Which MLB fanbases are the biggest team players?

Be honest… Would you give up your last nacho for a rival baseball fan in need? Still back your team when they’re down and out? Skip the trash talk about other teams? PromoGuy set out to find which MLB fanbase keeps it cool and shows true team spirit, even in the heat of the moment. We surveyed 2,000 fans to find out who’s really knocking it out of the park as the ultimate team player.

This is what we found:

Miami Marlins fans top the charts as the biggest team players in the MLB, with a score of 77%.
Hoping to snag a nacho from a rival fan? Seattle Mariners fans are the least likely to share, while Miami Marlins fans are the quickest to pass the plate.
Minnesota Twins fans lead the way when it comes to keeping things classy and avoiding trash talk about rival teams.
New York Mets and Washington Nationals supporters stand out for cheering their team on, even when the scoreboard isn’t in their favor.
Marlins fans lead the league in looking out for others.

Measuring true team players among MLB fans

“Teamwork makes the dream work”, right? Sure, it’s a classic for a reason. But in the heat of the moment, that team spirit can fly out of the stadium faster than a home run ball. That’s why it’s worth celebrating the fans who do keep their cool and play like true team players.

In the middle of the MLB season, PromoGuy pitched a series of statements to 2,000 baseball fans across the country. They rated how much each one applied to them, on a scale from 1 (not at all) to 5 (very much so):

I cheer for my team even when they’re losing.
I stay until the end of the game, no matter the score.
I’ve sometimes helped fellow fans at games (e.g. directions, medical help, finding their seat).
I avoid trash talking other teams or their fans.
I’d offer my last nacho to a rival fan in need.

Top 3 MLB fanbases with the biggest team player spirit

Miami Marlins fans take the crown as the biggest team players, scoring an impressive 77% on average across all the statements. On the flip side, their Florida rivals, the Tampa Bay Rays fans, come in last, with the lowest score of 63%—a mark they share with Philadelphia Phillies supporters.

Washington Nationals come in second place with a solid 75% team player score. They top the charts when it comes to sticking it out through the whole game, no matter the score. Plus, they tie with the New York Mets for cheering for their team, even when they’re behind.

Sharing third place are the Arizona Diamondbacks and LA Angels fans, each with a team player score of 74%.

Iowa and Mississippi baseball fans are the ultimate team players

When it comes to team player scores by state, Iowa and Mississippi lead the pack. Neither has their own Major League Baseball team, but both still top the charts with a solid 74% team player score. Iowa shines when it comes to helping out at the ballpark—whether it’s offering medical assistance or helping fans find their seats. Mississippi, on the other hand, shares the top spot with Louisiana and Kentucky for being the most likely to share their last nacho with a rival fan in need.

Nevada fans lead the league… in keeping their nachos

In Utah, team spirit isn’t exactly the name of the game. Fans there have the lowest average team player score in the country: just 48%. Nevada doesn’t do much better, scoring 52%, and ranks last when it comes to sharing a nacho with a rival fan. South Dakota also trails behind, with the third-lowest overall score at 60%. And when it comes to cheering for their team even when they’re behind, South Dakota lands the lowest score of all states.

Methodology

To find out which MLB fans are the biggest team players, PromoGuy conducted an online survey through the research platform Prolific on June 3, 2025. The sample consisted of 2,000 baseball fans living in the United States. They were asked which state they live in, their favorite MLB team, and then presented with five statements that they rated on a scale from 1 (not at all) to 5 (very much so), indicating how much each statement applied to them. Of all respondents, 55% were male, 44% female, and 1% non-binary. The average age was 42.1 years. The following states were excluded due to insufficient data: Alaska, Hawaii, Maine, Montana, New Mexico, North Dakota, Vermont, West Virginia and Wyoming.
