Novak Djokovic became the oldest man in 34 years to reach the fourth round of the US Open on Friday night, overcoming lower back issues to defeat Cameron Norrie 6-4, 6-7 (4), 6-2, 6-3. Not since Jimmy Connors’ straight-sets victory over Karel Nováček in 1991 has a man older than 38 years and 99 days claimed a third round win at Flushing Meadows. . . . #djokovic #cameronnorrie #usopen (📸 Mike Stobe/Getty Images)
