Baseball has always been a sport where confidence is key, but sometimes, that confidence spills over into straight-up delusion. Whether it was talking trash they couldn’t back up or calling their shots one too many times, these players had no shortage of swagger.
Some earned it with their play, others just acted like they did. From trash talkers to bat-flippers to guys who were somehow always right (even when they weren’t), here are the most overconfident MLB players to ever do it.
24. Yasiel Puig
Puig burst onto the scene like he was the main character in a baseball movie. He celebrated singles like walk-off homers and made every play look like an audition for center stage.
23. Rickey Henderson
Rickey didn’t just think he was great—he told everyone he was the greatest of all time. And honestly, how he talked about himself was almost as legendary as the bases he stole.
22. A.J. Pierzynski
No one in baseball loved being hated more than Pierzynski. He carried himself like the most intelligent, toughest guy in the room, letting you know it at every opportunity.
21. Nyjer Morgan
“Tony Plush” was Morgan’s alter ego, and he played like a man who thought he was a superhero. He talked loudly, played flashy, and left behind one of the most chaotic highlight reels ever.
20. David Wells
Boomer never met a moment he didn’t think he could handle. From showing up hungover to throwing a perfect game to openly calling people out, his confidence bordered on reckless.
19. Manny Ramirez
Manny being Manny wasn’t just a phrase—it was a lifestyle. He played the game like he was in his world and acted like it was all going according to his script.
18. Josh Donaldson
Donaldson strutted into every batter’s box like it was a duel and he was the gunslinger. His attitude screamed “I’m the guy,” even when the numbers didn’t always agree.
17. Joba Chamberlain
When Joba-mania hit, you’d have thought the Yankees had found the next Rivera-Clemens hybrid. His fist pumps were legendary, even if his dominance didn’t quite stick.
16. Barry Zito
Zito talked like a Cy Young winner long after the award was a distant memory. His curveball had swagger, but his confidence never wavered—even when his ERA did.
15. Trevor Bauer
Bauer didn’t just pitch—he engineered, analyzed, and antagonized. He walked around like the most intelligent guy in the league and never missed a chance to say it out loud.
14. Jose Canseco
Canseco believed he was the future of baseball—and then tried to tell us everything about the past, too. Whether it was biceps or conspiracy theories, he was never short on self-belief.
13. Milton Bradley
Bradley played with a chip on his shoulder the size of a Louisville Slugger. He was convinced the world was against him—and that he was still the best player on the field.
12. Brian Wilson
With his jet-black beard and postgame antics, Wilson acted like a rock star who just happened to throw baseballs. He backed it up for a stretch, but his over-the-top confidence made him a character straight out of a comic book.
11. Carlos Zambrano
Zambrano pitched like every inning was personal. His confidence bordered on fury, and he always looked like he was one fastball away from challenging the batter to a duel.
10. Pete Rose
Charlie Hustle talked like a legend before he became one. He was loud, brash, and always convinced he was the toughest guy in the room, on or off the field.
9. Eric Byrnes
Byrnes never jogged when he could sprint and never gave a quote without flair. His confidence made him a fan favorite and a clubhouse wildcard at the same time.
8. Reggie Jackson
Reggie didn’t just believe in clutch—he thought he was clutch. When you call yourself “Mr. October,” you better be confident; he made it an art form.
7. Curt Schilling
Schilling pitched with swagger and spoke with even more. Whether it was about bloody socks or politics, he had no doubt he was right about everything.
6. Carlos Gomez
Gomez played every inning like it was Game 7 and every hit like a walk-off. He celebrated, stared down, and chirped with the confidence of a man who lived for the spotlight.
5. David Ortiz
Big Papi’s swagger wasn’t just in his bat—it was in every step, every stare, and every postgame quote. He always knew he was the moment, especially when the moment mattered most.
4. Alex Rodriguez
A-Rod acted like the main character in MLB: The Show, even when stuck in a real-life glitch. From centaur portraits to awkward interviews, he carried himself like he knew he was born for stardom.
3. Roger Clemens
Clemens had the mound presence of a linebacker and the attitude to match. He threw hard, stared harder, and always pitched like he was sending a message.

2. Bryce Harper
Even as a teenager, Harper had the energy of someone who already had a bust in Cooperstown. The eye black, the hair flips, the monster home run trots were all part of the show.

1. Barry Bonds
No one oozed self-assurance like Bond. He stood in the box like the pitcher was lucky to be there, making every swing feel like a mic drop.
