Berdych and Hewitt through, Haas out of US Open

Tomas Berdych served notice of his intent to Andy Murray and all the title favourites with a demolition of Julien Benneteau to reach the fourth round of the US Open.

There the Czech will play Stanislas Wawrinka, and if he gets past the ninth seed then a clash with third seed Murray is likely to await in the quarter-finals.
