Garbine Muguruza continued her dream debut at the WTA Finals by completing round- robin play with a perfect 3-0 record to advance to the semifinals after a hard-fought 6-4. 4-6 ,7-5 victory over Petra Kvitova on Friday.
By topping the White Group, the Spaniard set up a showdown against Poland's Agnieszka Radwanska while Kvitova (1-2) received a huge boost from her Czech Fed Cup teammate Lucie Safarova (1-2), who beat Angelique Kerber to help her advance.
Germany's Kerber (1-2) only needed to win a set in Friday's second match to move on but the already-eliminated Safarova (1-2) found her best form of the week to blast the German off the court and out of the eight-woman event with a 6-4, 6-3 win.
