The crowd at Flushing Meadows were treated to a thrilling spectacle on September 4th as Juan Martin Del Potro mustered up enough strength to overcome Dominic Thiem in a five set thriller on the Grandstand Court. The Argentinean player was reportedly feeling unwell prior to the contest and considered pulling out of the competition but was rewarded for his persistence with a place in the Quarter Finals of the tournament. Del Potro’s only Grand Slam success came at the US Open in New York eight years ago when he saw off Roger Federer in five sets and the pair meet again in this year’s competition. He saved two match points in the 4th set and thanked the crowd for their support throughout the absorbing contest. The 22nd seed has struggled with injuries over the past couple of years and has seemingly never fully recovered from wrist surgery but he is hugely popular on the circuit and the crowd always enjoy his all-action displays. His passage to the final won’t be easy, however, with Roger Federer and potentially Rafa Nadal standing in his way. The 28-year-old admitted he was tired following the gruelling contest and will need to sufficiently recover in time to face the Swiss player. It wasn’t all plain sailing for Federer, who overcame German Phillip Kohlschreiber to reach the Quarter Final stage with the World Number 3 requiring a medical time out for an ongoing back complaint. Despite this concern, he hasn’t dropped a single set since the second round of the competition and admitted he is looking forward to taking on Juan Martin Del Potro again. The 36-year-old remains the second favourite for the title at 13/8 with Ladbrokes whilst Del Potro has been priced up as the fourth favourite behind Sam Querrey.
