Former world number one Caroline Wozniacki made it through to the third round at Wimbledon with a topsy-turvy 6-1, 7-6 (8/6) win over Denisa Allertova on Thursday.
The Danish fifth seed took just 23 minutes to secure the first set but the second was a totally different affair as the Czech world number 83 showed the form that led her to break the top 100 for the first time earlier this year.

Wozniacki, 24, next faces Italian 31st seed Camila Georgi in the last 32. Wozniacki has reached the fourth round four times in eight appearances at Wimbledon but has never gone beyond the last 16. Allertova, 22, was making her Wimbledon debut and initially looked out of her depth facing the world number five on the 1,000-capacity Court 12 in only her second tour-level match on grass.
Wozniacki raced into a 5-0 first set lead but Allertova escaped the tennis players' dreaded 'bagel' - a 6-0 thrashing. However, Allertova looked a different player in the 63-minute second set, throwing in drop shots and hitting winners but Wozniacki, a two-time US Open finalist, came out best in the tie-break.
