All amateur divisions will be played according to official USA Racquetball rules, including the mandatory use of protective lensed eyewear tested to ASTM F803 or CSA impact standards. Pro divisions will use IRT/WPRO/CPRT rules. For all age divisions, players must meet the proper age requirement as of the first day of the tournament (October 21st). All divisions (pro and amateur) will use the ProPenn HD (purple) ball, the official ball of the IRT and US OPEN. Consolation will not be offered due to court time restrictions. Every match played in all divisions at the US OPEN will be entered in the USAR’s new state of the art ranking system.
