In baseball, confidence is key, but sometimes, that confidence borders on full-blown icon behavior before the resume fully matches. From struts around the bases to premature celebrations and postgame quotes straight from a movie script, these MLB players walked like legends before they ever made it to Cooperstown (or even an All-Star Game).
Some eventually backed it up. Others, well, they’re still working on it. Either way, these are 20 MLB stars who acted like icons before earning it.
20. Hunter Greene

Greene entered the league with a triple-digit fastball and the swagger to match. Despite the slow results, he looked like a future ace from day one.
19. Jo Adell

Adell had all the tools, the prospect hype, and the social media presence of a star. But he played like a rookie figuring things out—which, to be fair, he was.
18. Alec Bohm

Bohm’s confidence at the plate and in front of a mic made it seem like he was a decade-long vet. Then he had to win the fans back after saying he hated playing in Philly.
17. Jazz Chisholm Jr.

Jazz plays the game with flash, flair, and enough swag to fill a stadium. The numbers haven’t always kept up with the drip.
16. Triston Casas

Casas stretched like a yoga instructor during pregame warmups and carried himself like a clubhouse leader from day one. It was bold energy for a guy still trying to hit above .250.
15. Jarred Kelenic

Kelenic showed up with major league confidence, but the bat didn’t make the same entrance. He eventually figured it out—after some minor league detours.
14. Jonathan India

India’s rookie year had him acting like a franchise cornerstone. The Reds sure hoped so, even if his play since hasn’t quite screamed perennial All-Star.
13. Michael Kopech

With that hair, heat, and attitude, Kopech immediately gave off superstar vibes. But durability and consistency didn’t follow as quickly as the attention did.
12. Bobby Dalbec

Dalbec took swings like Aaron Judge and carried himself like a future MVP. Unfortunately, his strikeout numbers did most of the talking.
11. Clint Frazier

Frazier rocked custom cleats and big-league swagger in the Bronx long before his place in the lineup was secured. New York fans remember the attitude more than the stat line.
10. Nicky Lopez

Lopez had Gold Glove-level confidence from the jump. But early on, he was primarily a glove-first guy with a highlight reel longer than his batting average.
9. Luis Rengifo

Rengifo has always acted like he belonged in the spotlight. But until recently, the stats were more role player than rising star.
8. Tyler O’Neill

O’Neill showed up looking like a bodybuilder and playing like a guy who thought he could hit 40 home runs. The power was real, but the whole package hasn’t always stayed on the field.
7. Harrison Bader

With his flowing hair, sunglasses, and Gold Glove attitude, Bader always looked like a star. The bat, though, often needed a bit more catching up.
6. Josh Naylor

Naylor’s celebrations are loud, proud, and impossible to ignore. That energy was there even before the numbers started catching eyes.
5. Brendan Rodgers

Rodgers was tabbed as the next big thing in Colorado, and he carried himself like it. But it’s been a long, winding road to anything close to consistent production.
4. Joey Gallo

Gallo hit moonshots and acted like a power-hitting legend from the jump. The only problem? He either hit it 450 feet or missed it completely.
3. Akil Baddoo

Baddoo burst onto the scene like he was writing a Hollywood script. He celebrated like a star, but sustaining it has been a different story.

2. Fernando Tatis Jr.

Tatis was a human highlight reel and fashion icon before playing a full season. Suspension aside, at least he’s got the talent to back it all up now.

1. Yasiel Puig

Puig exploded onto the scene with charisma, cannon throws, and bat flips galore. From day one, he acted like a megastar and lived up to it for a while.
