PARIS—A crucial moment arrived more than 2 1/2 hours into Novak Djokovic’s 4–6, 6–3, 6–2, 6–4 French Open quarterfinal victory over Alexander Zverev. It was the fourth set, and Djokovic led, but Zverev was in possession of a break point and a chance to get back into Wednesday’s match.
They engaged in a 41-stroke exchange, the longest of a buggy and breezy night, and Djokovic came out on top, smacking a forehand winner. He stayed in place afterward, breathing heavily, with hands on hips, scanning the standing ovation from thousands of Court Philippe-Chatrier spectators. He soon held serve for a 4–2 lead in that set and was back on track.
