Following the somewhat disappointing first round exits in the Australian for the British players, these are the current rankings:
Elena Baltacha 57 from 54
Anne Keothavong 88 from 73
Heather Watson 106 from 105
Laura Robson 118 from 134
Laura Robson's rise was due to her being the only one of the above 4 to have to go through the qualifying matches where she won all three matches and so gets a boost in the ratings.
