2012 Olympics tennis: Federer beats del Potro in epic semifinal
London: World No.1 Roger Federer reached the Olympics men`s singles tennis final after beating Juan Martin del Potro of Argentina in an epic match on Friday.
The epic third set lasted for 36 games until the Swiss legend converted his second match point for a 3-6, 7-6(5), 19-17 win in the longest match ever seen in Olympic tennis.
After losing the first set, the seven-time Wimbledon champion was on the verge of defeat in the second but saved it on a close-fought tie break.
The players spent four hours and 26 minutes on the court, 29 minutes longer than the second-round match between France`s Jo-Wilfried Tsonga and Canada`s Milos Raonic, who still hold the record for the longest third set, which went to 48 games.
In the Olympic final, Federer will face either second seed Noval Djokovic or Britain`s Andy Murray.
Del Potro will play the loser of that match for the bronze medal.
