Katie Boulter moved into the quarter-finals of the Japan Open after she beat Viktorija Golubic in less than an hour.

The British number two defeated her Swiss opponent 6-2 6-1 in Osaka and will face either Croatia's Antonia Ruzic or American Kayla Day in the next round.

Boulter saved a break point in the opening game but dominated from 2-2 in the first set, winning nine games in a row before Golubic took the penultimate game of the match.
