Laura Robson knocks out Agnieszka Radwanska in Madrid

Great Britain's Laura Robson dropped just four games on her way to knocking world number four Agnieszka Radwanska out of the Madrid Masters this evening thanks to a 6-3 6-1 win.

Robson, who had struggled for form during a number of tournaments since the turn of year, claimed the decisive break in the first set to open up a 5-3 advantage, before going on to hold her next service game to take a one-set lead.

The second set proved to be even more comfortable for the 19-year-old, who went 4-1 up with two breaks of her Polish opponent's serve. A final break then followed as Australia-born Robson booked her place in round three of the competition in the Spanish capital.

Robson is currently ranked 38 in the standings, but a good run in the ongoing event in Madrid would likely see her move up a handful of places.
