Laura Robson secured the biggest win of her career with a shock victory over former world number one Kim Clijsters in round two of the US Open.
Clijsters was hoping to mark her
final event before retirement
with a fifth major title and a fourth in New York, where she
last lost in 2003.
But 18-year-old Robson overpowered the Belgian, 29, to win 7-6 (7-4) 7-6 (7-5) in 126 minutes on Arthur Ashe Stadium.
The British number three faces Chinese ninth seed
in round three.
Na won the 2011 French Open but is unlikely to faze Robson after this incredible result.
“It was such a good atmosphere,” said the Londoner. “I didn’t have any expectations going into the match because she’s such a good player and so experienced.
“I’ve had so many tough matches against top players that I knew the level was there, I just had to keep it for the whole match.
“Kim has been such a great player for so many years and a role model for all the younger girls coming up.”
gave Maria Sharapova a scare
at Wimbledon last year and went one step further against Clijsters.
The world number 89 attacked her 25th-ranked opponent throughout to secure a historic and richly deserved win.
Her serve was broken in game four of the first set and Clijsters swiftly moved into a commanding position at 5-3.
But that seemed to encourage Robson to go for her shots and two stinging forehands up the line helped her break back.
She pinned Clijsters behind the baseline and hit forehand and backhand winners from all parts to force a tie-break.
Robson continued to pile the pressure on Clijsters and the Belgian put a return long to hand over the initiative.
Nerves were evident early in the second set as the Briton sent down a double-fault on break point and her opposite number returned the favour in the very next game.
Both players scrambled out of trouble before a stunning crosscourt backhand gave Robson two match points at 7-6 (7-4) 6-5.
Clijsters held firm with a cool drive volley and ace, yet it was Robson who showed greater composure in the tie-break.
Robson earned a third match point with an unstoppable forehand, and wrapped it up when Clijsters looped a backhand long.
It was more evidence of the Olympic mixed doubles silver medallist’s encouraging relationship with new coach Zeljko Krajan, following an impressive
