Major National Regulation Changes for 2010
1. A player with a valid NTRP Computer (C) rating, or Benchmark (B) rating, or granted Automatic Appeal rating of a Computer (C) rating is not subject to a NTRP grievance. Any other player is subject to a NTRP grievance.
2. Each player shall have reached eighteen (18) years of age prior to, or during, the calendar year in which such player plays his/her first local league match.
3. Adult, Senior and Mixed teams that qualify to advance to National Championships, but do not participate, will follow the Move-up/Split-up Regulations.
4. Players that are NTRP disqualified while participating in another division after qualifying for Adult, Senior, Mixed, or Super Senior National Championships will not be allowed to advance to the National Championship unless participating at the higher level.
MAJOR SECTION REGULATION CHANGES FOR 2009
1. In the Tri-Level division, the highest NTRP level offered will play in the #1 doubles position, second highest will play #2 doubles and lowest level offered will play in the #3 position. A player may play one level (.5) higher than their NTRP rating as long as one member of the doubles team is at level. For example: On a 3.5/4.0/4.5 team, a 3.5 player can play on the #2 doubles line as long as he/she teams up with a 4.0 player, otherwise, that line will be disqualified and entered as a default.
2. 50% of the players on a roster must be at level for the Adult and Senior divisions and the SCTA Doubles league.
3. The “50% at level” regulation will be suspended for one year for any team that participated at the Adult and Senior national championships the previous year and chooses to move up one level.
4. If players register on more than one team at the same level, in the same area, in the same division, they will be disqualified from the team(s) they last registered on and any matches played will be disqualified. If no matches were played, the player can decide which team to be deleted from. Exception: In the Trilevel division, a player can play at the same NTRP level on two different Trilevel teams. For example: A 3.5 player can play on both a 3.0/3.5/4.0 and 3.5/4.0/4.5 team.
5. Postponements/Reschedules for any reason other than unplayable conditions or at the request of a captain whose team (minimum of 4 players) advances to a league championship of another USTA/SCTA league division requires the approval of the ALC.
6. ALC’s have authority in specifying “unplayable conditions” in their local area.
7. All verbage regarding “Self-Rate Grievance” has been changed to “NTRP Grievance”.
TRI-LEVEL LEAGUES
A "team" shall consist of doubles teams of three NTRP levels. For example, a team may have doubles teams at 2.5, 3.0 & 3.5 or 3.0, 3.5 & 4.0 or 3.5, 4.0 & 4.5. The local league shall determine which approved levels will be available for Tri-Level teams in local league competition. Teams will advance to either Area Playoffs and/or Section Championship. The Sectional winners of the 3.5/4.0/4.5 level will have the opportunity to represent So Cal in the BNP Paribas Open Tri-Level Invitational Championship in March of 2010 at the Indian Wells Tennis Garden. This can be a great opportunity for friends to play on the same team that are at different NTRP levels.
