Djokovic has won three titles at Roland-Garros among his men’s record 24 Grand Slams. He also owns prestigious winning head-to-head records against 22-time major winner Nadal (31-29) and 20-time major champion Roger Federer (27-23).

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.
