Sabine Lisicki latest to withdraw from Brisbane International The popular German has been floored with a stomach virus making it impossible for her to play world No50 Stefanie Voegele in their second round match due at Queensland Tennis Centre today. Lisicki was the seventh seed for Brisbane and follows the withdrawal of sixth seeded - and newly engaged - Caroline Wozniacki , because she twinged her shoulder during practice. "And I just feel like for me it's more important that I really get 100 per cent and make sure that it doesn't get worse," Wozniacki said earlier this week. It's obviously very disappointing because I really look forward to playing here and starting off the year here. But with some good treatment and watch out for it a little bit over the next few days, I should be ready to play in Sydney. It was the same scenario for Australia's Ash Barty who withdrew last night from her second round tussle with world No. 4 Maria Sharapova. Barty's injury, suffered knocking over world No. 33 and former runner-up in Brisbane Daniela Hantuchova on Monday, is a little worse as she has a small tear in her left adductor muscle in her groin. The 17-year-old has withdrawn from next week's Hobart International as well as from Brisbane. But she said medical advice was she could be ready to play the Australian Open, starting January 13. "So it's pretty much just I need give myself, my body, 10 to 12 days to recover and hopefully be right for the Australian Open," Barty said. I mean, from the medical advice that I received, should be fine. So I just got to make sure that I do everything right and recover and do as much rehab as I possibly can. The men's draw in Brisbane has had some reshuffling as well. Australian wildcard and junior boys singles winner in Melbourne last year, Nick Kyrgios, had to withdraw with a shoulder injury before he was due to play is first match against fellow Aussie Lleyton Hewitt. And the Sydney International had its first casualty today, even though play does not start until Sunday, with the withdrawal of Spain's world No. 13, Nicolas Almagro. "Unfortunately Nicolas has been forced to pull out of Sydney with a shoulder injury," tournament director Craig Watson said. We wish him a speedy recovery and all the best for a successful Australian Open. We look forward to welcoming him back to Sydney in 2015.
