French Open: Sixth-seeded Novak Djokovic topped No.3 seed Alexander Zverev, last year’s finalist, in four sets 4-6, 6-3, 6-2, 6-4 to reach his record 51st career Grand Slam semifinal at the French Open.

The Serb's 51 major semifinals are already a record for men and just one behind Chris Evert for the overall mark — and his 13th at Roland-Garros. He is the second-oldest man in the Open era to reach the Roland-Garros semifinals after Pancho Gonzales in 1968.

The last time Djokovic faced Zverev, he was walking off the court solemnly after injury put a premature end to their Australian Open semifinal in January. But on Wednesday night in Paris, after more than three hours of battle on court Philippe-Chatrier, the 24-time Grand Slam champion rallied from a set behind to keep his quest for a record-setting 25th Grand Slam title going into the semifinals.
