2009 New Tournament Ranking System

Rogers Rankings | The last time the tennis ranking system in BC changed was at the beginning of 2008. The ranking system prior to 2008 was around for a long time and was based solely on the accumulation of points during the year. Points were earned according to how far you progressed in the draw. This model rewarded quantity of events played over quality of results achived. This obviously favoured anyone who kept playing tournaments after tournaments. The drawback was someone can be ranked in the top 10 of their category without being capable of beating the other top 10 players. So on January 1 of 2008, the ranking system was changed to reflect the relative merit of all players in the system. After getting feedback from players and tournament directors, the ranking was more closely tied to the player's usual tournament performance and weighted for participation. The rating was then based on the player's average points per tournament multiplied by a participation factor. This was not a major change, but it did strengthen the accuracy of the rankings to a certain degree. By the end of 2008, it appeared that this change was only an interim measure because a completely different ranking system was already underway and would be introduced on January 1 of 2009. Every match data in 2008 were input in the computer so that an initial ranking list can be achieved by January 1 of this year. So what is it?


This new and enhanced ranking system known as the Rogers Rankings is based on the proven Chess Elo ranking system. The Elo system was invented by Arpad Elo, a master-level chess player, and was implemented in 1960 by the United States Chess Federation as an improved chess rating system. Today it is also used in many other games. The primary goal of Elo ratings is to accurately predict the game results between the competitors. This new Rogers Rankings system will award points to players based on quality of wins, which are the head-to-head results, rather than rounds won in a tournament, as in the previous tennis ranking systems. Thus in a head-to-head match up, the stronger (or higher ranked) player is expected to win, while the weaker (or lower ranked) player is expected to lose. And over time, the system generates accurate rankings due to its ability to evaluate the calibre of the competing players. In this case, every sanctioned match that a player plays, be it at the international, national, provincial or at the local level, points will be used to compute one common national ranking, irrespective of age, and can be sub-filtered into provincial rankings, over 35 rankings, under 18 ranking and so on. Sanctioned league and club matches may one day be included in this ranking system.


Rogers Rankings have been fully tested for a year, and the data that have been fed into the common database, the BASELINE management system, in 2008 will provide the initial ranking to determined the point values for matches since the beginning of this year. At present, only the juniors (U12 to U18) and the adults (3.0 to 5.5 and open) singles rankings will be Elo ranked. Senior head-to-head ranking may be added in 2010, and doubles may also be ranked this way in future. In order for a new player to enter the system, the player must accumulate at least one win and two losses against players who are already ranked over the course of 12 months. This will give the player a temporary ranking for which an initial ranking can be obtain. Results against players who do not have an initial ranking will be counted later once the unranked player becomes ranked. Each time the BASELINE ranking system is updated, it will automatically checks for new players inclusion into the rankings and adjust all the points against these new players retroactively. So for some players, new ranking points will be added or subtracted even when no match has been played during this time.


To further enhance the head-to-head points value, a star value system will highlight the importance of certain tournaments or events. The higher the star value, the higher the point gains or losses. National tournaments have a 5 star value, while at provincial level, a 4 to 1 star value is awarded. At the local level, a 2 or 1 star value is assigned.


The table below shows the various point values under the star value system. An example, male player A has 3800 points and male player B has 3500 points. The points spread between these two players is 300. Finding this 300 point difference is in the row 300–399 which gives a +/– 4 and a +/– 78 under the 5-star column. If the higher ranked player A wins, under the "higher" column, he will receive only 4 points to add to his 3800 ranking points, and the lower ranked player B will lose 4 points from his 3500 ranking points. So the new ranking points for A will be 3804 (3800 + 4) and player B will get 3496 (3500 – 4). If the lower ranked player B wins the match, he will get 78 points added to his previous total of 3500, while the higher ranked player A will lose 78 point from his existing ranking. So player A will be ranked with 3722 points (3800 – 78), and player B will improve his ranking point to 3578 (3500 + 78).




Default match will automatically result in a lost of 20 points, and a gain of 20 points for the opponent. A third default match within a 12 month period will mean a suspension from sanctioned tournaments for three months and a lost of 50 ranking points after the suspension period has ended. Player retiring from a match during play will lose points as in a regular match.


How good will this new national ranking system gets to be, time will tell. Tennis Canada has claimed Tennis Quebec has been using this framework for more than 20 years with exceptional accuracy. This ranking format is also consistent with the national ranking systems of Spain, France and Germany. Anyone can view the provincial rankings and players' match history through the respective provincial association's website. On the Tennis BC website, information on the Rogers Rankings has not been updated. Tennis Canada updates the national rankings on their website every Monday.

Final Day of Competition



Day 4  |  Coquitlam Junior Spring Challenger  •  After a nice spell of hot sunny days, the morning cool air and cloudy sky gave an indication that the wet weather was on its way as forecasted. The morning started off with several semi-finals matches. In the Boys' U14 event, Tian Xu Wen, who trounced the No. 1 seed Brendan Guay yesterday, moved into the finals scheduled for the afternoon with an easy 6-0, 6-4 victory over Gobind Pangli of Abbotsford. He will pit against Ryan Emanuele for the title. Emanuele set up another personal best when he defeated the No. 2 seed Jake Perkins 2-6, 6-3, 6-1. This was his third three-sets match in the last four matches he played. So it was down to these two unseeded players who had a great run through their own half of the draw. The finals was moved indoor because of the rain. After a hard fought match from both players, Wen leaped and cried out in exuberant when he won the final point in the 7-6, 6-4 scoreline to claim the title. In a rain interrupted finals, Daniel Dziamaga, seeded No. 3 fought off a second set challenge from Thomas Stokes to finish the match and take the Boys' U16 singles title. He defeated Stokes 6-2, 7-5. The Boys U18 finals had managed to complete before the sky opened up. This finals was an all CTC affair. Ilya Tihanenoks extended his head-to-head lead over his clubmate Tyron Wheatley with an easy score of 6-2, 6-0. In one other boys' finals, which was postponed to a later date, top seed Brendan Artley playing in his first finals beat Vancouver's Ben Kirsh 6-3, 7-5 in the Boys U12 event. CTC's Ryan Sandrin was stopped in the semi-finals of the Boys' U16 consolation draw after Steven Shim edged him out in a close three sets match. After both boys were tied at one set a piece, it all came down to the super-tiebreaker third set. The final score was 6-3, 4-6, 10-7. Other results: Anand Dhatt defeated Owen Stimpson 6-4, 7-6 to win the Boys' U10 singles; Jessica Gong beat Alexandra Meshcherekova 4-6, 7-5, 10-3 to claim the Girls' U10 singles.
