Women's seeds tumble at Open as Medvedev faces Kyrgios test
Third seed Muguruza and sixth seed Anett Kontaveit both suffered second-round upsets in straight sets, opening up the bottom half of the women's draw.
The Ukrainian fourth seed bided her time and struck at key moments in the match in a display that bodes well for her chances at the French Open later this month.
