PAW17 Anderson over Berdych
PAW18 Almagro over Tipsarevic
Paw19 Ferrer over Nishikori
These are your PAW's 19, 20 and 21.
I have to say that the PAW numbering in this tournament has been generally quite poor. I am trying to keep the Pick Summary (Post #6) as up to date as possible but maybe some players need to be reminded to check the Pick Summary before posting picks.
