BIRMINGHAM, UK - It was a mixed day for the seeds at the AEGON Classic on Wednesday - and a frustrating one for most of the players in the field as rain again wreaked havoc with the schedule. Among those whose matches were halted by the drizzle was Maria Sharapova, who held match a point against Alexa Glatch but must now see to her unfinished business on Thursday.

Also in the second round, third-seeded Canadian Aleksandra Wozniak beat the weather and Olga Govortsova of Belarus, 64 64. But sixth seed Ekaterina Makarova fell to Stefanie Voegele in three sets; next up for the 99th-ranked Swiss player is British wildcard Naomi Cavaday, who scored the best win of her career rankings-wise by ousting world No.47 Tamarine Tanasugarn, the No.12 seed, 76(5) 26 64.

"She has a great record on grass and has a great record full stop," said Cavaday of the Thai veteran. "The biggest thing today was my belief. I never stopped believing in myself and that's what got me through during the tough times in the match."

Eleventh seed Anne Keothavong, the British No.1, was less successful than her compatriot. Seeded in Birmingham for the first time, the Londoner got off to a slow start against India's Sania Mirza, and despite going up a break in the second set couldn't quite force a third. Former world No.27 Mirza, currently ranked 98th, advanced with a 61 76(5) scoreline.

"I didn't expect to a play my best tennis at this tournament because it's my first grass court tournament," Keothavong said. "I got off to a slow start and I was pretty flat. I had my chances in the second set but I didn't close it out.

"Sania's a quality opponent and she's dangerous when she gets a good strike on the ball. I was a bit passive and I was too far behind the baseline at times - playing a bit of clay court tennis instead of grass court tennis. There are plenty of things for me to work on before Eastbourne and Wimbledon."

Earlier in the day several first round matches were completed, the winners including No.15 seed Aravane Rezai; Russian Alla Kudryavtseva, who had saved four match points against British qualifier Naomi Broady before play was suspended on Tuesday; and qualifiers Chanelle Scheepers and Lilia Osterloh.

The first appearance by top seed Zheng Jie, who is drawn to play another Brit, Melanie South, was postponed until Thursday due to the weather. Sharapova and Glatch will resume their match with the score at 63 54 in the Russian's favor, but with the American holding game point.
