Why couldn't Donna get Brooke Austin who plays vs Lisjak.
Not such a bad draw however I believe SIrotkina is favorite, she just ost to other Pliskova in Bronx 67 in final set and before that played finale of 100K in Astana.
Also she has experience in GS qualies already.
Reached FQR in Wimbledon where she lost to Czink.
Good luck Donna!
