The 2019 Wimbledon final-set tiebreak began at 12–12 in the fifth set.
Novak Djokovic and Roger Federer had split the first four sets, so the championship came down to a deciding fifth set. Under Wimbledon’s rule introduced for the 2019 Championships, a final-set tiebreak was played when the score reached 12–12. Djokovic won that tiebreak 7–3, giving him a 13–12 fifth-set victory and the match.
The rule was a major change from Wimbledon’s traditional advantage-set format, in which players normally had to win the final set by two games. It followed concerns about exceptionally long matches, including the 2018 semifinals between Kevin Anderson and John Isner and Rafael Nadal and Djokovic.
This was the first Wimbledon men’s singles final to require a final-set tiebreak. The match lasted 4 hours 57 minutes, making it the longest Wimbledon final at the time. The 12–12 trigger should not be confused with the 6–6 tiebreak used in earlier Wimbledon sets or with different final-set rules at other Grand Slam tournaments.
