Overview

• Djokovic won 6-4, 6-7 (4), 6-2, 6-3 after taking an off-court medical timeout late in the first set for a lower-back issue.
• He struck 18 aces and called it his best serving performance of the tournament, helping him pull away in sets three and four.
• At 38, he is the oldest man to reach the US Open fourth round since Jimmy Connors in 1991 and he now has a record 192 hard‑court Grand Slam wins, surpassing Roger Federer.
• The victory tied Djokovic with Federer for the most fourth‑round appearances at majors at 69, adding to his milestone chase.
• He faces Germany’s Jan‑Lennard Struff in the last 16, and Norrie’s loss means no British singles players remain in the tournament.
