World number one Serena Williams is keen to keep her concentration ahead of a potential Wimbledon reunion with sister Venus.
Serena Williams is determined to stay focused despite the increasingly likely prospect of a fourth-round clash with elder sister Venus at Wimbledon.
The world number one delivered a big statement of intent as she continued her bid to reclaim the Wimbledon title for the first time since 2012, powering to a 6-4 6-1 win over Timea Babos on Wednesday.
Serena racked up 12 aces and 23 winners on her way to a routine victory on Centre Court, setting up a third-round clash with Great Britain's Heather Watson.
Victory in that match and a win for Venus over Alexsandra Krunic would see the siblings, who share 10 Wimbledon singles titles, face off for the first time since the Rogers Cup last August.
Venus emerged victorious in three sets on that occasion.
"I always root for Venus," Serena said. "She's been through a lot in her career and she's really playing well this year and has had some wonderful wins and some good results so, yeah, I'm always rooting for her.
"She's been playing really well. Obviously I'm really happy for her and I always want to see her do great, but she poses a big threat for me, so I'm just trying to stay focused."
A sixth Wimbledon title would see Serena hold all the major singles titles at once for the second time in her career, and keep her on course for a first calendar Grand Slam.
"Obviously it [the calendar Grand Slam] is on my mind, but I will have to win in a really tough draw here and I would have to win the [US] Open, and that's not really easy," Serena added.
"Obviously it's something I want to do but at the end of the day there's a reason it's rarely done."
Asked about Watson and her home advantage, Serena said: "I feel like she does really well on grass. She played well at Eastbourne a couple of times and she's doing well on grass.
"She had a really good win today [against Daniela Hantuchova] so I know it's not going to be easy for me and she has nothing to lose and has good form.
"I think [the home crowd] will be a huge advantage for her. It's going to be a great big match for us both.
"I am used to playing against a lot of local people, it doesn't matter what country it's in. Hopefully that will help me a little bit and the home court will probably help her a little bit."
