Defending champion Andy Murray won a thrilling third-round contest against Italy's Fabio Fognini at Wimbledon as darkness fell around Centre Court.
The Briton, 30, won 6-2 4-6 6-1 7-5 after two hours and 39 minutes, with match point clinched at 20:57 BST.
Fognini, the 29th seed, had five set points to force a fifth set but Murray won five games in a row to seal a place in the last 16 for the 11th time.
Murray will play Frenchman Benoit Paire in the fourth round on Monday.
Fellow Briton Johanna Konta earlier reached the second week for the first time with a 6-4 6-1 win over Maria Sakkari of Greece.
