LAURA ROBSON beat world No 4 Agnieszka Radwanska to reach the Madrid Open third round.
The shock 6-3 6-1 win was Brit Robson’s first triumph over a top-five player.
And it was all the more impressive when you consider Polish star Radwanska, the fourth seed, was runner-up at Wimbledon just last year.
World No 41 Robson, 19, will now face former French Open champ Ana Ivanovic or qualifier Chanelle Scheepers, who play their second-round game today.
