A wildcard for the women's singles event, the 17-year-old lost her second-straight match on Wednesday when she went down to Gabriella Da Silva-Fick 6-3, 6-1 in their Group B clash.

The final scoreline didn't reflect how competitive Rothman was against the 566th ranked in the world.

The teenager fought hard on every point and made life difficult for Da Silva-Fick, who has much more experience at the professional level.

Rothman will get more valuable experience on Thursday when she takes on arguably the favourite to win the women's event - Belinda Woolcock.

Woolcock, a former Bendigo International finalist, dominated her first two matches this week.

She's expected to make it three-straight wins against Rothman, but if this week is anything to by the Maryborough teen won't go down without a fight.

In other women's singles highlights on day three, number one-ranked Pranjala Yadlapalli cruised to a 6-1, 6-1 win over Jessica Fowler in their Group A clash.

In the other Group A match, Roisin Gilheany upset the previously undefeated Monique Barry 7-6, 6-2 to leave Yadlapalli as an unbackable favourite to advance from the group.

Jasmine Adams is on top of Group C after scoring her third win of the tournament.

For the second day in a row she needed three sets to win. This time she edged out Elena Micic 6-1, 4-6, 6-4.

Alisaon Bai kept her finals hopes alive by defeating Cydney Crunbie 6-4, 6-1.

Group D is a battle between the unbeaten Katherine Westbury and Alana Parnaby.

Both won their respective matches in straight sets on Wednesday and their clash in Friday's final round will determine the group winner.

The highlight of the men's matches on Wednesday was Brydan Klein's hard-fought 6-3, 4-6, 6-1 win over Matthew Romios in Group B.

Group A leader Marc Polmans didn't drop a game in his demolition of Brandon Laubser, while Enzo Aguiard broke through for his first win of the week against Ken Cavrak 6-0, 6-4.

In Group C, Calum Puttergil and Thomas Fancutt are undefeated after three rounds. If Puttergill can defeat Jeremy Beale on Thursday the group will be decided on Friday when Fancutt and Puttergil meet.

Li Tu and Omar Jasika look like battling for the top seed in Group D.
