I worked the ASA Mens FP 40 and Over this past weekend. Only 5 teams, 6 umpires.
All games were three umpire, one on, one off until one of the umpires tweaked a knee and could not continue.
All games were at the same field, which was nice, because our UIC could watch every pitch of every game and provide a complete evaluation.
One of the best National Tournament experiences that I have had.
