Grand Slam Serena

Serena Williams wins in 59 minutes

Serena Williams admitted her quest to complete a calendar year Grand Slam is on her mind after advancing into the third round of Wimbledon.

Five-time Wimbledon champion Williams, 33, set up a third-round tie against Britain's Heather Watson by beating Hungarian Babos in less than a hour.

Having won the Australian Open and French Open this year, the 33-year-old is bidding to add the Wimbledon and US Open crowns and become the first woman to complete the full set of titles since Steffi Graf in 1988.

"Obviously it's on my mind and it's something I want to do, but there's a reason it's rarely done," Williams said.

"I would have to win in a really tough draw here and I would have to win the Open. That's not really easy."

Williams broke her 93rd-ranked opponent in the opening games of both sets and never looked in any danger despite having to save two break points in the fourth game of the second set.

"I'm definitely playing well," she said.

"Heather Watson plays so well on the grass and she loves playing at home. I never like playing the Brits at home so once again I have my work cut out."

Sharapova keeps her cool

Sharapova: Best five shots v Hogenkamp

Court two may have a reputation for being a 'graveyard of the seeds' but Sharapova made sure she would not be added to its long list of victims.

Sharapova served eight double faults but took 65 minutes to beat her Dutch opponent.

The 2004 champion, had too much accuracy and potency to her shots as she overwhelmed her opponent.

The Russian, 28, will face Irina-Camelia Begu in the next round after the Romanian beat Ukraine's Lesia Tsurenko 7-5 6-7 (4-7) 7-5.

"It's much warmer in my hometown of Long Boat Key, Florida," said Sharapova. "There's some cloud coverage. I think I've trained quite long in the heat over there.

"I think understanding it's going to be warm, not going for too much because you want to make the points quicker because of the heat and just being a little bit smarter out there is important."

Sister act?

Venus Williams, 35, joined younger sister Serena in the third round - and the two could meet in round four.

The Williams sisters have each won the title at the All England Club five times, but Venus has not done so since 2008.

The sisters have played each other 25 times, with Serena winning 14.

Time out

Ana Ivanovic, a former French Open champion and world number one, lost to 158th-ranked Mattek-Sands to become the second-highest seed to exit the women's draw after Simona Halep was beaten on Tuesday.

It is seven years since the Serb clinched the title at Roland Garros, although she reached the last four on the Paris clay a month ago.

"She played well," said Ivanovic. "She was aggressive. She was hitting lots of winners off the forehand side.

"I'm looking forward to having some time off and do proper preparation because that's what I've been lacking.

"I've been playing catch-up in that area for a while. I just need time to first rest, refresh and then work hard for it."
