Novak Djokovic extended his streak of Wimbledon semifinal appearances to a record eight, outlasting No. 3 seed Felix Auger-Aliassime 7-6 (10), 3-6, 6-3, 6-7 (4), 7-6 (4) in a match that lasted 5 hours and 15 minutes.

It equaled the longest Wimbledon match of Djokovic’s career, the 2018 semifinal against Rafael Nadal, which was the second longest of his major career (2012 Australian Open final, also against Nadal, that went 5:53).

“With racket and a lot of heart,” Djokovic said on-court of how he won, “and management of the nerves.”

“These are the kind of moments I still play tennis for.”

At age 39, Djokovic becomes the oldest semifinalist at a major since Ken Rosewall at the 1977 Australian Open (Rosewall was 42).

Djokovic will face top-ranked and defending champion Jannik Sinner on Friday it what will be the No. 7 seed’s 55th career major semifinal appearance, the most by any man all-time.
