As video replay technology has become more prevalent in major professional sports leagues, officials and players have developed a unique set of hand signals and gestures to communicate during reviews. From the ubiquitous NBA finger twirl to the new MLB head pat for the Automated Ball-Strike Challenge System, these non-verbal cues have become an integral part of the game experience for fans and participants alike.

Why it matters

The rise of video replay has transformed how officials and coaches interact during games, creating the need for a shared gestural language to efficiently navigate the review process. These signals not only help streamline decision-making, but also add a layer of drama and fan engagement to the viewing experience as spectators learn to recognize and interpret the various hand motions.

The details

In the NBA, the finger twirl is a common sight as players and coaches signal for a video review, while in the NFL, the red challenge flag thrown by coaches has become an iconic moment. International sports like soccer and cricket have their own versions, such as the rectangular box drawn in the air for VAR reviews and the 'T' sign for the Decision Review System. MLB's newest addition is the head pat, used to initiate the Automated Ball-Strike Challenge System. These signals have become so ingrained in the sports lexicon that fans have started to adopt them as well, patting their heads when they believe a call has been missed.

  • The Automated Ball-Strike Challenge System was officially introduced in MLB games in 2026.
  • The ABS system was used on an experimental basis during MLB spring training in 2025, but was not allowed during the regular season until 2026.
