Novak Djokovic dug into his vast reserves of willpower to outlast Marcos Baghdatis and reach his first Wimbledon semi-final on Friday.
The Serbian fourth seed won 7-6, 7-6, 6-7, 4-6, 7-5 after five hours of riveting action on Court One.
Baghdatis produced a remarkable comeback after losing the first two sets on tiebreaks then trailing 3-0 in the third.
Djokovic looked exhausted in the fifth but stayed neck and neck with his Cypriot opponent and made the vital breakthrough at 5-5.
He then summoned all his energy to serve out the match and set up a reprise of his French Open semi-final against Spanish second seed Rafael Nadal, a match Nadal won on his way to the title.
In other quarter-final action, world No 1 Roger Federer woke up after a sleepy spell to overcome Juan Carlos Ferrero 7-6, 3-6, 6-1, 6-3 and reach the semi-finals at the grass court Grand Slam, where he is aiming for a fifth successive title, while French Open champion Nadal beat Tomas Berdych 7-6, 6-4, 6-2 to reach the semi-finals for the second successive year.
