Tokyo, Japan, 24 September 2013 | tennis.com.au

Sam Stosur is through to the third round of the Toray Pan Pacific Open after staging a second set comeback against Japanese veteran Kimiko Date-Krumm.

Stosur won 6-3 7-6(2) in one hour and 44 minutes to set up a meeting with Czech Lucie Safarova in the final 16.

But for a while it looked as if she might not make it; she found herself down 3-5 in the second set before recovering, and served to stay in the set before sending it to a tiebreak.

Once there, the Australian used crushing body serves and her heavy forehand to full effect, forcing errors from Date-Krumm and silencing the excitable home crowd at Ariake Coliseum.

The 12th seed next finds herself up against Safarova, a dangerous left-hander whom she owns a 2-6 head-to-head record against.

Safarova has won their past three encounters, all in straight sets.
