Four-time Grand Slam singles winner Naomi Osaka has started 2025 in style, beating Julia Grabher 7-5, 6-3 Wednesday to reach the quarterfinals of the Auckland tennis classic. Osaka overcame a swirling breeze and a lengthy rain break to progress comfortably beyond the second round. Although the wind often affected her ball toss, Osaka didn't drop her serve at any stage and broke Grabher once in each set to win her way to the Auckland quarterfinals for the second time.
