France's fifth seed Marion Bartoli overcame an injury which reduced her to tears to beat American Jill Craybas 2-6, 6-0, 6-1 in the second round of the Auckland WTA Classic on Wednesday.

Bartoli wept during the match because of a shoulder injury and described her chances of being fit to play Jelena Jankovic in the next round as "50-50".

"I tried to forget the pain, but it was really hard," world number 41 Bartoli told reporters.

"I will see how it goes in the warmup but I will not take any risks before the (January 17-30) Australian Open."

Top seed Amy Frazier of the U.S. beat the Czech Republic's Lucie Safarova 6-3, 6-1 and Serbia's second seed Jankovic overpowered Spain's Nuria Llagostera Vives 7-5, 6-2.

Japan's fourth seed Shinobu Asagoe went through after Shenay Perry of the U.S. retired. Asagoe had won the first set 6-1.
