Angels prospect George Klassen finds success with improved command

SOUTH JORDAN, Utah – George Klassen looks like he should still be doing homework.

The 24-year-old right-hander has a baby face that betrays none of the mileage on his arm — two and a half seasons of minor league bus rides, a rough big-league debut, a demotion and the kind of quiet, stubborn reinvention that turns fringe prospects into rotation pieces.

Klassen is one of a steady stream of arms the Los Angeles Angels have funneled through Salt Lake on their way to the majors — the Triple-A Bees serving as the final proving ground before the bright lights of Angel Stadium.

For some, the stopover in Utah is brief. For Klassen, it was exactly the reset he needed.

Seven shutout innings for George Klassen against the Astros!

After walking 14 in his first 8.2 MLB innings, he has four walks in his last two starts and a 66% strike rate over those 13 innings

Klassen’s first taste of the majors in April ended with a 13.50 ERA, 10 walks in 4⅔ innings and a flight ticket back to Triple-A.

Four months later, he’s back in the Angels’ rotation — and pitching like a different person. On Aug. 18, Klassen held the Houston Astros to one hit across seven scoreless innings with seven strikeouts, becoming the first Angels rookie to allow one hit or fewer over seven-plus innings since Reid Detmers’ no-hitter on May 10, 2022. He’s 2-1 with a 3.74 ERA since being recalled Aug. 7, and the path from there to here ran directly through Salt Lake.

“You can’t really change what you did in the past or what happened yesterday,” Klassen said. “What can I learn from yesterday that I can put toward today? What can I do today that’ll help me tomorrow? My pitching coach and I always say, instead of taking one big leap, let’s take one small step at a time, and over time, it’s going to add up.”

That philosophy has become the through-line of a career that, despite Klassen’s boyish appearance, has already covered a lot of ground.

A Glove on His Hand

The origin story is almost too perfect.

Klassen was 3 or 4 years old — he doesn’t remember exactly — on a camping trip with his family. It was Lake Michigan. Or the Mississippi River. One of the two. His dad was skipping rocks, and the toddler wanted in.

“I was just beating him,” Klassen said, grinning. “Kept putting a little bit more on it, and I was beating him every time. My mom and dad looked at each other, and they were like, ‘We gotta put a glove on his hand. We gotta see what he can do.'”

So they did. T-ball became town ball. Town ball became Wisconsin travel ball. By high school, Klassen had gone all-in.

“My mom and dad were always in my corner,” he said. “They were always like, if you’re not having fun, don’t do it. They never pressured me and never forced it on me. If I wanted to play, they were there for me.”

Growing up in West Bend, Wisconsin, Klassen spent summers in the backyard pool with his parents, the radio tuned to Bob Uecker calling Brewers games. The Northwoods League’s Lakeshore Chinooks played 10 minutes from his house.

Baseball wasn’t just something he did. It was the background of his childhood.

Fast Track, Rough Landing

Klassen was drafted by the Philadelphia Phillies in the sixth round (193rd overall) of the 2023 MLB Draft after three seasons with the Minnesota Golden Gophers.

He made his pro debut the following year and immediately turned heads, posting a 0.71 ERA and 0.87 WHIP while punching out 57 batters in 38 innings with Single-A Clearwater — earning both a midseason promotion to High-A and an FSL Postseason All-Star nod. With the Jersey Shore BlueClaws, he made five starts, striking out 32 in 21.1 innings.

In July 2024, the Phillies packaged Klassen and lefty-hander Sam Aldegheri in a trade for Carlos Estévez, sending the young hurler to the Angels organization. He finished his first pro season having pitched for four teams, compiling a 3.10 ERA and 135 strikeouts against 46 walks in 93 innings.

Speed has always been the defining feature of Klassen’s professional life — and not just the kind that comes out of his right hand.

“When I was drafted, it was the Phillies in ’23. I got the call, and they told me, ‘Hey, you’re going to be in Florida in three days,'” he said. “When I got traded, I was about to go warm up for my start. They said, ‘Hey, you got traded to the Angels.’ I was in California a day later from New Jersey. It’s just how fast everything moves.”

He opened 2025 with Double-A Rocket City, registering a 5.35 ERA across 24 starts and 102.2 innings before a late-season bump to Triple-A Salt Lake. His final appearance of the year came with the Bees, when Klassen scattered six hits over six frames while striking out eight and walking one.

He returned to Salt Lake to begin the 2026 campaign and needed just one start before the Angels called his number. When scheduled starter Ryan Johnson was scratched with an illness on April 5, the 24-year-old got the nod for his MLB debut against the Seattle Mariners at Angel Stadium.

