Overview
- The Jones twins worked both games of a doubleheader at Camden Yards on Wednesday, Sept. 23, 2026, making them the first identical twins to umpire together in a major league game.
- Baltimore won each game 4-2 and the brothers split base assignments by swapping first and second base between the opener and the nightcap.
- Both began umpiring as teenagers in Summerville, South Carolina, entered the minors in 2014, and made separate MLB debuts—Austin in 2024 and Tyler in 2025—before spending 2026 primarily as Triple‑A call-up umpires.
- MLB uses Triple‑A officials to fill short-term gaps, and doubleheaders use a five-umpire alignment instead of four, which created the extra roster spot that allowed Austin to join Tyler on the crew.
- Independent tracking by Ump Scorecards rates both brothers in the mid-94% range for accuracy and consistency, and their family presence at the game highlighted the personal significance of the milestone.
