Novak Djokovic left the court to go the locker room for a little chat with himself after dropping the first two sets of the French Open final Sunday.

Part of him worried he was too diminished and depleted to overcome that deficit against his younger, fresher foe, Stefanos Tsitsipas. And another part of Djokovic insisted he would.

Guess which side was right?

Aided by flawless serving down the stretch, a determined Djokovic summoned his imperious best and came all the way back to beat Tsitsipas 6-7 (6), 2-6, 6-3, 6-2, 6-4 for his second championship at Roland Garros and 19th Grand Slam title overall — one away from the men’s record shared by Roger Federer and Rafael Nadal.
