Andy Murray is through to the US Open semi-finals after defeating John Isner in four sets.
The first two sets proved relatively straightforward for the Scot, winning the first 7-5, and the second 6-4.
The big-serving American hit back in the third, winning 6-3.
The fourth set moved to a tie-break, with Isner not having lost a tie during the entire tournament, but Murray outplayed his opponent, winning 7-2.
The number four seed will face either Rafael Nadal after the Spaniard defeated Andy Roddick in straight sets.
