US Open: Serena Williams beats Maria Sharapova inside an hour as Konta and Evans also reach second round

Serena Williams triumphed over Maria Sharapova in a US Open first-round contest as one-sided as their 15-year rivalry.
Williams, the 23-time grand slam champion, has now won 20 of their 22 meetings following a thumping 6-1 6-1 victory.
It was the pair's first encounter since January 2016, and was all the more eagerly-anticipated after Williams pulled out of a scheduled meeting at last year's French Open through injury.
Sharapova is nowhere near the player who beat Williams in the 2004 Wimbledon final - and also won their next match the same year - but despite the scoreline she did not play at all badly.
The Russian, 32, got a healthy 73 per cent of her first serves in. One fierce cross-court winner on the run even had Williams applauding.
But Sharapova could barely lay a glove on Williams, who turns 38 this month and remains tantalisingly within touching distance of Margaret Court's record of 24 major titles.
Victory was wrapped up when a Sharapova return floated long after only 59 minutes.
