Vasek Pospisil, the 13th seed proved to be unlucky for the ATP 500 Citi Open’s top seed Tomas Berdych. The Canadian knocked out of the Czech 6-2, 6-4. Pospisil’s serve was on song as he won 69 percent of his service points compared to 54 for Berdych, and the 13th seed broke the Czech four times in a convincing and mature performance.
John Isner’s conqueror Steve Johnson once again edged one of the game’s biggest servers in a final set breaker, taking out ninth seed Ivo Karlovic the 3-6, 7-6 (4), 7-6 (7).
Donald Young was another giant-slaying American as he upset 15th seed Denis Istomin 6-3, 3-6, 6-3.
Second seed Milos Raonic had a close encounter with Lleyton Hewitt, squeezing past him in two tiebreak sets, 7-6 (1), 7-6 (3).
Other seeds to make it through to the last eight were fourth seed Kei Nishikori who defeated Lukas Lacko in 3 sets, tenth seed Santiago Giraldo who thrashed Victor Estrella Burgos for the loss of just two games, seventh seed Kevin Anderson who saw off Malek Jaziri in straights and Richard Gasquet who sailed quietly through against American Tim Smyczek 6-3, 62.
