Johanna Konta followed up her stunning victory over Serena Williams with another brisk triumph yesterday, downing US teenager Sofia Kenin 6-1, 6-4 to reach the quarter-finals of the WTA hardcourt tournament in San Jose.

Konta, who won her first WTA title at this event back in 2016, showed no sign of a let-down after handing 23-time Grand Slam champion Williams the most lopsided defeat of her career — 6-1, 6-0 on Tuesday.
