On 1 January 2004, the ITF introduced the Combined Junior Ranking. The Combined Junior Ranking replaced the Junior Singles and Junior Doubles Rankings and is the sole junior ranking published by the ITF.
The introduction of the Combined Junior Ranking aims to encourage the doubles game at junior level and subsequently at professional level.
Experiments carried out by the ITF show that in general the best singles players remain at the top of the Combined Ranking. However, the importance of the doubles points becomes evident when two players have the same or similar singles points totals, in this case the player who has achieved better doubles results is ranked higher. Therefore a player who does not participate in any doubles events will be at an automatic disadvantage.
How it works?
A player's ranking is calculated using the best six singles results plus one quarter (25%) of the best six doubles results. For example:
Best 6 Singles results = 950
Best 6 Doubles results = 880
One quarter of 880 = 220
950 + 220 = 1170 = Combined Ranking points total
Points continue to be counted on a 52 week rollover system.
