There are so many reasons for a fan to love or hate a player. Rarely is a baseball player so widely hated that it becomes a communal thing for fans to come together on. That being said, we're going to go over some of the most hated MLB players in history.
Don't lose this article. Enter your email below, and I'll send it to you right now. Plus, we'll send you other unbelievable stories from baseball's past.
Now it's hard to really have an entire fandom against a single player, so I know that you will probably have at least a little bit of love for one or more of these entries. I'm going to have to go with the crowd, though, and describe how each of these players irked the likes of many.
11. Ty Cobb: Baseball’s Most Notorious Villain
Ty Cobb was one of baseball's first villains. His stats now outweigh the way he played, as we are so far removed from his career that there are fewer who have lived to tell his tale.
There is an unwritten rule in modern baseball not to slide with your spikes hurtling towards the shin of an opposing fielder. That's what Ty Cobb did on a daily basis. He was so infamous for it that it has overshadowed his penchant for violence and racist beliefs. He was probably a real sight to watch play on a daily basis from a positive and negative point of view.
10. Barry Bonds: The Controversial Home Run King
I know there are some obvious Barry Bonds fans who will be reading this, so I have to say I respect him as a player. But, like pretty much everyone on this list, his negative association has faded a bit the longer we get away from his final season.
On the other hand, there are still many who don't consider him the all-time home run leader. Those critics were very loud even when he was still playing. Only time will tell if the Hall of Fame agrees or not.
9. Pete Rose: Charlie Hustle’s Fall From Grace
Pete Rose has been a pariah in baseball for the longest time. His gambling on the game brought an almost unanimous hatred towards the Hit King. But again, as he got older, more fans gravitated back towards him as the lifetime ban seemed to go on for too long.
The ban actually did last until the end of his life, as he passed away in 2024. So one can only wonder if the Veterans Committee will give the ultimate forgiveness in baseball and clear him for entry into Cooperstown.
8. John Rocker: Baseball’s Most Notorious Bigot
This is one where fans have such a different opinion than some players. John Rocker was one of the best closers in baseball in 1999, as he was closing the door for the Braves. Then a Sports Illustrated article came out that revealed absolutely abhorrent comments that he made towards the people of New York City.
He was rightfully shamed and didn't have much of a career following that. However, there have been some former teammates of Rocker who have gone after the Sports Illustrated writer, saying that it was basically a hit piece to ruin Rocker's career. Luckily, today we don't really have to talk about this controversial player much, as his career ended before he was able to accomplish anything huge.
7. Albert Belle: Baseball’s Angry Man
Albert Belle was one of the most explosive players in MLB history. I say that because it has a double meaning. Baseballs would absolutely explode off of his bat, but also many other things would explode inside the dugout, including his temper. Sometimes that would lead to broken bats or other broken equipment. Other times, it led to him trying to use a corked bat in a game to cheat his way to victory.
His anger issues and antics got tiresome for even the fans of the teams he was playing on. I'll say that we're lucky his career didn't last much longer than a decade.
6. Roger Clemens: The Rocket’s Tarnished Legacy
There are a lot of moments when Roger Clemens was universally loved and respected. In fact, there were so many fans who idolized him that it makes it sad to know how it has ended. The Rocket had some help to put extra juice behind his fastballs, and that put a big stain on the way he has been looked at since his retirement.
I'd even go as far to say that he has been thought of far less than Barry Bonds as a candidate for the Hall of Fame even when his number of Cy Young Awards supersedes any other pitcher in history.
5. A.J. Pierzynski: Baseball’s Ultimate Agitator
Here is a player who welcomed the hate. A.J. Pierzynski had a solid career that saw some good successes. It was just the attitude that he played with and spoke with that rubbed fans the wrong way. To put it shortly and bluntly, A.J. Pierzynski is a loudmouth. He always has, and he always will be.
Since retiring, though, he has kind of used that to his advantage. The perception of him has turned the corner a bit, with fans liking his personality on baseball podcasts in current times. That goes to show that what was once a hated attribute can become the most useful one.
4. Alex Rodriguez: A-Rod’s Fall From Grace
It's interesting that I don't even want to say that Alex Rodriguez has been hated mostly for his connection to the steroid scandal. It seems that his personality has actually taken precedence among fans. Since retiring, he has been in the limelight, becoming an owner of sports teams and an analyst on TV.
It seems that his essence and aura have brought about a sort of smugness that fans have come to loathe. To this day, Rodriguez is booed in every stadium he walks into, and it doesn't seem to be going away anytime soon.
3. Manny Ramirez: When “Manny Being Manny” Went Too Far
Manny Ramirez might be the most frustrating case on this list. There were so many good things about him that still made fans want to laugh and shrug while saying the phrase "Manny being Manny".
His play was always incredible, as he was one of the premier sluggers of his era. But the number of big mistakes he made just couldn't be overlooked. First, he was suspended for 50 games for violating MLB's drug policy. That was violated again, which resulted in an additional 100-game suspension.
Those violations were well after the steroid scandals that were happening around him earlier in his career. One can only assume, though it has never been factually revealed, that he must have had a hand in those too.
2. Milton Bradley: Baseball’s Powder Keg
We talked about Albert Belle earlier on this list and mentioned how his temper flared to the extreme. Milton Bradley was a similar case to that on a different level.
First of all, he had all the bat-breaking and equipment-smashing that we have seen before throughout baseball history. Secondly, and more importantly, he actually had those issues become a problem at home.
Domestic violence allegations did not bode well for the perception of Bradley throughout the rest of his career, and his statistical output was maybe the only thing keeping him on the field, though not for very long.
1. Gary Sheffield: The Confrontational Slugger
This is a slugger who kind of combines a lot of the other entries on this list. He has a strong link to steroid use and brought a combative personality to the clubhouse. I'm not saying it went as far as Milton Bradley, or even Albert Belle, but let's just say that Sheffield wasn't the friendliest.
His long career saw him accumulate some of the magic thresholds that many Hall of Famers have hit. But his perception, along with his steroid link, will probably prevent him from getting in.
