The Arizona Diamondbacks have taken decisive action against a season ticket holder, banning him from Chase Field for the remainder of the 2025 season due to repeated offenses, including interference during a recent game against the San Francisco Giants. With the D-backs leading 3-2 in the eighth inning, fan interference occurred as Christian Koss hit a long fly ball, which was caught by the fan, leading to a controversial overturn of the out call. The team confirmed the ban following multiple inquiries about the incident.

Dave McCaskill, the ejected fan, acknowledged prior ejections and stated he has been reviewed several times over the years. The Diamondbacks emphasized their commitment to fan conduct, terminating McCaskill's Advantage Member account while allowing the possibility of reinstatement in 2026 under specific terms, highlighting the importance of adhering to their Fan Code of Conduct.
