Andy Murray survived a near four-hour epic against Spain's Feliciano Lopez to reach the fourth round of the US Open in sweltering conditions in New York.
The third seed has a great record against Lopez but this match was tight from the start and Murray looked in trouble in the fourth set as he began to struggle in the heat.
But he hung tough and eventually edged his third tie-break of the match to come through 7-6 (7/5) 7-6 (7/5) 4-6 7-6 (7/4) and set up a last-16 clash with either Milos Raonic or James Blake.
Andy Murray has won his third-round match at the US Open against Spain's Feliciano Lopez 7-6 (7/5) 7-6 (7/5) 4-6 7-6 (7/4).
