If you thought baseball drama stayed on the field, think again. One fan just made headlines in a way you really don’t want to if you're a regular at the ballpark.
Yep, we’re talking about Dave McCaskill, a self-proclaimed Diamondbacks superfan who’s now banned from Chase Field for the rest of the 2025 season. Why? A little too much enthusiasm—and one big reach over the fence—during a critical moment in Monday night’s game against the San Francisco Giants.
But this wasn’t your average case of fan overstepping. Oh no, this thing blew up. Media interviews, social posts, radio appearances—the whole nine yards. Let’s dive into how this all went down, what McCaskill had to say, and why the Diamondbacks decided enough was enough.
📌 Monday Night Mayhem: It All Starts with a Reach
During a crucial moment late in the game, Christian Koss of the Giants launched a deep fly ball that looked like it might tie the game. Arizona outfielder Tim Tawa tracked it to the warning track, but just as he got there, a fan reached over and snagged the ball barehanded. That fan? You guessed it—McCaskill.
Initially, the umpires ruled the play as fan interference and called Koss out. But after a review, they switched the call to a ground-rule double, noting McCaskill didn’t actually touch Tawa during the catch. The damage to the Giants' scoring opportunity, though, was done.
🎥 Social Media Detectives Go to Work
It didn’t take long for the online baseball community to start digging. Fans on social media identified at least four other close calls involving McCaskill, with him getting way too close to live balls in similar spots at Chase Field—some dating back to 2022 and, yes, including another Giants game.
Turns out this wasn’t McCaskill’s first rodeo when it came to fan interference controversies.
🎙️ The Media Tour Begins
Instead of laying low after the incident, McCaskill embraced the spotlight. He posted a video of the catch on Instagram, seemingly proud of the play, and hit the airwaves to tell his side of the story. He joined Arizona Sports 98.7 FM and later hopped on a call with KNBR in San Francisco, sharing some wild admissions.
“I’ve been ejected from three games,” he said, laughing. Though he clarified one ejection was more of a “hey, please move seats” situation. He also admitted that several balls he’s caught have gone to review 9 or 10 times.
🤝 Stadium Security, Laughs, and Some Awkward Moments
McCaskill said Monday night’s incident was met with a mixed bag of reactions from stadium staff.
“When the security guards came down, there were like eight of them and some sheriffs,” he said during his radio interview. “Half were laughing and patting me on the back. One of them, though, definitely wasn’t happy.”
That kind of notoriety doesn’t come easy—or cheap, as McCaskill soon found out.
❌ The Ban Hammer Drops
Just a few hours after his first interviews, the plot thickened. McCaskill was scheduled to join KNBR again around 3:15 p.m. Tuesday, but backed out last minute. Not long after that, Matt Nahigian, the program director of 95.7 The Game, reported that McCaskill’s tickets had been revoked for Tuesday night’s game.
McCaskill returned to KNBR around 3:30 p.m. to confirm the news himself. And then, just after 4 p.m., the Diamondbacks dropped the hammer in an official statement to SFGATE.
Here’s the core of that statement from Arizona’s front office:
"While our policy is to not publicly disclose information about our season ticket holders, the Arizona Diamondbacks are making this statement due to public speculations and multiple media inquiries regarding the fan interference incident during last night's game. This particular fan has been involved in multiple offenses at Chase Field. Consequently, we have terminated his Advantage Member account and he is prohibited from returning to Chase Field for the remainder of 2025."
They added that McCaskill may return in 2026—if he follows the Fan Code of Conduct.
🧢 A Superfan With a Side of Zack Hample Obsession?
In one of the more surprising reveals, McCaskill said he’s a big follower of Zack Hample, the famously polarizing baseball collector known for snagging thousands of foul balls and home runs across MLB stadiums.
McCaskill clearly sees himself as a kind of local legend at Chase Field. He even suggested that stadium staff know him by name and generally enjoy his antics—until now, of course.
⚾ The Bigger Picture: When Passion Crosses the Line
There’s a fine line between being an enthusiastic fan and becoming a distraction—or even a liability. McCaskill may have felt like he was just doing what fans like Hample are known for, but the context here matters: game-changing play, late innings, playoff-race stakes, and, most importantly, interference.
Even though he didn’t physically touch the player, reaching over the fence is enough to throw off a play, or at least cause chaos on the field. That’s exactly why MLB has rules—and why teams like the D-backs have to enforce them, even against their own diehard fans.
📅 What’s Next?
The Diamondbacks and Giants are still battling it out in their four-game series at Chase Field, with Game 2 kicking off Tuesday night at 6:40 p.m. But one familiar face definitely won’t be in the stands.
Whether McCaskill lays low until 2026 or tries to find another way into the stadium (please don’t), this incident is likely to remain one of the wildest off-field stories of the D-backs’ 2025 season.
