Diamondbacks Ban Fan for Repeated Interference

The Arizona Diamondbacks have banned season ticket holder Dave McCaskill from Chase Field for the rest of the 2025 MLB season after he interfered with a live ball by reaching over the outfield wall during a game against the San Francisco Giants. The incident, which happened Monday night, led to McCaskill's ejection from the stadium, and the play was initially ruled an out before being overturned to a double following review. The Diamondbacks ultimately won the game 4-2. McCaskill's ban comes after at least four interference incidents in the past four years, with the team citing multiple offenses and increased public scrutiny as reasons for making an exception to their usual policy of not commenting on individual cases. McCaskill may return in 2026 if he complies with the team's Fan Code of Conduct. The case has reignited debate about fan behavior and enforcement of stadium rules amid other recent MLB fan controversies.
