There was a lot of anticipation and intrigue when it came to AJ Smith-Shawver and his return from Tommy John Surgery for the Atlanta Braves in 2026. Considering how much flux the backend of Atlanta’s rotation went through in the previous season, there was a clear opportunity for anybody who wanted to grab onto that role.
AJ Smith-Shawver got that opportunity once he eventually returned in July. So how did that go for him? It’s time to find out.
How Acquired
The Braves selected Smith-Shawver with the 217th overall pick as their seventh-round draft choice in 2021. He skyrocketed through the system in 2023, speedrunning three minor league levels and eventually making his debut in June. Despite, or perhaps because of, his rapid ascent, Smith-Shawver has yet to throw over 45 big league innings in any given season.
What were the expectations?
One of the reasons why Smith-Shawver was unable to clear that 50-inning threshold was because he had Tommy John Surgery in June of 2025, which meant that he’d have to wait a full calendar year before even getting ready to make his return to the mound. As such, the hope was that Smith-Shawver could simply get healthy and hopefully improve upon a 2025 campaign where he showed some flashes of brilliance while still having the typical rollercoaster experience that most rookies and young pitchers experience upon breaking through to the big leagues.
We all know that recovery from this type of thing isn’t exactly a linear or easy process — just ask Spencer Strider and Spencer Schwellenbach about the elbow issues that they’ve both been dealing with for the past couple of seasons. Still, it wasn’t crazy to hope that AJ Smith-Shawver could eventually make a bounce back and become a valuable part of Atlanta’s rotation.
Performance-wise, Smith-Shawver had an 88/115/115 line in 74 career innings before the 2026 season. His 2023 and 2024 were comparatively rougher, but 2025 looked much better at 92/96/105. It was hard to know exactly what to expect given the long layoff and rehab from major surgery, but ZiPS saw him as an above-average-but-very-short-stint starter (about four innings a start, but 1.1 WAR in 80 innings) as its point estimate — basically a slight improvement over his small-sample 2025.
2026 Results
Smith-Shawver made about a month’s worth of official rehab starts, but once July 29 rolled around, he returned to the big league roster for a day as the Braves called him up as the 27th man for a doubleheader against the Mets. He turned in the sort of start that had folks across Braves Country clamoring for him to stick around — even though he was always bound to return to Gwinnett due to the 27th-man rule. Despite a somewhat underwhelming line of just 4 1/3 innings pitched with a 4/2 K/BB ratio, Shawver’s velocity (on his four-seamer, especially his four-seamer) looked impressive, his stuff was lively and he had also added a sinker and a cutter to his arsenal — giving him a very interesting tool box of six pitches to work with.
Smith-Shawver eventually got his chance to join the rotation for real once he got called up ahead of a start on August 19 against the Twins and while his stuff looked lively as usual, this time he was once again unable to make it through the fifth inning in an efficient manner. In fact, Smith-Shawver only ended up making two appearances where he pitched at least five complete innings — and one of those appearances was in long relief after Reynaldo López made (what turned out to be) his final start of the season.
That five-inning relief appearance on September 14 was Smith-Shawver’s first apperance out of the ‘pen and he proceeded to make three more appearances in relief during the final month of the season and eventually made an appearance in the NLDS. That NLDS appearance didn’t go well, as he wound up giving up a two-run dinger to Kyle Tucker and a solo shot to Max Muncy (both in the same inning) that basically gave the Dodgers enough breathing room to take the game on home.
Ultimately, Smith-Shawver finished with a 6.61 ERA (157 ERA-), a 6.00 FIP (145 FIP-), and a 5.17 xFIP (123 xFIP-) with a drop in strikeout rate (18.8 percent compared to 21.9 percent in 2025) and an increase in walk rate (from 10.9 percent in 2025 to 11.1 percent in 2026). He didn’t qualify for a bunch of the usual MLB Percentile Rankings that Baseball Savant provides but if he did, a lot of his categories would’ve been in the blue instead of the red. Needless to say, Smith-Shawver didn’t exactly hit the ground running upon his return to the bigs from Tommy John surgery, and “earned” -0.2 fWAR for his efforts.
What went right?
Well, his velocity is still good after returning from Tommy John surgery and that’s always a positive. His four-seam velocity was back at 96 mph and his sinker was clocked at an average of 95.1 mph. Again, the stuff that he had on display during his 2026 debut against the Mets was encouraging to see and it sure seemed like AJSS had something to really build upon as a starter based on that first impression back.

Also, if that five-inning relief appearance against the Cubs qualified as a start then this would’ve been Smith-Shawver’s best “start” of the season. The Braves were definitely in need of having any starter who could give them innings while only giving up around a couple of runs and the Braves gladly would’ve taken that had it been a start.
