Debutant Danielle Collins launched into a maiden Grand Slam semifinal courtesy of a 2-6 7-5 6-1 comeback triumph over world No.44 Anastasia Pavlyuchenkova on Tuesday afternoon.
The 25-year-old, without a major main draw victory before this trip to Melbourne, built on her standout demolition of 2016 champion Angelique Kerber in the fourth round to fight through.
“This has all been a really incredible experience. This time last year I was playing a challenger in Newport Beach,” revealed the unseeded American. “I think I'm really embracing it.”
