KEYS TO BEAT SVITOLINA @ EVENS
Svitolina has not played to her full potential so far this week after a great season and Keys has the power to hit through her. Keys can be erratic but if she is on form then her powerful serve and groundstrokes will be very difficult for Svitolina to cope with as was shown in their only meeting when Svitolina retired 4-2 down in the second set after losing the first set.
SAFAROVA TO BEAT VANDERWEGHE @ 11-10
Safarova leads the head to head 3-1 and on hard court she leads 2-0. Coco has not looked overly impressive in reaching this stage coming through in three sets against Riske and also Radwanska when in all honesty she should have lost. Safarova has also been taken to three sets twice but actually ended up winning those matches quite easily and I cannot get away from the head to head which I think shows Vanderweghe does not enjoy this match up.
