Robson knocked out in Miami

Laura Robson passed up the chance to become British number one on Friday night as she was beaten in three sets in the second round of the WTA Sony Open by Alize Cornet.

The 19-year-old started well but, in a match which lasted two hours 36 minutes but was stretched over seven hours due to rain delays and power cuts in Miami, the 32nd-seeded Frenchwoman eventually emerged a 5-7 7-5 6-1 winner.

World number 36 Cornet, who wrapped up the win with a run of five straight games, will face American Lauren Davis in round three.
