Petra playing Osaka. Interesting that she decided to stay in Asia, considering she hasn't had a good season outside Europe this year.
She will play Polona Hercog, the girl she defeated at 2nd round of qualifying of Wimbledon this year. This time they will battle on HC, so I think it will definitely be harder this time round.
She is ranked #76, so if Petra can beat her, it will be her first Top 100 win SINCE Wimbledon and first Top 100 HC win since her comeback.
Good luck, Petra.
