Novak Djokovic beat Karen Khachanov and the fading light to reach the Wimbledon quarterfinals.
As play was being suspended on other courts, Djokovic made sure he gets Tuesday off by breaking Khachanov for the seventh time to finish off a 6-4, 6-2, 6-2 win on No. 1 Court.
Juan Martin del Potro wasn't as efficient. His fourth-round match against Gilles Simon was suspended because of bad light after the fourth-seeded Argentine lost the third set.
Play was halted around 8:45 p.m. with del Potro leading 7-6 (1), 7-6 (5), 5-7.
