Stanislas Wawrinka serves well to make the Quarter-Final in Ohio

Kei Nishikori only hit 6 winners in the opening set against Stanislas Wawrinka and made 14 unforced errors. Wawrinka won 82 % of the points when he made his first serve in the first set. Nishikori tried to keep up during the rallies but was totally outplayed. Wawrinka took the first set 6-3, breaking Nishikori for the third time to take the set. Wawrinka quickly has a 4-1 lead in the second set, leaving a frustrated Kei Nishikori at the other end of the net throwing his racket to the ground.

Nishikori then registered his fifth game of the match to barely stay alive in the match. But Wawrinka served for the match after an hour and 13 minutes to win 6-3 6-3. Wawrinka was consistent in the serve department in the entire match and Nishikori had no realistic chance of winning the match, let alone force the decing set. Meanwhile Milos Raonic needed 41 minutes to take the first set 6-4 against Tomas Berdych in their first meeting on the ATP World Tour.

Raonic looked the sharper man of the two in the first set. It soon became evident that he has more match-play than Berdych this season. Berdych tried to fight back by taking the second set 6-2, but lost the match 4-6 6-2 2-6. Raonic will play an in-form Stanislas Wawrinka in an anticipated Quarter-Final clash on Friday.
