SINGAPORE — Spain's Garbine Muguruza moved to the brink of the WTA Finals last four with a 6-4 6-4 win over Angelique Kerber on Wednesday after Petra Kvitova opened her account with a 7-5 7-5 victory over fellow Czech Lucie Safarova.
Muguruza (2-0) came into the tournament on the back of her first premier level tournament win in Beijing at the start of the month and backed up her impressive opening round-robin win over Safarova with another straight sets victory over Kerber.
Kvitova (1-1), Kerber (1-1) and Safarova (0-2) can all still advance to the last four from the 'White Group' with one round of matches to play but Muguruza is in prime position to advance as the winner of the four-player pool in Singapore.
