transformed his offensive profile.

Walcott is evolving right before our very eyes, and there’s a very good chance we’re seeing a completely new version of him than we’ve previously been accustomed to.

With that version of Walcott already ranking inside the top 20 on our latest top prospects list, the sky could be the limit for the 20-year-old, and it’s all because of a few changes he’s made at the dish.

All stats updated prior to games on Saturday, September 5

Added Impact

For starters, we cannot talk about Walcott’s 2026 performance without mentioning his added impact at the dish. Before this season, Walcott had never slugged more than 13 homers in a single season (2025), and he’s already hit eight through his first 32 games this season, which alone speaks to the improvement he’s made in the power department.

But when we dig a little deeper, we can confirm this power surge through more than just his surface-level output, and the results are incredibly encouraging.

Walcott has already popped exit velocities as high as 115.5 MPH this season (this came by way of a double on July 25th), which is very impressive for any player, let alone a 20-year-old who missed a great deal of time at the beginning of the season.

To help put in perspective just how impressive it is that Walcott reached this threshold, only 18 players in MLB this season have posted a 115.5 max exit velocity or higher. Garrett Mitchell is the only big leaguer to equal Walcott’s max EV of 115.5, and this mark is higher than superstars such as Shohei Ohtani, Mike Trout, Pete Crow-Armstrong, Colson Montgomery, Ronald Acuña Jr., and more.

It doesn’t end there, either. Of Walcott’s hardest-batted balls dating back to 2024, three of them have come during the 2026 season, which again helps us truly appreciate the power he’s gained this season. This somehow becomes even more impressive when you remember that he’s done all of this in just 32 games so far this season.

When examining the rest of his batted-ball data, we begin to see that this increase in power isn’t just limited to his hardest batted-balls of the season. His average exit velocity currently sits at 88.7 MPH, which is a fine place for him to be as a 20-year-old in Double-A. But this isn’t where the real strides have been made.

Firstly, Walcott has seen his average exit velocity against four seamers jump from 90.4 MPH to 92.3 MPH, which is quite a meaningful jump. This same positive step forward is seen in his exit velocity on balls in the air, which has jumped nearly 4 MPH, going from 89 MPH to 92.9 MPH.

Not only is Walcott making more hard contact, but this contact is also more meaningful than it’s been in years past. For example, he’s become an air-pull machine, as his air-pull rate jumped from 35% to 42% this season. His exit velocity is up as well, which has led to more line drives and fewer ground balls, which has helped his output tremendously.

As if all of these numbers weren’t enough proof, his bat speed has also risen, which is yet another great indicator of the change in power he’s undergone this season. Last season, his bat speed barely fell shy of 76 MPH, but in 2026, it’s up over 77 MPH.

As you can see with each one of these metrics, Walcott has significantly improved his power output. Although it’s only been 32 games, Walcott looks like a completely different type of hitter who is now capable of punishing mistakes and making opponents pay for leaving things over the heart of the plate.

A New and Improved Swing

Of course, when a hitter makes these types of strides in their power output, it doesn’t just happen overnight: it’s typically a result of carefully constructed swing changes that better optimize a hitter for launching the baseball and making more consistent, hard contact. In Walcott’s case, this is exactly what happened.

Beginning in his setup, the changes are already quite visible.

Here, the main thing that sticks out is the difference in Walcott’s bat positioning. Last year, Walcott kept his bat over his shoulder in a flatter position, which often led him into poor, inconsistent launch positions through his swing. Without consistently being in a position where he could work straight down to the baseball, he’d often find himself getting stuck, wrapping his barrel around his head, or creating any other type of unnecessary movement.

Now in 2026, Walcott has raised his barrel up above his shoulder, as the end cap is now pointing towards the sky instead of the dugout. Here, Walcott is better able to work straight to the baseball from a consistent launch position, rather than inconsistently trying to load into a position similar to this during his swing.

Also, his barrel has been wrapped behind his helmet much less in 2026, he’s been stuck less frequently, and his bat path has improved overall.

Moving to the load itself, the differences again separate themselves pretty clearly.

In this side-by-side, we’re able to get another look at the difference in barrel positioning and the improvement he’s seen just by raising his barrel. Last season, Walcott’s barrel appears to be a little wrapped, tight, and in a bad position to fire from. However, this year, his barrel is in a better position to fire and work straight to the baseball, cutting out all extra movement.

Also, there’s a pretty significant difference in the load in these two swings. Back in 2025, Walcott was extremely stuck on his back side and often saw his entire lower half collapse as a result of this. He was unbalanced and in a poorer position throughout this entire part of the swing, which you can see in the still frame on the left. From this position, he was unable to correctly coil into his back hip, or really use his lower half much at all, leaving him overly reliant on upper-half rotation.

This year, Walcott has cleaned this up tremendously. It’s a much smaller load that allows him to coil correctly into his back hip and actually generate power from his lower half. From this position, his lower half remains engaged and intact throughout the entirety of his swing, which has been a big part of why he’s been able to generate more raw power.

Lastly, when you look at the beginning of the swing, there’s another great look at the differences between these two swings.

Here, back in 2025, right before the swing, you can see that Walcott is already collapsing and is simply in a poor position to impact the baseball overall. His back elbow is immediately dropping, his barrel is fully wrapped around his helmet, and he’s not really engaged in his lower half.

In 2026, Walcott has again cleaned up a lot of these things. You can see how much his bat path has improved, as he’s no longer stuck behind his helmet, working down to the baseball rather than dropping his elbow, and is generally in a better position to fire.

He’s also far more engaged in the lower half, and although his back hip is opening up a little early, it’s still able to fire so explosively because of how much better he’s coiled and engaged into the lower half. This alone can be make-or-break for power output, and has certainly contributed to his power surge this season. It’s a much, much better launch position that was likely carefully adjusted by the Rangers’ hitting development team.

When you find out that the difference in exit velocity between these two swings was over 2.0 MPH, it begins to really make sense why such little changes matter as much as they do. With all of these little things cleaned up, Walcott can impact the baseball harder than ever before, more regularly than ever before.

Is It Time To Get Bullish?

Seeing the meaningful swing changes and increase in power output Walcott has showcased this season, we’re left with one final remaining question: Is now the time to get bullish regarding his future?

In my opinion, all of these things are consistent with a legitimate power surge, and they help inch Walcott a lot closer to becoming a more complete offensive package in the big leagues. He’s always had plenty of raw juice; it’s just been a matter of putting it together so he can find it more consistently, and he’s done just that in 2026.

Walcott may have elevated his ceiling from being a 20-homer, athletic shortstop at his peak to instead being a potential 30-homer candidate with the same athleticism in his best seasons. This output is so different that it’s almost like we’re examining two completely separate players, rather than the same prospect in different seasons.

This is a budding star, and now is the time to get bullish about what his future may hold before the hype train leaves the station.
