Walker Buehler is officially back in a big-league rotation, but it’s not with the team that made him a household name. After a rocky 2025 that saw him bounce from Boston to Philadelphia, Buehler has landed with the San Diego Padres. It’s a move that feels like classic A.J. Preller—high-risk, high-reward, and perfectly timed for a rotation that’s currently held together by duct tape and hope.
The Padres officially added Buehler to their 40-man roster this week, cementing his spot for Opening Day 2026. If you’re a Padres fan, you should be cautiously ecstatic. If you’re a Dodgers fan, seeing "Butane" in brown and gold probably makes you want to throw your remote. Either way, this isn't just another veteran signing. It’s a career-defining crossroads for a guy who was once the most feared right-hander in the National League.
The long road back from the surgeons table
You can't talk about Buehler without talking about the elbow. Most pitchers struggle to return from one Tommy John surgery. Buehler is trying to defy the odds after his second. When he finally returned to the mound in 2024 with the Dodgers, he wasn't the same guy. The velocity was mostly there, but the "stuff" was missing. His 5.38 ERA that year was a far cry from his 2.47 mark in 2021.
Last season didn't provide much comfort. He started 2025 in Boston, where he got tagged for a 5.45 ERA over 22 starts. The Red Sox eventually gave up, leading him to a late-season stint with the Phillies. While he showed flashes of brilliance in Philadelphia—going 3-0 with a much improved 3.17 ERA over his final nine appearances—the market was still cold this winter.
That’s how he ended up signing a minor-league deal with San Diego in February. He bet on himself, turning down guaranteed Major League offers elsewhere because he believed the Padres’ environment and Petco Park’s pitcher-friendly dimensions were his best shot at a true "return to form."
Why the Padres needed this more than anyone
San Diego’s rotation is currently a bit of a mess. Joe Musgrove is recovering from his own UCL surgery performed late in 2024. Yu Darvish is on the restricted list. Matt Waldron and Griffin Canning are on the shelf. Without Buehler, the Padres were looking at a rotation that relied far too heavily on Michael King and Nick Pivetta to carry the load.
Buehler didn't just stumble into this job; he took it. He dominated this spring, posting a 3.09 ERA and a 1.20 WHIP over 11.2 innings. Most importantly, he struck out 13 batters while only walking four. For a guy whose primary struggle post-surgery has been command, those numbers are a massive green flag.
He looks like he’s finally trusting his delivery again. His "three-part" delivery is famously complex, relying on precise timing. When that timing is off by a millisecond, his pitches lose their bite and end up in the bleachers. This spring, the bite was back. His latest outing against the Giants—five scoreless innings with seven strikeouts—was the most "Ace-like" he has looked in three years.
What the 2026 version of Buehler looks like
Don't expect the 2021 version of Walker Buehler to walk through that door. That guy threw 200+ innings and finished fourth in Cy Young voting. The 2026 version is a different animal. He's 31 now. He’s more of a "pitcher" than a "thrower."
- The Arsenal: He’s still leaning on a deep bag of tricks—four-seamer, cutter, knuckle curve, and sinker.
- The Velocity: Expect him to sit 93-95 mph rather than the 97-98 mph of his youth.
- The Mindset: He’s pitching for his career. This is a one-year "prove it" situation where he earns $1.5 million base with up to $2.5 million in bonuses.
The Padres aren't asking him to be the best pitcher in baseball. They just need him to be a reliable mid-rotation starter who can give them 150 innings of league-average or better ball. If he does that, the Padres stay in the NL West race. If he recaptures even 80% of his old self, they just got the steal of the century.
The risk factors nobody is talking about
Honestly, it could still go south. Second Tommy John recoveries are notoriously non-linear. One day you feel like Greg Maddux, the next day your arm feels like a wet noodle. His walk rate over the last 200 innings is near 10%, which is dangerously high for a guy who doesn't strike out 11 per nine innings anymore.
Petco Park will help mask some of those issues. It’s a cavernous park that kills fly balls, which is great for a pitcher who has struggled with the long ball recently. But Buehler still has to find a way to navigate through the heart of lineups without the elite "swing-and-miss" stuff he used to rely on.
If you’re looking for a reason to be optimistic, look at his final month in Philadelphia. He started eating innings and keeping the ball in the yard. He’s a big-game pitcher with a World Series ring and a mountain of postseason experience. You can't teach the "fire" he brings to the mound, and the Padres' clubhouse—often criticized for lacking a certain edge—needs exactly that.
Keep an eye on his velocity in the third and fourth innings of his first few starts. If he's holding 94 mph deep into games, the Padres have found their missing piece. If he drops to 91-92 mph after 50 pitches, it's going to be a long season for the San Diego faithful.
Watch his first start against Detroit on March 26. It won't tell us everything, but it'll tell us if the "Butane" is truly back in the tank. You should probably check your local listings and clear your schedule for that one.
Next Steps for Fans:
- Check the Padres' updated 40-man roster to see who was moved to make room for Buehler.
- Monitor Buehler's fastball velocity during the first two innings of the Opening Series to gauge his physical ceiling for the month.
