Baseball might be a team sport, but sometimes one bad apple can spoil the whole bunch. Whether it’s endless drama, public feuds, or just an all-around toxic vibe, these players made more headlines for turmoil than teamwork.
Some of them had undeniable talent, but their impact in the locker room was anything but positive. From locker room outbursts to teammates begging for trades, these are 20 MLB clubhouse cancers that truly shook their teams.
20. Brett Lawrie

Lawrie brought energy, sure, but it often crossed the line into chaos. His wild personality and inconsistent focus wore thin on teammates and coaches alike.
19. Vicente Padilla

Padilla had a reputation for being difficult both on and off the mound. Even his own teammates seemed unsure of when he might throw at someone—or why.
18. Yasiel Puig

Puig was electric on the field but erratic behind the scenes. His antics in the clubhouse made him a lightning rod for controversy in multiple cities.
17. Matt Garza

Garza was known for fiery arguments and finger-pointing, often clashing with teammates. He wasn’t afraid to call people out publicly, which rarely goes over well.
16. A.J. Pierzynski

Pierzynski was one of the most disliked players in the game—and not just by opponents. Teammates often found his abrasive style just as irritating as rivals did.
15. Milton Bradley

Bradley’s issues followed him to every team he joined. Explosive confrontations and off-field problems created a constant cloud of tension.
14. Carl Everett

Everett had strong opinions and wasn’t shy about sharing them—often loudly. His disagreements with teammates and management made him a clubhouse headache.
13. Tommy Pham

Pham always speaks his mind, but sometimes that honesty spills into hostility. Whether it’s slapping a guy over fantasy football or calling out teammates, he keeps things spicy in the worst way.
12. Manny Ramirez

Manny being Manny was fun—until it wasn’t. His aloof attitude and frequent distractions often clashed with team chemistry.
11. Jeff Kent

Kent had a Hall of Fame-worthy bat and an ego to match. His frosty relationships with teammates (including a certain left fielder) became legendary.
10. Jonathan Papelbon

Intensity is good until it leads to choking a teammate in the dugout. Papelbon’s fiery demeanor often burned bridges instead of motivating the room.
9. Kevin Brown

Brown was dominant on the mound and difficult everywhere else. Known for moodiness and clubhouse blowups, he wasn’t exactly beloved by peers.
8. Barry Bonds

Bonds’ talent was off the charts, but so was his attitude. The icy vibes in the Giants’ clubhouse often revolved around his diva behavior and demands.
7. Josh Donaldson

Donaldson brought swagger—and sometimes too much of it. Multiple teams grew tired of his confrontational energy and vocal criticisms.
6. J.D. Drew

Drew didn’t say much, and that was part of the problem. Teammates often questioned his passion and commitment, creating a cold and disconnected locker room presence.
5. Jose Canseco

Steroid confessions, wild accusations, and nonstop attention-seeking made Canseco a clubhouse nightmare. He was more focused on headlines than harmony.
4. Nyjer Morgan

Morgan’s alter ego, “Tony Plush,” was entertaining until it wasn’t. His outbursts, fights, and over-the-top antics wore out welcomes quickly.
