Last year’s US Open semi-finalist Stan Wawrinka was back in action after skipping the third round match and passed the test successfully by eliminating sixteenth seed Tommy Robredo. While the overall 6-3 head-to-head record still favors the Spaniard, he was defeated by the third seed title contender for the second consecutive time after also falling short in their last 16 encounter in Melbourne this January.
Stan had to dig deep in the opener when his opponent got just a service game away from taking the set at 5-4, but the Swiss clawed back before stealing another serve to avoid a tie-break. Such an outcome did not dent Robredo’s confidence as he clinched the single break of the set two and capitalized on it by eventually leveling the terms. The crucial moments of the clash would occur in the third set tie-break where Wawrinka stayed mentally strong to avert a double set point opportunity before preparing two on his own. He converted on the second one by putting away a magnificent forehand winner and went on to dominate the fourth set where he established a double break cushion by 5-1and held to love two games later for a 7-5, 4-6, 7-6 (7), 6-2 triumph. Robredo will be ruing missed chances as he converted only two of eight break points, whilst Wawrinka helped his cause by hitting 18 aces to the rival’s 5.
The last New York quarter-finalist in the top part of the draw is Kei Nishikori, seed number ten, who prevailed in a five-set thriller against fifth-seeded Milos Raonic. The Canadian smashed 35 aces past the opponent and went two sets to one ahead after winning the third set tie-break, yet the Japanese – he created 19 break points over the course of the clash – firmly stood his ground and broke late in the fourth set to force a decider. He maintained the upper hand to break midway through the final set and served out the match in first attempt to complete a fantastic comeback and win 4-6, 7-6 (4), 6-7 (6), 7-5, 6-4 after four hours and nineteen minutes of play. Nishikori was on the losing side in both previous meetings with Wawrinka.
