Jamie Murray and Neal Skupski have been knocked out of the Australian Open men's doubles, losing a final-set tie-break to American pairing Sam Querrey and Steve Johnson.

The British 14th seeds saved six match points but eventually lost 4-6 7-6 (7-5) 7-6 (14-12) in the second round.

There was better news for Neal's brother Ken who teamed up with Mexican partner Santiago Gonzalez to beat second seeds Marcelo Melo and Lukasz Kubot 7-5 7-6 (7-4) and reach the third round.

Another Briton to go through was Joe Salisbury who won alongside American Rajeev Ram. The 11th seeds defeated Tennys Sandgren and Jackson Withrow 6-3 6-3.
