3.A. League matches and matches in MSRA sanctioned singles tournaments shall be played according to the World Squash Singles Rules 2009 (eff. April 1, 2009) (the "Rules").

        
For leagues, the scoring to be used depends on the league as follows: 
 

1.  Open and Women’s league matches shall utilize standard, PAR-11 scoring as defined in Section 2 of the Rules, provided that in any individual league match the two players may by mutual agreement choose instead to play either of the alternative scoring systems specified in Appendix 7 of the Rules, being (i) "Server Only Scores - the previous standard scoring system" (HiHo 9), or (ii) "Point-a-Rally (PAR) to 15".

2.  Handicapped 50+ and Summer league matches shall utilize point a rally scoring to 15, specified in Appendix 7 as "Point-a-Rally (PAR) to 15", modified:
(i) to account for handicaps as defined in Section 4 of these rules, and
(ii) to provide that the player who scores 15 points first wins the game, regardless of any tie at 14-all.
