Britain's Jamie Murray moved a step closer to an eighth Grand Slam doubles title as he and Bethanie Mattek-Sands reached the Australian Open final.

Murray and American Mattek-Sands saw off Australian wild cards Astra Sharma and John-Patrick Smith 6-3 7-6 (7-4).

They will face fifth seeds Barbora Krejcikova from the Czech Republic and Croatia's Nikola Mektic on Saturday.

"There was a lot at stake. For us to be in the final is really exciting," said Murray, 33.

The Scot is chasing a sixth mixed doubles title to add to the two men's doubles majors he won at Melbourne Park and the US Open in 2016.

Murray and Mattek-Sands have already won two mixed doubles titles together, with both coming at the US Open.
