Argentine Juan Martin Del Potro progressed to the last eight of the ATP Cincinnati Open after overcoming a tough opponent in the shape of Viktor Troicki of Serbia. In a close first set, neither player was able to make a significant break of serve. It was eventually settled via a tie-break with the sixth-seed from Argentina taking control and winning it 7-2. Troicki came out all guns blazing for the second set and managed to break Del Potro twice to level the match. However, Del Potro was too strong for the Serbian in the deciding set and brushed aside his opponent, breaking him twice to win the match 7-6, 2-6, 6-1. Del Potro will now face France’s Jeremy Chardy in the quarter finals after he produced an upset to beat third seed Brit Murray with a 6-4 6-4 scoreline.
Elsewhere, American and tenth seed Mardy Fish kept up his fine form in this tournament with a straight sets win against Radek Stepanek of the Czech Republic. Fish, who had not lost a set and had cruised his way to the fourth round, was to keep this record going with an impressive 6-3, 6-3 win against Stepanek, overpowering his opponent with another strong service game. Stepanek had threatened the Fish serve just twice, but the American was able to avert both break points and convert three of the eight he had forced. Fish will now face the imposing threat of Federer in the quarterfinals.
