North American Doubles

Ranking System & Seeding Criteria
Revision- July 16th, 2009

As North American doubles tournaments have proliferated in both number and participants, there has been an increased need for a ranking system to both recognize accomplishment and importantly to help tournament directors seed their events more accurately. Accordingly, a formulaic ranking system has been created to include both Canadian and United States events. The system has the following characteristics:

  • A player will obtain a ranking if he/she plays in a sanction event. Rankings take into account the best four (4) results for Men and the best three (3) results for Women over the past two (2) years from all approved accredited (sanctioned) play. For OPEN rankings only, a player requires a minimum of 3 OPEN results. Open results only will be used for ranking purposes and the player’s points from age group events will not be carried down into the Open point accumulation.
  • Rankings are based on total point accumulation from a player’s best results over the course of a two-season revolving cycle. Points are allocated by tournament results:

Champion = 60
Finalist = 45
Semi-finalist = 30
Quarter finalist = 15
Round of 16 = 5
Round of 32= 3
Entry in draw (1st round loser) =1
¾ Playoff = Bonus of 5
5/6 Playoff- Bonus of 2
Consolation Winner=Bonus of 5

  • For ALL AGE CATEGORIES – Points for the current year are valued at 100% and at 75% for the previous year. The total accumulated points are divided by 4 for Men’s and 3 for Women to determine a player’s current ranking point total. A player may be ranked in younger age category(s) other than the category of the player’s current age provided the player has either a minimum of one result in a US or Canadian National Doubles Championship in the younger age group (except for the purposes of an Open ranking) within the two year period OR has played a minimum of three events in that younger age group over the past two years.
  • For WOMEN’S OPEN – Points for the current year are valued at 100% and at 75% for the previous year. The total points accumulated may only be obtained from a Women’s Open event. The total points accumulated are divided by 3. OPEN results will be included in a player’s age ranking if the result constitutes one the player’s best three results required for averaging purposes.
  • Each draw of each age category will be weighted by both the age factor and the depth of draw.
  • AGE WEIGHTING – MEN commences at a value of 1 for OPEN, .8 for 40 years, and .64 for 45 years etc. WOMEN commence at a value of 1.25, .8 for 40 years. All older age categories will be weighted at 80% of the value of the previous division. For example, points earned in the 55’s are worth 80% of the same points earned in the 50’s. This process enables players moving up a division in the two-year period to carry results forward into the new division.
  • STRENGTH OF DRAW – Weighting. Each age division is assigned a “strength of draw” factor based on the rankings of the players in the draw prior to the tournament being played. That factor is multiplied by the points earned in the division. All non national accredited draws* commence with a .5 weighting and are subject to the following increases by players ranked in the top 21 entered up to a maximum of 2.5. In the case of an Open the draw a minimum of one player must be ranked in the top 25 otherwise it shall be weighed at .3 (* All Canadian & US Nationals commence with a .75 weighting). Furthermore, in the event of OPEN men’s draw with ranked ISDA players the maximum allowed weighting is 3.
#1 & 2= player= .2 each  .40
#3 & 4=players=. 175 each  .35
#5 & 6=players= .150 each  .30
#7-11=players= .1  .50
#12-16 players= .05  .25
#17-21 player= .04  .20
Total 2.00

Therefore in a draw where 21 of the top ranked players on the North American Ranking system all played, the draw would be weighted as a 2.5.ISDA players with no established NA Ranking will use the most current ISDA Ranking as of the month of the event, with the following weighting:

#1-6= .25 each  1.5
#7-12= .20 each  1.0
Total  2.5
  • The Ranking Committee retains a degree of discretion to account for players/teams with an established history but insufficient data. From .20 to .35 may be added in the case of a wild card player who does not or has not played sufficient events to warrant the appropriate ranking. The maximum of 2.5 strength of draw weighting factor per event (except OPEN with ISDA players which is 3.0) may not be exceeded by the inclusion of wild card players.


1) Seeding for all tournaments will be determined by combining the total points of the 2 players on a team from the latest North American Rankings which is the result of the average of individual best 4 results (3 events for the Women’s) over a 2 year tournament cycle. (Note mixed rankings are not included in Men/Women ranking totals and visa versa) Ranking points only will determine the seeding process except for Dark Horse teams.

2) For players who are ranked in the top 20 of the then-current ISDA Rankings, they shall be seeded based upon the following formula: The #1 ranked ISDA player shall have 20% more points than the current #1 ranked NA player with a corresponding 2% reduction in points for each player in the top 20 of the ISDA (for example, the # 10 ISDA player would have the same number of points as the then-current #1 ranked NA player and the 20th ranked ISDA player would have 20% less points then the current #1 ranked NA player). For those individuals that have both ISDA points and NA points, the seeding committee shall take the higher of their NA points or the points they would be entitled to under the top-20 ISDA formula aforesaid.

3) “DARK HORSE TEAMS” Those players/teams with an established doubles history but insufficient current data will normally be placed to meet in the 3rd or 4th quadrant of the draw. At the discretion of the seeding committee having jurisdiction over the tournament, dark horses may be placed and or seeded but not seeded higher than 3rd.4) Past champions have no precedence over a team with more ranking points.


1) For all National events a maximum of 25% of the draw must be seeded and no more than 50% of any draw may be seeded and or placed.(In the event of a fraction, round up to the higher number)

2) The format for seeded players must be placed as follows:1 plays 4
2 plays 3
5 plays 4
6 plays 3
7 plays 2
8 plays 1

3) All draws must have player’s full name and home city on the draw. Emphasis must be given to avoid players form same city or club meeting in the 1st round and also be given to avoid teams playing the same team they have played in a recent tournaments in 1st rounds when ever possible.

4) All draws of 6 teams or less should be in a round robin format.

5) Any draw with 6 teams or more shall constitute an official draw regardless of the number of teams in the lower age category.

6) All Canadian National draws will be prepared by Squash Canada in conjunction with the Squash Canada Doubles Seeding Committee.

7) For U.S. events, the individual tournaments may, in circumstances which the tournament’s seeding committee deems just and proper to insure a fair draw, deviate from the within “Guidelines” at their discretion.
