Two seasons of .211/.270/.324 baseball will test anyone’s patience. Cardinals fans who stuck with Jordan Walker through 2024 and 2025 deserve some credit, because there were stretches — long ones — where it genuinely looked like the 21st overall pick in 2020 was going to become a cautionary tale about tools not translating.
He’s translated.
Walker enters May with 10 home runs, a .308/.373/.583 slash line, and a .956 OPS. Baseball Savant’s statcast page shows a 20.0% barrel rate — 98th percentile — and a hard-hit rate of 58.8% (94th percentile). His average exit velocity sits at 95.5 mph, 91st percentile among all MLB batters. These aren’t the numbers of a hot streak. They’re the numbers of a hitter who changed something fundamental.
That something has a name: Cressey Sports Performance, the offseason training facility where Walker overhauled his swing before 2026. The mechanical changes are specific and trackable. His stance closed from 43 degrees open — an almost exaggerated open setup — to just 10 degrees open, dramatically improving his ability to cover the inner half. His attack angle climbed from roughly 5-6 degrees to 8 degrees. His fly-ball rate nearly doubled, jumping from 22.3% in 2025 to 40.0% now, while his popup rate actually fell from 9.2% to 3.3%. That last part matters: the new loft is quality loft, not weak pop-up loft. FanGraphs shows his wRC+ sitting around 188-191, which puts him in the company of players who are genuinely carrying their lineups.
Walker explained the mental side of the shift in April: “I’m really not thinking about my mechanics and shutting my brain off the best that I can. It’s never possible to shut everything off, but as best as I can — if I can just not think about my mechanics and then just swing when the ball is out there.” Oliver Marmol was direct about what made the difference: “It has more to do with the mechanical changes and less to do with who’s in front of him and behind him.” And on what it took to finally break through, Marmol didn’t sugarcoat it: “Unless he makes the mechanical changes, changes his approach and has the level of preparation of understanding how he’s going to be attacked, none of it matters.”
The plate discipline numbers back the new approach. His chase rate dropped from 34.1% in 2025 to 28.0% this year — six full points — which is why pitchers can no longer expand the zone against him without consequences. Walker explained the mental shift behind it: “The reason I feel like I wasn’t swinging more often at in-zone pitches last season is I was afraid to chase.” That’s a genuinely interesting diagnosis from a 23-year-old. He was so worried about chasing that he was also taking strikes. Close the stance, clear the head, trust the contact — and suddenly the whole plate opens up.
The April 30 game against Pittsburgh was as clean a statement game as you’ll see. Walker homered off Paul Skenes in the first inning of the sweep clincher — a 10-5 Cardinals win — and drove in three runs on the day. Skenes, who gets treated like a demigod by most of baseball, is now 0-5 lifetime against St. Louis. Walker hitting him in the first inning of a sweep is the kind of thing Cardinals fans will be telling people about at the ballpark for years.

NL executives polled by MLB.com named Walker the biggest early-season surprise in baseball — six votes, the most of any player. That’s a meaningful signal. These are people paid to evaluate talent, and they’re surprised. Former Cardinals first baseman Matt Adams put it plainly: “He’s playing the game on both sides of the ball with a ton of confidence. He’s the Jordan Walker that got him here. He’s a fun guy to watch right now.”

The honest caveat is that we’re talking about roughly 25 games. Barrel rates and exit velocity stabilize faster than batting average does, which is why the advanced metrics carry more weight here than the slash line — but the slash line is also very good, so the caveat doesn’t cut as deep as it normally would. What Walker built at Cressey isn’t going away between now and October. The stance is the stance. The attack angle is the attack angle. Whether the league makes adjustments and whether Walker adjusts back — that’s the actual question worth watching. The foundation, though, looks like it was poured in concrete.
