Former world No.1 Caroline Wozniacki is out of Wimbledon after losing to Shuai Zhang in the third round.

The Danish 14th seed looked to be cruising, leading 4-0 in the opening set, before a stunning collapse in which her Chinese opponent won 12 of the next 14 games to earn a 6-4 6-2 win.

Wozniacki, the 2018 Australian Open winner, was not happy on court No.3, regularly complaining about line calls and Hawkeye, as Zhang followed up her first-round win over 23rd seed Caroline Garcia.