The notification came at midnight. The game was the next afternoon.

“Our Angels guy called me and said, ‘Hey, you’re starting tomorrow.’ I’m like, it’s midnight,” Klassen said, laughing. “I called my sister, called my girlfriend, called my parents. I was like, ‘Hey guys, I know it’s 2 a.m. where you are right now, but you gotta get on a flight in three hours.'”

He tried his dad first, but there was no answer. Then mom, who was tossing and turning, picked up and went to shake his father awake. His girlfriend was already up, working a night shift. They all made it to Anaheim.

The debut didn’t go as planned.

Klassen walked five in 2.2 innings, allowing three runs (two earned), though he did notch his first career strikeout against three-time All-Star Julio Rodríguez.

Six days later in Cincinnati, he gave up four hits and walked another five on his way to four earned runs in two innings before exiting.

The Angels optioned Klassen back to Salt Lake on April 12. The demotion may have been exactly what he needed.

“I think I put a little too much thought into being pinpoint perfect,” Klassen said. “Like, if I miss my spot by an inch, it’s gonna be terrible. It’s just throwing all those thoughts out, watering it down, and going out there and competing.”

Resetting in Salt Lake

Utah has become a familiar waypoint for Angels prospects on the verge.

The Bees’ roster turns over constantly as arms shuttle between Salt Lake and Anaheim, and for Klassen, the stability of a regular rotation spot at The Ballpark at AFS was the foundation he needed to rebuild.

Through 14 starts with the Bees this season, Klassen owns a 4.38 ERA with 59 strikeouts and 36 walks in 61.2 innings. The walk rate that plagued his big-league cameo has steadily improved and appears to have turned the corner in late June.

Take a bow, George Klassen.

He delivered a quality start in a 3-2 win over Tacoma. Then, on July 1, Klassen put together his best performance of the year: seven scoreless innings, three hits, one walk, and a career-high nine strikeouts in a 4-0 blanking of Las Vegas. He fanned five straight during one stretch and retired 15 consecutive batters.

He parlayed the success into Pacific Coast League Pitcher of the Month honors in July.

Ranked No. 12 on MLB.com’s Los Angeles Angels Top 30 prospects list, Klassen led the PCL in innings pitched (36⅓), strikeouts (38), WHIP (0.99) and opponent batting average (.197). His 38 strikeouts were 12 more than any other pitcher in the league during the month.

Commitment Over Hope

Ask Klassen what his best asset is on the mound, and he doesn’t mention velocity or a particular pitch. He talks about his mind.

“Just not giving in,” he said. “Not thinking this pitch isn’t there, not thinking it’s going to be a bad throw. Just attacking every single time. Throw a pitch. Maybe it wasn’t there. Clear it. Let’s go to the next one. That short memory — just keep stacking good pitches.”

His reset mechanism is as endearing as it is effective. Between innings, if his mind is racing, Klassen draws an initial of one of his pets in the dirt — two dogs, a lab and a border collie, and two cats back home.

“At the end of the day, it’s just a game,” he said. “And if you can think that out there, it just clears everything.”

His pitch mix is straightforward: four-seam fastball, changeup, curveball, and slider. When the situation tightens, he leans on the slider.

Klassen doesn’t obsess over analytics between starts, preferring to trust what he sees and feels during his bullpen sessions.

“You might throw a slider and think, ‘Oh, really good,’ then look at the numbers, and it’s like, that was the worst slider I’ve ever thrown,” Klassen said. “When it feels good and looks good, I take that as a win.”

His start-day routine matches the temperament — no Max Scherzer brooding in the corner, no superstitions, no pregame Snickers bar (not anymore, he clarified). He sleeps in, does a crossword, and plays some ping-pong with teammates.

“If you think about it all day, you’re gonna be tired before the game,” he said.

Just Keep Playing

Klassen is 2-1 with a 3.74 ERA since being recalled on Aug. 7, and for the first time in his young career, he looks like he belongs.

It wasn’t long ago that the baby-faced right-hander was traveling back to Salt Lake with a 13.50 ERA and a bruised finger, wondering if he’d tried too hard to be perfect. The answer, it turned out, was to stop hoping and start committing to each pitch, each day.

When asked what his dreams are — where he sees himself 15 years from now — the kid from Wisconsin who once out-threw his father skipping rocks didn’t talk about Cy Young Awards or World Series rings. He kept it simple.

“I just want to play as long as I possibly can,” Klassen said. “That’s the biggest thing.”

One small step at a time.
