You’d think with all the modern science, ice baths, and personalized nutrition, someone would have knocked Ken Rosewall off his perch by now. It’s 2026, and we are still talking about a record set in 1972. Think about that.
When Ken Rosewall stepped onto the court for the 1972 Australian Open final, he wasn’t just playing against Mal Anderson; he was basically fighting time itself. He was 37 years, one month, and 24 days old. In an era where players often hung up their rackets by 30, "Muscles"—as they ironically called the slight, 5'5" Aussie—was busy winning his eighth major.
Honestly, the story of the oldest tennis grand slam winner isn't just a trivia point. It’s a testament to how the game has changed—and how some things, like a perfect backhand, just don't age.
The Day the Record Was Set
Melbourne in January is no joke. We're talking 100-plus degree heat. On the day of the final, Rosewall’s car actually broke down on the way to the stadium. Imagine the greatest player of his generation walking toward the Kooyong Lawn Tennis Club, rackets in hand, sweating before the match even started.
He didn't just win; he dominated. He beat Anderson in straight sets. What’s wild is that Rosewall won his first Australian title in 1953. Winning again 19 years later? That’s a gap no one has come close to touching.

Djokovic, Federer, and the "Almost" Club
For a while there, everyone thought Novak Djokovic would be the one to finally erase Rosewall from the top of this specific list. Djokovic is 38 now. He’s still a machine, obviously. He reached the semi-finals of all four Slams in 2025, which is insane for his age. But winning the whole thing? That final step has proven tough lately with Alcaraz and Sinner playing like they're from another planet.
Djokovic did grab the US Open in 2023 at 36 years and 3 months. He’s currently the third-oldest man to win a major in the Open Era.
Then you have Roger Federer. The Swiss Maestro won the 2018 Australian Open at 36 years and 5 months. At the time, it felt like he might play forever. But even Federer couldn’t quite reach that 37-and-change mark that Rosewall established back when wooden rackets were still the standard.
The Men's Leaderboard (Open Era Singles)
- Ken Rosewall: 37 years, 62 days (1972 Australian Open)
- Roger Federer: 36 years, 173 days (2018 Australian Open)
- Novak Djokovic: 36 years, 111 days (2023 US Open)
- Rafael Nadal: 35 years, 11 months (2022 French Open)
What About the Women's Side?
If we are talking strictly singles, Serena Williams is the queen of longevity. She won the 2017 Australian Open while pregnant—which is a whole different level of legendary—at the age of 35 years and 124 days.

People often forget how close Martina Navratilova came to rewriting the singles record, too. She was 37 when she made the Wimbledon final in 1994, losing a tight three-setter to Conchita Martínez. If she’d won that, she would have technically been the oldest tennis grand slam winner in singles, male or female.
The Absolute Oldest: Martina’s 50-Year Milestone
If we stop looking at singles and look at any Grand Slam trophy, the conversation shifts entirely to Martina Navratilova.
In 2006, just weeks before her 50th birthday, Martina teamed up with Bob Bryan to win the US Open Mixed Doubles title. She was 49 years and 326 days old. Read that again. Nearly 50.
Most people her age are booking knee replacements, and she was out there poaching volleys at Arthur Ashe Stadium. It’s probably the most untouchable record in the sport. She finished her career with 59 major titles across singles and doubles.

Why These Records Are Getting Harder to Break
You'd assume better medicine means older winners, right? Sorta. While players stay fit longer, the physicality of the game has skyrocketed.
In Rosewall's day, points were shorter. There was more variety, more slice, more net-rushing. Today, every point is a baseline war. Facing a 22-year-old Jannik Sinner who hits the ball like he’s trying to break the sound barrier is exhausting for a 38-year-old body. The recovery time just isn't the same.
Novak Djokovic is still the best bet to break Rosewall's singles record. He’s incredibly disciplined. He treats his body like a temple, or a high-end Ferrari, or whatever metaphor you want to use. If he wins the Australian Open or Wimbledon this year, Rosewall finally drops to number two.
Practical Takeaways for Fans and Players
Looking at these "old" champions actually teaches us a lot about how to play tennis for life:
- Efficiency over Power: Rosewall didn't have a massive serve. He had "Muscles" in his legs and a backhand that never missed.
- Adaptability: Navratilova moved from a serve-and-volley singles specialist to the world's best doubles partner as she aged.
- Mental Grit: Winning a Slam at 36 or 37 requires a level of psychological endurance that younger players often lack.
If you’re tracking the 2026 season, keep a close eye on the draw. Every time Djokovic or a veteran like Rafael Nadal (if the body holds up) enters a tournament, they aren't just playing for a trophy. They are chasing a 54-year-old ghost named Ken Rosewall.
To stay ahead of these records, you should follow the live ATP and WTA rankings closely, as "age records" are often broken in the doubles circuits long before the headlines catch up. Check the official Grand Slam archives if you want to see the exact day-and-month breakdowns for legends like Bill Tilden or Molla Mallory from the pre-Open Era, as those "all-time" stats sometimes vary from the modern professional records we usually cite.
