5 oldest French Open men's singles champions in the Open Era

#2 Ken Rosewall

Ken Rosewall

The second Australian in this list is Ken Rosewall. Although diminutive in stature and lacking a strong serve, Rosewall made up for his weaknesses by being extremely agile and developing one of the best backhand slices that the game has ever seen.

Rosewall is the only player to have won a Grand Slam title in three different decades (the 1950s, 1960s and 1970s).

He won his very first French Open title in 1953, at the age of just 19. His second and last French Open title came 15 years later (an all-time French Open record for number of years between first and last victory), in 1968.

Rosewall was seeded No. 2 that year, and in the final he faced off against the Number 1 seed and fellow compatriot Rod Laver.

Rosewall would beat his good friend on this occasion. He was 33 years, 220 days old at the time of his victory.
