It is Kristyna Pliskova's second time to be in the second round of the Australian Open, replicating her success in 2013. This time, she upset home favorite, Samantha Stosur (#27) 64 76(6).
She will next meet Monica Puig of Puerto Rico (#52) in the second round. She has a good chance of reaching the third round here for the first time.
It's also the fifth time she has reached the second round or deeper in a grand slam.
