Baseball may seem like a laid-back, pastoral sport, but don’t be fooled – some of its biggest stars have had tempers hotter than a midsummer doubleheader. Whether it’s arguing with umpires, jawing at opponents, or smashing a Gatorade cooler into a fine mist, these players never quite mastered the art of staying chill.
From legendary sluggers to intense pitchers, these guys wore their emotions on their sleeves, for better or worse. Here’s a look at 20 MLB stars who might’ve benefitted from a deep breath or two over the years.
20. Carlos Zambrano
Never one to keep his feelings bottled up, Zambrano’s mound meltdowns were practically part of his repertoire. From heated arguments with umpires to dugout dust-ups, Big Z’s intensity was always on full display.
19. Bryce Harper
Known as much for his fiery attitude as his MVP-level talent, Harper has never been shy about letting his emotions fly. Whether it’s charging the mound or snapping a bat over his knee, Harper keeps things entertaining.
18. Paul O’Neill
The “Warrior” of the Yankees dynasty era, O’Neill didn’t just play the game – he fought it. He’s probably the only guy to ever beat up a water cooler with a baseball bat mid-game.
17. Yasiel Puig
Electric on the field and explosive in the dugout, Puig’s career has been a rollercoaster of highlight-reel plays and unforgettable outbursts. The Wild Horse doesn’t hold back, whether he’s staring down a pitcher or sparking a bench-clearing brawl.
16. George Brett
The infamous Pine Tar Incident alone earns Brett a spot on this list. His wild-eyed sprint toward the umpire after being called out remains one of the sport’s most iconic meltdowns.
15. Milton Bradley
Bradley’s career was a mix of power and volatility, often letting his temper get the best of him. He’s had public blowups with teammates, managers, and even fans, making him a permanent resident on this list.
14. Roger Clemens
The Rocket’s intensity on the mound was legendary, but so were his temper tantrums. Just ask Mike Piazza, who nearly took a shattered bat to the chest during the 2000 World Series.
13. Jonathan Papelbon
No stranger to a heated confrontation, Papelbon’s dugout scuffle with Bryce Harper might be the most memorable moment of his later years. Add in his intense stare and you’ve got a closer who always ran a little hot.
12. Albert Belle
Known for his fearsome power and fierce demeanor, Belle once chased down a heckling fan in the stands. His explosive temper made him one of the most intimidating hitters of his era.
11. A.J. Pierzynski
If there’s a scuffle on the field, there’s a good chance Pierzynski is at the center of it. Known as one of baseball’s great agitators, he played with a chip on his shoulder every game.
10. Lou Piniella
Before he was a fiery manager, Piniella was an equally intense player. He brought the same bulldog mentality to the field, never hesitating to argue a call or get in an opponent’s face.
9. Manny Ramirez
Sure, he was known for being “Manny Being Manny,” but the slugger also had a short fuse. Just ask the Red Sox clubhouse attendant who once found himself in Ramirez’s crosshairs.
8. Jose Bautista
One bat flip changed the trajectory of his career, but Bautista’s passion for the game has always been evident. His infamous punch-up with Rougned Odor remains one of the sport’s most iconic dust-ups.
7. Pedro Martinez
One of the greatest pitchers ever, but also one of the feistiest. Martinez wasn’t afraid to throw hands – or at least throw an aging Yankees coach to the ground in a playoff brawl.
6. John Rocker
Rocker’s mouth got him in just as much trouble as his arm. Known for his controversial comments and over-the-top intensity, he never seemed to find the off switch.
5. Reggie Jackson
“Mr. October” had a flair for the dramatic, on and off the field. His infamous dugout showdown with Yankees manager Billy Martin is still the stuff of baseball legend.
4. Carlos Gomez
One of the game’s most animated players, Gomez’s emotional outbursts often led to benches clearing. His high-energy style of play always seemed one spark away from a fire.
3. David Ortiz
Big Papi’s smile could light up a room, but his temper could clear a dugout. His infamous phone smashing incident is a Hall of Fame-worthy meltdown on its own.
