Jo lost 7-5 6-3 to the chinese girl and to put that into perspective the chinese girl then went onto lose love and one to a french girl in the FQR ranked herself outside the top 500. I think it's fair to say that a major breakthrough year is in danger of unravelling in the second half of this year. Ending on a positive note overcoming a losing streak of this magnitude can be the making of a player just ask Jankovic.
