Serena Williams was at her ruthless best as she dumped her older sister out of the US Open, securing a 6-1 6-2 win over Venus on Friday night.
The 23-time Grand Slam champion certainly didnt go easy on her sibling, producing a performance she described as her best since her return from pregnancy earlier this year.
While the result never appeared in doubt, there was a sticky moment on court for the 36-year-old early in the match as she rolled her ankle.
Though Serena seemed relaxed about the situation, she admitted she will be monitoring it closely on Saturday ahead of her last-16 tie with Estonias Kaia Kanepi.
I actually roll my ankle a lot so I was trying to get it as taped as much as I could and well see how it is tomorrow, she said in her on-court interview.
Her physical condition may be of some concern, but Serena was delighted with the manner in which she conducted her business.
This was my best match since I returned, she added. I worked for it. I worked really hard these last three or four months.
Thats life, you have to keep working hard no matter ups or downs you have. Thats what Ive been doing.
Of course, competing against a family member adds an extra dimension to proceedings and Serena alluded to how hard it can be to take on her sister.
Its not easy, the American continued. Shes my best friend. She means the world to me and is so supportive of my career.
Every time she loses I feel like I do. Its a tournament and we all know theres more to life than playing each other and just playing tennis.
I hope my dad didnt watch. Its his two daughters playing, its not easy. I know hes probably feeling as nervous as we both were.
