Tied at 53-53 in the fifth set, the match has now entered its ninth hour.
That wasn’t the only record to get broken. Even though the match isn’t over, Isner, 25, of the U.S., and Mahut, 28, of France, have already played the most games in a match, while their fifth set is the longest in Grand Slam history.
Isner has served 93 aces, while Mahut had 84. Each broke Ivo Karlovic’s previous record of 51 aces in a men’s singles match set during a first-round match at Wimbledon in 2005.
“It’s amazing,” five-time women’s champion Venus Williams said in a news conference, after she beat Russia’s Ekaterina Makarova 6-0, 6-4. “It’s a marathon. It’s longer than a marathon.”
The match started yesterday and continued today after being postponed because of darkness after four sets.
