28 players split into 4 groups of 7, top 2 (and ties) from each will go into the final.
As always, vote for the person/players you feel is the player of the month from the list below - if you can say when you vote and for who and why, that always helps!
Vote will close at 8.50 am Tuesday morning, final to be posted shortly thereafter

I voted for Olivia. I'm so happy see her winning on the Tour again. I really hope she can find a regular partner to complement her talents as I feel sure there is a lot more to come from her.
Oof, this is a tough group to decide! I'm going for the Great Britain 12U girls team, as that's a fantastic team effort from young players, but could have happily voted for anyone in this group.
