Heather Watson's Australian Open run came to an end with a straight-sets defeat by Polish fourth seed Agnieszka Radwanska.
After a strong start, the British number one went down 6-3 6-1 in 84 minutes on Hisense Arena.
The classy Radwanska outmanoeuvred Watson in a match that ended under the roof because of rain, and she will face former French Open champion Ana Ivanovic in round four.
Laura Robson's match against Sloane Stephens tomorrow will be a good test to see how far Laura Robson has progressed to date in her career as Sloane Stephens (ranked 25) is the closest to Laura in age in the top 50. (Heather Watson is slightly older than both). Sloane Stephens has to be a strong contender for getting to the top of the rankings over the next 2 to 3 years.
