After a dire few months of football and rugby (seriously, let’s not even go there), we finally have something to celebrate: Juan Martín Del Potro is in the US Open semifinal.

Having gone into last night’s match against Swiss superstar Roger Federer as the underdog, Del Potro caused a major upset in the tennis world by beating the eight-time Wimbledon winner to secure his spot in the semifinal.

Memories of Del Potro defeating Federer in the 2009 US Open final are still fresh on everyone’s minds here. The so-called “Tower of Tandil” beat the Swiss in 4 sets  7-5 3-6 7-6 (10-8) 6-4 in a thrilling encounter, following Diego Schwartzman’s exit at the hands of Carreno Busta.

The first two sets were divided between the two, and it was during the third set that the game really began enthusing the scores of Argentines in the stands. Federer (3rd seed) took an early lead in the third set, but managed to let 4 points slip by. Del Potro was not so complacent finishing the set with a backhand (backhands having hindered him for years, following recurring surgeries on his wrist.)

In the fourth set, Federer became increasingly frustrated and complacent, whilst a cool Del Potro was able to cross the finish line. Federer, who claims to have felt unwell in the last fortnight due to a back injury, simply wasn’t his best, although that’s not to say he didn’t play well.

Del Potro on the other hand was a joy to watch. Despite consistent injuries he has been able to reach his first grand slam semifinal in four years.

Number one seed Rafael Nadal from Spain will take on Del Potro in the semifinal tomorrow.
