Novak Djokovic hopes of becoming the first man to complete the Golden Slam were dashed on Friday after he was unexpectedly beaten by Germany's Alexander Zverev in the singles semi-finals at the Tokyo Games on Friday.
The Serbian's 1-6, 6-3, 6-1 defeat also ended his dream of winning an Olympic singles gold medal, the only major honour missing from his long list of accolades.
The world number one had arrived in Tokyo gunning for the Golden Slam -- winning all four majors and Olympic gold in the same year -- after triumphing at the Australian Open, Roland Garros and Wimbledon in 2021.
Djokovic, who won singles bronze at the 2008 Beijing Games, appeared to be on course for an easy victory on Friday when he claimed the opening set for the loss of just one game and then went up a break midway through the second.
But world number five Zverev managed to find another gear, breaking back and reeling off eight games in a row to take the set and take a commanding lead in the decider.
Zverev sealed the victory with a winner to become the first German man to make an Olympic tennis final since Tommy Haas won silver at the Sydney Games in 2000.
He will play Karen Khachanov of the Russian Olympic Committee in the championship match.
