0302 OSAKA RALLIES TO VICTORY Naomi Osaka dropped the opening set before coming back to defeat Latvian Anastasija Sevastova 4-6 6-3 6-4 and reach the Australian Open quarter-finals for the first time.
After losing the first set tamely, Osaka earned a decisive break to go up 4-2 in the second set before levelling the match. The world number four endured some nervy moments in the decider before sealing the contest in one hour and 47 minutes. Up next for Osaka is WTA Finals champion Elina Svitolina. The Japanese has lost three of their five career meetings, including their most recent clash at Miami last year.
