Baseball might be a game of patience, but not every player got the memo. Over the years, some MLB stars have developed reputations for blowing their top at the slightest provocation—whether it’s a bad call, a dust-up at second base, or just a rough day at the plate.
This list is dedicated to those players who never seemed far from a meltdown. From dugout explosions to full-on brawls, these are the guys you wouldn’t want to accidentally brush back with a fastball.
25. Bryce Harper
One bad strike call and Harper’s helmet is already halfway to the dugout. He plays with fire—and occasionally throws some, too.
24. Milton Bradley
Bradley had talent, but his temper was legendary. Umpires, teammates, and even fans weren’t safe from his outbursts.
23. Jorge Posada
The Yankees catcher wasn’t afraid to bark at anyone, especially if he felt disrespected. His fiery presence behind the plate made him a vocal leader—and a ticking time bomb.
22. A.J. Pierzynski
Known as one of the most hated players in baseball, A.J. loved stirring the pot. He never backed down from a confrontation, and sometimes looked like he welcomed one.
21. Carlos Zambrano
Zambrano didn’t just wear his emotions on his sleeve—he blasted them across the entire field. Dugout fights, broken coolers, and endless yelling were his trademarks.
20. Manny Machado
Machado’s fuse is about as short as his jog to first base on a grounder. He’s not shy about spiking a guy or charging the mound if things get personal.
19. Kevin Youkilis
Youkilis had a temper that matched his intensity at the plate. Pitchers who tried to crowd him usually got a mouthful in return.
18. Ian Kinsler
Kinsler had a knack for talking himself into trouble with umps. He didn’t hold back his thoughts, no matter the situation.
17. Brett Lawrie
This guy once spiked his helmet so hard that it hit an umpire. That pretty much sums up his vibe.
16. Albert Belle
Belle didn’t just lose his cool—he incinerated it. From chasing down trick-or-treaters to leveling Fernando Viña, the man was chaos personified.
15. Jonathan Papelbon
Closers are intense, but Papelbon took it to another level. Just ask Bryce Harper, who once got choked out by him in the dugout.
14. Yasiel Puig
Puig brought flair, swagger, and a whole lot of temper. Whether it was a bat flip or a bench-clearing brawl, he was always in the mix.
13. George Brett
Don’t mention pine tar unless you want to see Brett go nuclear. His iconic meltdown is still one of the most replayed in baseball history.
12. Roberto Alomar
Alomar was a Hall of Fame second baseman with a habit of arguing—sometimes to the point of infamy. One heated moment even got him suspended for spitting at an ump.
11. Josh Donaldson
Donaldson plays with an edge—and sometimes falls right off it. He’s been known to chirp at pitchers, umps, and anyone who gets in his way.
10. Shane Victorino
The “Flyin’ Hawaiian” had no problem flying into a rage. He was quick to charge the mound or fire back at a brushback pitch.
9. Vicente Padilla
Padilla was notorious for hitting batters and daring them to do something about it. The dude practically invited mayhem.
8. Billy Martin
Okay, technically a manager—but no list of short fuses is complete without him. Martin’s brawls with umpires, players, and even his own bosses are the stuff of legend.
7. Manny Ramirez
Underneath all the “Manny being Manny” antics was a player who could blow up in an instant. He once slapped a teammate and shoved a traveling secretary.
6. Chris Carpenter
Carpenter was never shy about letting hitters—or umpires—know how he felt. His intensity often spilled over into full-blown fury.
5. Jose Bautista
That bat flip may have made him a hero, but it also put a target on his back. When things escalated, he was usually at the center of it.
4. Gary Sheffield
Sheffield’s swing wasn’t the only thing with violence behind it. He was fiery, confrontational, and rarely held back.
3. Pedro Martinez
Pedro didn’t just pitch with aggression—he carried himself with it, too. He threw at hitters, tossed Don Zimmer, and smiled through all of it.

2. Bob Gibson
Gibson didn’t believe in friends on the field—only opponents. He ruled the mound with intimidation and didn’t hesitate to retaliate.
