Danish star Caroline Wozniacki has overcome a wildly erratic Sabine Lisicki to squeeze into the second round of the Australian Open.

The former world No.1 and 10th seed was baffled by Lisicki’s high-risk game before finally winning 2-6 6-3 6-3.

Wozniacki, who had beaten the German only once in three encounters going into the clash, struggled in the opening set and trailed 3-1 in the second before clawing her way back into the match.

Lisicki managed to hit a stunning 33 more winners than the Dane but was hobbled by her 57 unforced errors compared to Wozniacki’s eight.

Wozniacki should have an easier second round encounter when she meets the winner of the match between Czech Andrea Hlavackova and Croatian Donna Vekic.

Meanwhile, Japanese veteran Kimiko Date-Krumm has rolled back the years to pull off a major upset.

The 42-year-old crushed 12th seeded Russian Nadia Petrova 6-2 6-0 in just over an hour.

Italian seventh seed Sara Errani’s Open campaign also ended quickly as she was sent home when beaten 6-4 6-4 by Spain’s Carla Suarez Navarro.

Russia’s Maria Kirilenko, seeded 14, defeated American Vania King in straight sets 6-4 6-2.
