Final Top-100 Age Matrix

Final installment in the 'Age Matrix' from 1973-2011 (except 1982).

The age has been rounded up to the year-end hence is a bit off from the calendar perspective.

1. Youngest Open Era entrants - Agassi (1986) and Chang (1988) @16 years old.

2. Oldest Open Era in Top 100 - 'Muscles' Rosewall (1978) @ 44 years old followed by Connors (1992) at 40 followed by Santoro (2009) @ 37.

3. The number after the year in the headings is the number of age entries for that year. For example 1978 (20) means for year 1978, there are 20 distinct entries, one for each 'age' number.

4. From 2004 onwards, below-21 players drop into single digits.

5. The last 'total' line is just for validation. (The 98s and 99s are known issues with ATP data).
