Murray and Huber had the upper hand in both sets as they claimed a 6-3 6-4 semi-final victory over Murray's former men's doubles partner Butorac and his American partner.

Murray won the mixed doubles title at Wimbledon last year with Jelena Jankovic and will aim to repeat the feat against fifth seeds Cara Black and Leander Paes in Thursday's final.

Murray and Huber reached the last four at Flushing Meadows 12 months ago and at Wimbledon earlier this summer.

"We played a solid match and came through it well." said Murray.

"We made semis here last year and its good to go one better, but we will be looking for another win in the final."
