AFL Instant Replay Update: Umpires Perfect in Game 1

AFL instant replay was used to confirm umpire calls four times during Tuesday's testing debut, including three safe/out calls at first base and one trap in shallow left field. Presiding over the system on the field was veteran minor league umpire and AAA call-up Hal "Tripp" Gibson of the Pacific Coast League, who served as home plate umpire and communicated with MLB umpires supervised by Ed Montague and located off the field.

Managers of both Arizona Fall League clubs involved in Tuesday's contest were encouraged to invoke instant replay challenges in an effort to facilitate the technology's testing phase.

Replay #1: Out (Upheld) / With none out and none on in the top of the 2nd inning of the Solar Sox-Rafters game, Angels prospect CJ Cron hit a ground ball to Cardinals minor leaguer Jacob Wilson, who threw to first base as Cron arrived.
