Making the Top 100: ITF Top 10 junior transition to Top 100 ATP tour (1996 – 2005)

Almost 60% of players who achieve a top 10 ITF junior ranking go on to achieve a career high ATP ranking in the top 100. Research has now revealed how long this transition takes and at what age it usually occurs.

Achieving a Top 100 ATP rank is a significant achievement in men’s professional tennis. Much discussion surrounds the path a player and time a player should take in achieving this goal. There have been a number of studies that have profiled average age of top-ranked male and female tennis players (Tennis Canada, Treleven & Miley). This study investigated transition from a Top 10 ITF Junior rank to Top 100 ATP Tour rank over a ten-year period between 1996 and 2005. It provides an insight into the development variables of ITF junior win: loss ratios, number of junior and ITF Pro-Circuit events played between 14-18 years of age and ranking in the years prior to entering the Top 100. The intended use of this study was to establish a range of statistical benchmarks coaches and Federations can use for players aspiring at a professional career on the ATP Tour.

• The study’s data was obtained from the ITF and ATP Tour websites: www.

• Data was collated on players meeting the criteria of:

Top 10 ITF Junior year-end rank between 1996 – 2005. (85 players*)
