BIRMINGHAM, England — Maria Sharapova won twice within hours Thursday to advance to the quarterfinals of the Aegon Classic.

Extending her comeback after a 10-month layoff because of a shoulder injury and surgery, Sharapova needed only two minutes and five points to wrap up a 6-3, 6-4 victory against American Alexa Glatch in a second-round match suspended Wednesday by rain.
The unseeded Sharapova required little more than an hour to dispatch seventh-seeded Francesca Schiavone 6-1, 6-3.
Having reached her third quarterfinals in her third tournament, Sharapova would not say she was playing better than expected. She lost in the quarterfinals at Warsaw and the French Open.
“I’m just not serving full out as I did before the injury,” she said. “I don’t want to come out, after not playing for so long, hitting a really big serve. It gives me a chance to construct points.”
Sharapova will play Belgian teen Yanina Wickmayer, who defeated Roberta Vinci 6-1, 6-4.
The former Wimbledon champion is content to slowly work on her serve.
“I am just going to take it tournament by tournament and match by match,” Sharapova said. “I just want to get the percentage of first serves in. I don’t know when I am going to be at the level I was, or when I will be better. It may take time.”
Other third-round winners included Sania Mirza, who ousted fifth-seeded Anastasia Pavlyuchenkova 7-6 (3), 3-6, 6-2. Melinda Czink upset third-seeded Aleksandra Wozniak 6-7 (5), 7-5, 7-5.
