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.
