Talented and tenacious as they come, Novak Djokovic was not about to concede a thing after dropping the first two sets of the French Open final against his younger, fresher foe, Stefanos Tsitsipas.

Djokovic looked diminished and depleted at the outset Sunday. By the end, he was at his imperious best.

The top-seeded Djokovic came all the way back to beat the fifth-seeded 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.

Djokovic is now just one major trophy away from tying the men’s record of 20 shared by Rafael Nadal and Roger Federer. And reigning Australian Open champion Djokovic now stands halfway to a calendar-year Grand Slam, something no man has accomplished since Rod Laver in 1969.

The 34-year-old Djokovic eliminated 13-time French Open champion Nadal — a challenge the Serb likened to scaling Mt. Everest — in a semifinal that lasted more than four hours Friday night.