Meanwhile, his most encouraging appearance as a reliever came on September 20 against the Astros, which is when he faced seven batters over two innings and only gave up a hit while striking out four batters. It was a very solid appearance during the divisional-clinching win for the Braves in Houston and it was the type of outing that makes you think “Hey, maybe there’s something here with this guy as a reliever.” The Braves certainly thought so, but it was kind of a mixed bag in the end — his next relief outing was pretty bad, and he gave up a homer while striking out three of the five batters he faced in his final tune-up. And then, well, the one in the playoffs didn’t go very wellk.
His splitter was a pretty effective pitch, as he racked up a whiff rate of 31.3 percent and a Put Away percentage of 15.8 percent and 16 of his 27 strikeouts on the season came from that pitch alone. It was clearly his best pitch and it’s clearly the one that he should throw a bit more of going forward.
What went wrong?
AJ Smith-Shawver was just unable to get really deep into games as a starter. In every one of his six long appearances this season, he walked at least two batters and walked at least three in four of those appearances as well. If he walked a batter then that guy usually came around to score. It was either that or his propensity to give up the long ball. While his four-seamer only had a .209 Batting Average against it (along with a .216 xBA), whenever hitters did catch up to his heater, they usually didn’t make a mistake with it. He gave up seven homers all season and four of them were against his heater. Opposing batters slugged .512 against his four-seamer (with an xSLG of .500). He was unable to get a lot of whiffs with it, either. When the pitch you lean on that much is getting hit that hard, it’s difficult to have a lot of success.
Smith-Shawver’s start on September 8 against the Rays was the end of the road (at least in 2026) as a starter and it was basically a single-game example of everything that’s been ailing Smith-Shawver at the big league level right now. He was charged with five hits, he walked two batters, two of those five hits were dingers (against a Rays team that, while excellent on offense, didn’t hit for a ton of power in 2026) and he only lasted 3 1/3 innings. He was unable to get deep into a game, it was his shortest start of the season, and Smith-Shawver found himself heading to the clubhouse after having a largely inefficient night on the mound.
Overall, Smith-Shawver found it hard to rack up strikeouts, he walked a lot of batters, he got hit decently-hard when batters did catch up with his stuff and he got barreled-up on a semi-regular basis. Fundamentally, he posted an xFIP- north of 100 in four of his five starts (well north of 100 in three) — or five of six if you include the five-inning relief appearance. It wasn’t a case of being unlucky or anything, he just wasn’t doing the fundamental business of striking guys out and not walking them well at all. That’s not a recipe for success as a starter, which explains why the Braves decided that the best place for Smith-Shawver going forward towards the Postseason was the bullpen. They just couldn’t afford to have him try to figure it out as a starter while they were holding on to the lead in the NL East and against playoff-caliber lineups in the Postseason.
One additional cruel twist of fate: above, it was listed that his xFIP was below average in every longer-stint outing but one. That one where it wasn’t? It was his worst start by WPA of the year, as, despite the better pitching quality, the Nationals dumped four runs on him and the defense thanks to walks and seeing-eye singles in the second, and then added a homer in the third. Welp.
2027 Outlook
AJ Smith-Shawver will be 24 heading into next season and when you combine his young age with the lack of mileage (when it comes to innings, at least) on his arm, it sure feels like he could get another shot at starting for the Braves once Spring Training rolls around (whenever that may be). He’s got the velocity on his four-seamer that can play but he still has yet to develop it into a truly effective pitch. His splitter is there but everything else still needs a bit of work, as evidenced by the high walk rate and the lack of strikeouts that he was able to get on a consistent basis. Something kind of amusing is that Smith-Shawver didn’t directly struggle with either pitch shape or command — he largely threw his four-seamer and splitter to the same spots over and over. But, those spots just weren’t very good in practice, largely because his splitter tended to miss the zone on the low armside corner. If he fixes that and has that splitter actually fall in for a strike, and things get a lot more annoying for batters, but it was easy to wait him out in 2026.
Early projections aren’t quite so sanguine about Smith-Shawver as they were before he made his return. He’s now targeted as a below-average bulk guy or swingman, even falling short of the “assume everyone is a fourth starter until they show otherwise” heuristic. He’s got some work to do, basically.
Assuming the Braves don’t add to their rotation outside of the organization heading into next season, Smith-Shawver should get an opportunity to make the Opening Day roster as a starter. Maybe with a full (and potentially extended) offseason to figure things out, Smith-Shawver can come back and finally really get rolling with his career. Again, he’s young and it still feels like he’s a bit of a rookie since he hasn’t really had an extended stint in the bigs quite yet. Maybe we’ll see him get that chance and embrace it in 2027. We’ll see what happens.
