Australian women's involvement at the China Open is down to just one singles player after Kimberly Birrell and Storm Hunter were both second-round casualties.
World No.41 Birrell suffered a 6-4 6-4 loss to Czech Marie Bouzkova at the WTA 1000 event in Beijing on Saturday night.
Birrell, 28, who won the Korea Open last Sunday with a win over compatriot Maya Joint in the final, raced out to a 3-1 first-set lead before dropping serve twice to lose it in 42 minutes.
