Miami, United States, 19 March 2013 | tennis.com.au

It was a day to forget for the Australians in Miami qualifying, with all four Aussies in action on Monday going down in the opening round.

Casey Dellacqua drew No.3 seed Lauren Davis of the US, and despite building a handy lead on Stadium Court, was unable to hold off the fast-finishing 19-year-old.

Dellacqua eventually lost 1-6 6-4 6-1 to the world No.81 in two hours, struggling on serve and forced to face 13 break points throughout the match.

Earlier in the day at Crandon Park, Dellacqua’s compatriots Anastasia Rodionova and Jarmila Gajdosova were ousted, also dealt tough draws.

Rodionova battled for almost three hours before being beaten by former world No.35 Sesil Karatantcheva 6-1 5-7 7-6(3), while Gadjosova, a wildcard into qualifying, fell to recent Malaysian Open winner and No.7 seed Karolina Pliskova 7-6(3) 6-1.

On the men’s side, Matt Ebden found emerging American Steve Johnson too much to overcome, falling to the 23-year-old 6-4 7-6(5) in one hour and 29 minutes.

Australia has three representatives – Bernard Tomic, Marinko Matosevic and Lleyton Hewitt – in the main draw.

Wildcard Hewitt faces Portugal’s Joao Sousa, while Tomic and Matosevic have both drawn qualifiers in their opening matches.

Australia’s top-ranked player Sam Stosur withdrew from the Sony Open yesterday due to a right calf injury.
