del Potro Upsets Andy Murray to Give Argentina a Commanding Davis Cup Semifinal Lead

Juan Martin del Potro continues to pick off tennis’ top-ranked players…

The 27-year-old Argentine tennis player ended Andy Murray‘s 14-match winning streak in the Davis Cup, coming through with a 6-4, 5-7, 6-7 (5), 6-3, 6-4 victory in 5 hours, 7 minutes to gain a measure of revenge after losing the Olympic final to Murray last month.

It was the longest match of both players’ careers.

Del Potro’s win leaves Argentina thisclose to its first Davis Cup final since 2011 after taking a 2-0 lead over defending champion Great Britain thanks to singles wins by del Potro and Guido Pella in the semifinal on Friday.

Pella beat Kyle Edmund 6-7 (5), 6-4, 6-3, 6-2, meaning the Argentines can clinch victory with a day to spare in Glasgow if they win the doubles on Saturday.

Federico Delbonis and Leonardo Mayer are scheduled to play the Murray brothers, Andy and Jamie.

Whether Andy Murray plays is open to question.

Being taken the distance against Del Potro was exactly what Murray didn’t need at the end of his long summer of tennis in which he won both the Wimbledon and Olympic titles for the second time. He looked almost out on his feet at times in an energy-sapping final set, and couldn’t handle the barrage of forehand shots by the rejuvenated Del Potro.

”I’m very proud of how I fought, I did fantastic,” Murray said. ”I fought for every point, tried as best as I could. That’s all you can do.

”It was very fine margins. That happens in tennis and sport sometimes. It could have gone either way.”

del Potro gained the crucial break in the fifth set at the third opportunity, reaching Murray’s angled volley with a forehand winner down the line to go 4-3 ahead, and he served out for the match, clinching victory with an ace and a big growl.

Murray had never previously lost a home singles match in the Davis Cup.

del Potro, the 2009 US Open champion, is a force in tennis once again after returning from three wrist operations that nearly ruined his career. He’s Argentina’s top player but is ranked a lowly No. 64 on his comeback trail, meaning he had to play Murray in the opening match.

”I cannot imagine this moment in my career,” del Potro said. ”This was the type of match I was missing when I was at home.”

Argentina is playing its 11th Davis Cup semifinal in 15 years. The south American country has never won the team event, finishing runner-up in 1981, 2006, 2008, and 2011.

del Potro previously defeated Rafael Nadal and Novak Djokovic in the Olympics this summer, before losing to Murray in the final.
