Overview

• The Diamondbacks revoked Dave McCaskill’s Advantage Member account and barred him for the rest of 2025 for “multiple offenses” at Chase Field.
• On June 30, McCaskill reached over the left-field wall to catch a Christian Koss fly ball, triggering an interference call that was overturned on replay and ruled a ground-rule double.
• Internet researchers uncovered footage of at least five additional incidents since 2022 in which McCaskill’s actions prompted umpire reviews.
• In media interviews, the retired veteran defended his intent as benign while acknowledging two to three ejections and roughly nine or ten reviewable plays over the years.
• The team said McCaskill may return in 2026 only if he meets specified terms and fully abides by the Fan Code of Conduct.
