Madison Keys became the sixth top-10 seed to be eliminated from the women's singles at Wimbledon, as she was beaten in straight sets by 37-year-old Laura Siegemund.

The Australian Open champion followed Coco Gauff, Jessica Pegula, Jasmine Paolini, Zheng Qinwen and Paula Badosa in being eliminated, losing 6-3 6-3 in just over 90 minutes on Friday.

Keys struggled from the baseline from the very start of a match that began with a series of gruelling, back-and-forth games.

Siegemund earned two of three straight breaks to get her nose in front early on, then Keys missed an opportunity to break back and was punished with another break, as Siegemund took the opener.

The German – the oldest player remaining in the draw – was broken in the first game of the second set, but that only spurred her on to greater heights.

Some wonderful movement and a series of classy touches at the net helped Siegemund register back-to-back breaks, and though she squandered three match points on Keys' serve at 5-2, she made no mistake at the fourth time of asking when on serve, as Keys' return spun wide.

Siegemund will now face Solana Sierra in the round of 16, after the Argentinian became the first lucky loser to reach the fourth round of the women's singles in the Open Era.

Also into the fourth round is home hope Sonay Kartal, who beat French qualifier Diane Parry 6-4 6-2, becoming just the fifth British woman to reach the last 16 this century after Laura Robson, Johanna Konta, Emma Raducanu and Heather Watson.

Kartal will face Anastasia Pavlyuchenkova – conqueror of Naomi Osaka – for a quarter-final place, and she will not underestimate any opponent.

Kartal said in her on-court interview: "Everyone in this tournament is an unbelievable player, but I respect everyone the same. I will try my best to approach the next match in the same way. I try to stay calm off court, but I am so grateful to get the win today."

Data Debrief: Siegemund follows in Navratilova's footsteps

It is fair to say Siegemund is enjoying something of a renaissance at this year's Championships.

She is just the sixth woman in the Open Era to reach the last 16 at Wimbledon after turning 37, after a series of tennis icons in Billie Jean King, Virginia Wade, Martina Navratilova, Venus Williams and Serena Williams.

At the age of 37 years and 118 days, she is also the oldest woman to defeat a top-10 player at SW19 since Navratilova in 1994, when she beat Jana Novotna in the quarter-finals.
