As 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.

As things stand, Djokovic is just one major trophy away from tying the men’s record of 20 shared by Rafael Nadal and Roger Federer and will get his first chance to pull even with his rivals at Wimbledon, which starts in two weeks.

Djokovic became one of only three men — alongside Rod Laver and Roy Emerson — to have won each major tournament at least twice. And now, as the reigning champion at the Australian Open and French Open, Djokovic can set his sights on another rare achievement: He is halfway to joining Laver (1962 and 1969) and Don Budge (1938) as the only men with a calendar-year Grand Slam.
