Since the start of the Open Era, tennis has seen champions of all ages, backgrounds, and abilities.

Young champions like Emma Raducanu shocked the world with their overnight success and veterans like Rafael Nadal continue to show they still very much have what it takes to challenge right at the top.

GiveMeSport Women has looked at the eight oldest players who have won a Grand Slam title since 1968.

Flavia Pennetta

Age: 33 years, 199 days

Pennetta won just one major tournament during her career and she had to wait until her final year on the court to do so.

The Italian turned pro in 2000 and won her first and only Grand Slam title 15 years later at the US Open.

She beat childhood friend Roberta Vinci in the first ever major all-Italian final.

Pennetta retired a month after her maiden title win.

Martina Navratilova

Age: 33 years, 263 days

Considered one of the greatest tennis players of all time, Navratilova won an impressive 18 Grand Slam titles during her career, including an all-time record number of Wimbledon titles.

She claimed her ninth title at The All England Club in 1990 when she was 33, making her the oldest woman to win a Grand Slam at the time.

Navratilova beat compatriot Zina Garrison in the final to round off her impressive tennis portfolio.

Andres Gimeno

Age: 34 years, 9 months, 19 days

Grand Slam: French Open 1972

By winning at Roland-Garros in 1972, Gimeno became the oldest Spanish player to claim a Grand Slam title.

He waited his entire career to win his first and only major tournament and retired a year later after injuring his meniscus.

Gimeno's French Open win also made him the oldest first-time Grand Slam winner ever.

Novak Djokovic

Age: 35 years, 1 month, 5 days

Grand Slam: Wimbledon 2022

Like Nadal, Djokovic is certainly showing no signs of slowing down in his career.

After winning two titles in 2021, the Serbian added a 21st Grand Slam to his tally earlier this year when he won his seventh Wimbledon final.

He beat Nick Kyrgios in the final to defend his crown for the fourth successive year.

Serena Williams

Age: 35 years, 4 months, 2 days

Grand Slam: Australian Open 2017

Williams holds the record for most Grand Slam titles won during the Open Era. With 23 to her name, she is unarguably one of the greatest players to ever grace the court.

In 2017, she beat sister Venus in the Australian Open final to become the oldest female player in history to win a major title. Her victory also marked the seventh time she has triumphed in Melbourne — a women's record for the Open Era.

Williams retired earlier this month after almost three decades on the court.

Rafael Nadal

Age: 35 years, 11 months, 19 days

Grand Slam: French Open 2022

The 'Big Three' may now have reached a point where retirement is looming, but Nadal is still a serious threat on the ATP Tour.

The King of Clay continued to live up to his nickname this year after winning his 14th French Open title.

Nadal beat Djokovic in the quarter-finals and Alexander Zverev in the semis before pipping Casper Ruud to the title.

With 22 major titles, the Spaniard boasts the most of any other male player in the Open Era.

Roger Federer

Age: 36 years, 5 months, 7 days

Grand Slam: Australian Open 2018

The recently retired Federer won his last Grand Slam at the Australian Open in 2018, becoming the second oldest male player to win a major tournament.

The Swiss legend did not drop a single set in the lead up to the final, where he beat Croatia's Marin Čilić in a five-set thriller.

Federer's victory in Melbourne took his overall tally up to 20 Grand Slam titles. He retired with a men's Open Era record of eight Wimbledon titles.

Ken Rosewall

Age: 37 years, 1 month, 24 days

Grand Slam: 1972 Australian Open

In 1972, Rosewall became the oldest ever Grand Slam champion after winning the Australian Open.

He won a total of eight major titles during his career — the Australian Open on three occasions and both the US Open and French Open twice.

However, despite reaching four Wimbledon finals, Rosewall was never able to add The All England Club to his portfolio and complete the set.

The stadium named after the Aussie native at the Sydney Olympic Tennis Centre has held the 2000 Olympic Games and the ATP Cup.
