Novak Djokovic has become the oldest man to reach the quarter-finals of all four Grand Slams in a single season, sealing his place in history with a straight-sets win over Jan-Lennard Struff at the US Open, Reuters reported.
The 38-year-old Serbian dominated 6-3, 6-3, 6-2, breaking serve six times and winning nearly 80 percent of his first-serve points. The victory marked his 64th Grand Slam quarter-final and keeps alive his bid for a record-extending 25th major title.
Though he received treatment for his right arm during changeovers, Djokovic showed little sign of slowing down, comfortably outclassing Struff, who was making his first appearance in the tournament’s last 16, according to Reuters.
