Baseball has always been a game of swagger, but some made it an art form. While confidence is key to success, these MLB stars took their self-belief to stratospheric levels and ensured the world knew it.
Whether they were barking at umpires, preening for the cameras, or acting like the world revolved around their batting average, these players didn’t exactly shy away from the spotlight. From dugout divas to mound monarchs, here are 20 MLB stars whose self-importance belonged in Cooperstown.
20. Alex Rodriguez

A-Rod never met a mirror he didn’t like, and he rarely let a camera pass him by. His ego was almost as big as his contract between the on-field antics and off-field drama.
19. Trevor Bauer

Bauer always believed he was the smartest guy in the room, ensuring everyone else knew it. Whether feuds, vlogs, or just being extra, subtlety was never in his playbook.

Harper came into the league with more hype than a summer blockbuster and carried himself like a walking billboard. His confidence was sky-high before he proved anything, and he played like the main character from day one.

Schilling loved the sound of his voice almost as much as his splitter. He pitched like an ace, but acted like the world needed a daily press conference about his greatness.
16. Rickey Henderson

Rickey didn’t just think he was the best—he told everyone, often in third person. His speed was unmatched, but so was his belief in his legend.

Canseco always believed he was baseball’s gift to the world—even when the world begged to differ. He never lacked self-assurance, from his on-field antics to post-career Twitter takes.
14. Manny Ramirez

Manny being Manny wasn’t just a phrase—it was a lifestyle. He marched to his beat, which often included a hefty dose of ego.
13. Reggie Jackson

Mr. October didn’t just thrive in the spotlight; he demanded it. Reggie once said he was “the straw that stirs the drink,” and he wasn’t talking about humility.
12. Josh Donaldson

Donaldson played with a chip on his shoulder the size of a Louisville Slugger. He carried himself like the game owed him something and ensured everyone got the memo.
11. Yasiel Puig

Puig had the energy of a rock star and the subtlety of a fireworks display. Every at-bat felt like a performance, and he was always the headliner.
10. Dennis Eckersley

Eckersley didn’t just close games—he styled on hitters while doing it. With the mustache, swagger, and one-liners, he treated the mound like his personal runway.

Gómez brought flair, fire, and a whole lot of self-confidence to every plate appearance. He celebrated singles like walk-offs and flipped bats like it was his job.
8. Johnny Cueto

Cueto’s windups were part pitch, part performance art. He knew he was entertaining and leaned into the theatrics.

Zito’s curveball was legendary, and he carried himself like a Zen master with a Hollywood agent. His vibes were cool, calm, and entirely convinced of his brilliance.
6. Brian Wilson

Wilson didn’t just close games—he closed them in character. The beard, bravado, and borderline performance art were all peak self-importance.
5. Javy Báez

El Mago played like the game was built around his highlight reel. Every tag, flip, and stare-down screamed, “You’re welcome for the show.”
