Cavaday upstages Keothavong

British number one Anne Keothavong crashed out of the AEGON Classic in Birmingham on Wednesday but 20-year-old Naomi Cavaday pulled off one of the best wins of her career to reach the third round.

Cavaday, a wild-card entry from Kent, gained a 7-6 (7-5) 2-6 6-4 second-round win over veteran Tamarine Tanasugarn, of Thailand, a player 250 places higher in the world rankings who was a Wimbledon quarter-finalist last year.

There were nine breaks of serve in a fluctuating match that finally swung the Briton's way when she broke her opponent in the seventh game of the deciding set and served out for a memorable victory over the number 12 seed.

Keothavong, the 25-year-old world number 49 who put out Sweden's Sofia Arvidsson in the first round to gain her first victory at Edgbaston for five years, was beaten 6-1 7-6 (7-5) by India's Sania Mirza.

Keothavong, the 11th seed, won only one game in the first set but looked to have turned the match around when she led 5-2 in the second and twice served to level.

She then twice dropped her serve before halting a losing four-game sequence to force a tie-break, which she lost 7-5, with 22-year-old Mirza - a former top-30 player now ranked 98th - saving no fewer than nine of her opponent's 11 break points.

Third seed Aleksandra Wozniak, of Canada, reached the third round thanks to a 6-4 6-4 win over Olga Govortsova, of Belarus.
