With her victory against Solana Sierra, Laura Siegemund became the oldest player to reach her first quarter-final at Wimbledon. No woman has ever been 37 years and 118 days old on her debut in the last eight in London. The German jubilantly said: "It's rare that you get a compliment for being old."
Ekaterina Alexandrova and Anastasia Pavlyuchenkova are two other women in the competition who have already cracked 30. And that emphasises that other qualities are required on grass. Strength, wit, and, above all, experience are absolutely necessary.
Siegemund certainly has the experience. She first played in the qualifiers for Wimbledon 14 years ago and made her main draw debut in 2015. A lot of energy has gone into this process, and now the Filderstadt native has a match-up with Aryna Sabalenka.
If, contrary to all expectations, she can win the title, she would be the oldest winner in well over 100 years.
Veterans impress in men's draw
But the old warriors have also done a good job in the men's tournament so far. Novak Djokovic and Marin Cilic have both managed to fight their way through to the round of 16 and could even play each other in a direct duel next if they were to win.
Grigor Dimitrov, on the other hand, has another chance at the age of 34 to show Jannik Sinner how an "oldie" plays on the grass. In 2014, the Bulgarian played his way to the semi-finals of the tournament.
Djokovic is probably the veteran with the best chance of winning the whole thing. A tournament victory on the hallowed turf would make the Serb - who recently celebrated his 100th title - the oldest Wimbledon winner since the beginning of the Open Era.
According to the bookmakers, the chances of achieving this are around 20 percent; not bad odds for a 38-year-old.
