While older players in tennis can be appreciated, fans are usually looking for the next young phenom rising through the ranks.
While most tennis players leave singles competition by their early 30s and switch to doubles to preserve their physical health, a select few have held on longer and maintained a high level of play.
The oldest person to win a singles tennis Grand Slam in the Open Era (since 1968) is currently Ken Rosewall. The Australian-born tennis player won the 1972 Australian Open shortly after turning 37. The 2026 Australian Open final will feature the 38-year-old Novak Djokovic facing off with the 22-year-old Carlos Alcaraz.
Djokovic is already considered one of the greatest tennis players in history, but he could add another accomplishment to his ever-increasing list of accolades if he is able to beat Alcaraz.
Here is more on how Djokovic can make history by winning the 2026 Australian Open.
