Novak Djokovic led world number one Rafael Nadal after three sets of their Wimbledon semi-final when play was suspended until Saturday.
The Serb, a three-time Wimbledon champion, is ahead 6-4 3-6 7-6 (11-9).
They did not start their match until after 20:00 BST as they had to wait for Kevin Anderson's epic semi-final against John Isner to finish.
Wimbledon bosses closed the roof before the start but a 23:00 curfew meant the match will resume at 13:00 on Saturday.
While some ticket holders may have needed to leave for trains home, there was still a healthy crowd to watch two of the all-time greats on Centre Court.
