Murray sees off Isner challenge to reach semis

Andy Murray became only the seventh man in the Open era to reach the semi-finals at all four grand slams in a single year with a gripping 7-5 6-4 3-6 7-6 (7/2) victory over giant American John Isner at the US Open today.

The world number four, who follows in the footsteps of Rod Laver, Tony Roche, Ivan Lendl, Roger Federer, Rafael Nadal and Novak Djokovic, looked to have Isner in his pocket at two sets up but the 28th seed hit back.
