US Open 2018: Serena Williams beats sister Venus to reach fourth round
Serena Williams is chasing a seventh US Open singles title
Serena Williams made light work of her older sister Venus Williams to reach the US Open fourth round in New York.
The 23-time Grand Slam champion, looking to equal Margaret Court's all-time record of 24, needed just 71 minutes to win 6-1 6-2, BBC reported.
The American siblings, aged 38 and 36, were playing for the 30th time - but it was not much of a contest.
Serena Williams, who had a medical timeout in the first set, will play Estonia's Kaia Kanepi in the last 16.
Kanepi, 33, dumped world number one Simona Halep out in the first round and has not dropped a set so far at Flushing Meadows.
"This was my best match since I have returned," said Serena, who had time out of the game to give birth to her daughter last September.
By dropping just three games, Serena earned her joint biggest victory over Venus, alongside her 6-1 6-2 win at Charleston in 2013.
Venus said she thought it was her sister's best performance in their matches, because she did not "even get to really touch any balls".
"I don't think I did a lot wrong. But she just did everything right," Venus told a news conference.
"Obviously, that level is definitely where she's going to want to stay during this whole tournament."
My view: Nadal's match lasted 4 hours 22 minutes while Williams' match was 74 minutes and they get paid the same amount?, I don't get it, well it's tennis not football.
