Raducanu races into third round of US Open

EMMA Raducanu swept aside in-form qualifier Janice Tjen to reach the third round of the US Open.

If anyone knows the danger of qualifiers, it is Raducanu, who famously became the only one to win a grand slam title here four years ago.

Tjen, 23, must wait for another opportunity to try to make her mark, though, after being crushed 6-2 6-1 by Raducanu in exactly an hour.

It was even swifter than her first-round victory over another qualifier, Ena Shibahara, which had been her fastest grand slam win.

"I'm very pleased with how I played," said Raducanu. "I'm just looking forward to building day by day, doing my best."
