Federer wins marathon match for Olympic final

Swiss tennis maestro, Roger Federer beat Argentine Juan del Potro in a marathon semi final match to qualify for the Olympic final and have a chance to win the gold medal for the first time in his career.

The match lasted four hours 26 minutes, with the final set decided by a ding-dong tie break, ending 19-17 in Federer’s favour.

Potro won the first set at 6-3. In the second set, both players refused to yield to the other, and settled matters in a tie break.

The match was the longest three-set singles match in the Open era.

The seven-time Wimbledon champion, Federer was on the brink of a shock defeat on Centre Court after dropping the first set.

The match, 23 minutes longer than Rafael Nadal and Novak Djokovic’s Madrid semi-final in 2009, comes after Jo-Wilfried Tsonga took 66 games to beat Milos Raonic in the second round — the most seen in an Olympic three-setter.

The great escape means Federer, 30, is guaranteed at least a silver medal. In Sunday’s final, he will face world number two Novak Djokovic or Britain’s Andy Murray, who was beaten by Federer in last month’s Wimbledon final.

“I don’t think I’ve ever played as long a set in a best of three match,” Federer said. “The whole match was nearly four-and-a-half hours, so it was very physical at the end and so mental.

“It was very tough from start to finish. I got lucky in the second set to get back and then in the third it was so tough. I was calm but serving to stay in the match so many times is hard and it takes its toll.

“May a bit of fitness was the difference. I liked my attitude today, so I am very happy. I got my first (singles) medal for Switzerland.”

After a relatively barren two years by his standards, Federer is suddenly enjoying another of his dominant periods and this hard-fought victory showed his hunger for success remains as strong as ever.

Less than a month ago, Federer, a doubles gold-medallist with Stanislas Wawrinka in Beijing four years ago, was crowned Wimbledon champion for a record-equalling seventh time.

Now he is just one win away from completing the ‘golden slam’ of titles in all four majors and the Olympic singles gold.

Del Potro’s 2009 US Open final win over Federer was one of just two victories in 14 meetings with the Swiss, who came from two sets down to beat the 23-year-old in this year’s French Open quarter-finals.

But the big Argentine came out fighting, unleashing some hefty serves and punishing groundstrokes to keep Federer from establishing control.

After saving a break point in the third game, del Potro made Federer look increasingly uncomfortable and he secured the opening break for a decisive 5-3 lead when the Swiss was rushed into netting a backhand.

Federer was having to scramble just to hold his serve and he produced a pair of crucial aces to save two break points at 4-4 in the second set.

It needed a tie-break to decide the set and Federer finally began to dictate the tempo. He raced into a 4-1 lead and kept his nerve to induce a series of mistakes from del Potro that levelled the match.

A nerve-wracking final set saw five break chances wasted, two for del Potro and three for Federer, before the Swiss had a chance to serve for the match after breaking at 9-9.

Yet even then he couldn’t finish off del Potro, as incredibly the Argentine broke to love.

The drama continued as Federer squandered three more break points at 14-14 before he finally delivered the knockout blow with a break to lead 18-17.

Federer’s supreme fitness had kept him going and he wasn’t going to waste this chance, at last ending an all-time classic when del Potro netted on the second match point.
