At first glance, Ken Rosewall’s record seems simple: he won a Grand Slam singles title at 37. But the answer changes depending on whether you mean the modern Open Era or all of tennis history. In the Open Era, Rosewall is the oldest men’s singles champion and Serena Williams is the oldest women’s. Counting pre-Open Era Wimbledon champions, Arthur Gore and Charlotte Cooper won titles at older ages.
The oldest Grand Slam champions in singles
Here are the key records. The ages for the early champions come from an era with very different tournament formats, so they are useful historical comparisons, not like-for-like comparisons with today’s draws.
| Record | Player | Tournament | Age |
|---|---|---|---|
| Oldest men’s singles champion, all eras | Arthur Gore | Wimbledon, 1909 | 41 years, about 6 months |
| Oldest women’s singles champion, all eras | Charlotte Cooper | Wimbledon, 1908 | 37 years |
| Oldest men’s singles champion, Open Era | Ken Rosewall | Australian Open, 1972 | 37 years, 62 days |
| Oldest women’s singles champion, Open Era | Serena Williams | Australian Open, 2017 | 35 years, about 4 months |
Ken Rosewall: the Open Era men’s record
Ken Rosewall was 37 years and 62 days old when he won the 1972 Australian Open, beating fellow Australian Malcolm Anderson in the final. The tournament’s final was played in early January. Rosewall’s achievement stands out even more because he was not simply playing on the strength of past reputation: he was still good enough to win seven matches and take the title.
Rosewall had built his game around control and economy. His compact strokes, famously effective backhand and sharp sense of timing helped him redirect pace rather than rely on overpowering opponents. That kind of precision can age well: it does not depend as heavily on explosive movement as a game built around constant full-court recovery and big, high-risk hitting.
The Australian Open victory was part of a remarkable career across eras. Rosewall won major titles before the Open Era began in 1968 and continued winning after professionals were allowed to compete in the majors. He also claimed the 1970 US Open, aged 35, before his Australian triumph two years later. His 1972 win remains the Open Era benchmark for men’s singles age.
Serena Williams: the Open Era women’s record
Serena Williams set the women’s Open Era mark at the 2017 Australian Open, aged 35. She defeated her sister Venus 6–4, 6–4 in the final to win her 23rd major singles title, moving ahead of Steffi Graf’s 22 in the Open Era. Serena did not drop a set during the tournament.
Her performance was a reminder that experience is more than knowing what to do in a tight moment. Serena could still use her serve to take control of points, then follow with aggressive groundstrokes that forced opponents to defend. She later revealed that she had been pregnant during the tournament. That detail adds to the story, but the title itself came from the tennis she played over the fortnight.
Serena’s record is specifically an Open Era one. The oldest women’s singles champion across all eras was Britain’s Charlotte Cooper, who won Wimbledon in 1908 at 37. Cooper’s title came in a very different time for the sport, when equipment, training, travel and tournament structures bore little resemblance to the modern game.
Why Arthur Gore is older than Rosewall
Arthur Gore won Wimbledon in 1909 at about 41 and a half, making him the oldest men’s singles champion when pre-Open Era results are included. That puts him several years beyond Rosewall’s age at the 1972 Australian Open.
There is an important historical wrinkle: Wimbledon then used a “challenge round” system. The previous year’s champion could be entitled to meet the winner of the other matches in a final, rather than play through the same draw as every entrant. Gore’s 1909 title was earned under that format, not the modern seven-round route. His championship is a real part of tennis history, but comparing it directly with a present-day major requires that context.
Early major records also need a little care because the sport’s tournaments and definitions developed over time. The modern Open Era began in 1968, when professionals became eligible to compete alongside amateurs in major championships. That is why record lists often separate Open Era marks from all-time historical ones.
What makes a late-career major win possible?
There is no single formula for winning a major in your thirties. Rosewall and Williams had very different styles, but both could build points around strengths that held up under pressure. Rosewall’s control and anticipation helped him make opponents play one more ball. Williams’s serve and first-strike power gave her a way to shorten points and dictate their direction.
Experience can also make a difference over two demanding weeks. A veteran has usually seen more match situations and may be better at recognizing when to change tactics, conserve energy or take a calculated risk. That does not erase the physical challenge: recovery, movement and the schedule remain demanding. A late-career champion has to combine physical readiness with a game plan that uses their best weapons efficiently.
It is also worth separating singles from doubles. Grand Slam tournaments award titles in several events, and doubles champions can be older than singles champions. The records above answer the usual question about the oldest player to win a major singles title.

Final Thoughts
The clearest short answer depends on the era: Ken Rosewall is the oldest men’s singles champion of the Open Era, and Serena Williams is the oldest women’s. Look back across all tennis history, and Wimbledon champions Arthur Gore and Charlotte Cooper hold the older age records.
