The upsets continued on Day 3 of the 2013 Cairns Tennis International as defending champion and number four seed from South Australia Luke Saville succumbed to fellow statesman Darren Polkinghorne.

In what would be his biggest career scalp so far, Polkinghorne held his nerve to defeat Saville 6-3 4-6 6-3.

Another enthralling encounter followed on centre court as fifth seeded Sally Peers from Victoria was made work hard for her 7-6(7) 3-6 6-2 win over Queenslander Olivia Tjandramulia.

Peers was joined in the quarterfinals by 15-year-old Queenslander Priscilla Hon; Hon dominated from start to finish against Romanian sixth seed Daiana Negreanu, running out a 6-0 6-3 victor.

Number three seed Adam Feeney from New South Wales continued his march towards his second straight Pro Tour title by outclassing Queenslander Oliver Anderson 6-3 6-4.

Other winners on Thursday included Andrew Whittington, Jordan Thompson, Maverick Banes, Azra Hadzic, Kimberly Birrell and top-seeded Slovakian Zuzana Zlochova.
