At Wimbledon, John Isner and Nicolas Mahut battled for more than 180 games. At the Hopman Cup on Monday, they played for 22. The American prevailed in two sets, although he was a little worried.

“Had I lost that second set, it might have gone four hours, so I was lucky to finish it in two,” Isner told the Associated Press, presumably with a smile.

In fact, the pair was so fresh after their match, they went out and played mixed doubles later in the day. Isner’s team prevailed 2-6, 6-3, 10-8.

Only 135 games to go.
