Wimbledon 2014: Serena Williams powers into third round

Serena Williams has hit 24 aces in her two matches at Wimbledon so far this year

Top seed Serena Williams needed only 49 minutes to reach the women's singles third round after overwhelming South African Chanelle Scheepers 6-1 6-1.

The five-time former champion was in complete control throughout against the 30-year-old world number 94.

Fifth seed Maria Sharapova was also a winner, beating Switzerland's Timea Bacsinszky 6-2 6-1.

"It was tough - there were a few close games but I was happy with the way I stepped up," she told BBC Sport.

"I was a bit nervous coming into the first round and I knew I needed to start better because she had a good first-round win.

"Court One is special to me so I am happy I settled in after the first round and took it from there.

"I'm not thinking about the last few years here, I'm starting from scratch and I want to be motivated to win this title."

Williams had a quick turnaround after playing doubles with sister Venus on Wednesday evening but still managed to serve eight aces and did not face a break point on her own serve.

"It is tough for me, every week I am always the favourite and that can be pressure, but I can deal with it and I'd rather be looked at that way," she told BBC Sport.

Williams will next face 25th seed Alize Cornet from France in the next round after she beat Petra Cetkovska of the Czech Republic 6-4 5-7 6-3.

Also through is 11th seed and former world number one Ana Ivanovic.

The Serb was a 6-4 6-0 victor over China's Jie Zheng, who was a semi-finalist in 2008 and her next opponent will be last year's beaten finalist Sabine Lisicki from Germany.

Lisicki was a 6-3 7-5 winner over Karolina Pliskova of the Czech Republic while Lisicki's compatriot Andrea Petkovic, the 20th seed also went through 6-4 3-6 6-1 against Romania's Irina Begu, despite needing treatment for a knee injury.

Eugenie Bouchard, the 13th seed from Canada, also advanced after a 7-5 6-1 win over Spain's Silvia Soler Espinosa while last year's semi-finalist Kirsten Flipkens of Belgium was a comprehensive 6-2 6-1 conqueror of another Spaniard Lourdes Dominguez Lino, winning in 50 minutes.

But one seed to fall was Spanish 15th seed Carla Suarez Navarro, who was beaten 7-6 (14-12) 5-7 6-2 by Kazakh player Zarina Diyas.
