Andy Murray maintained his perfect record against Feliciano Lopez to reach the second week of the Australian Open without dropping a set.
The fourth seed had beaten Lopez in all seven of their previous meetings but this was seen as the first real test of Murray's form following back surgery.
It was a test he passed with flying colours, playing a superb tie-break at the end of a tight first set and then pulling away to win 7-6 (7/2) 6-4 6-2.
And Murray will be a hot favourite to reach the quarter-finals given he next meets 119th-ranked lucky loser Stephane Robert.
