Meanwhile, Americans Bob and Mike Bryan won a record 13th men's grand slam doubles title on Saturday, thrashing Dutchmen Robin Haase and Igor Sijsling in Melbourne.

The twin brothers moved past the 12 won by the Australian pair John Newcombe and Tony Roche in the 1960s and 1970s as they triumphed 6-3 6-4 in less than an hour.

The 34-year-olds, who won the Olympic title last year, have now played in 23 grand slam finals.
