Madison Keys’ Grand Slam window wasn’t just closing. It had been slammed shut. She has always been an excellent player, but it felt like women’s tennis had passed her by. Far from her peak in 2017, when she was ranked No.

Madison Keys of the United States has upset two-time defending champion Aryna Sabalenka of Belarus 6-3, 2-6, 7-5 in the Australian Open final.

MELBOURNE, Australia — Jannik Sinner beat Alexander Zverev 6-3, 7-6 (4), 6-3 in the Australian Open final at Melbourne Park Sunday. The No. 1 seed prevailed over the No. 2 seed in a match ultimately decided by Zverev’s discomfort when coming forward, Sinner’s underrated first serve, and a kiss of death from the net.

World No. 2 Alexander Zverev was forced to address previous domestic abuse allegations made against him after he was heckled by a member of the crowd after the Australian Open final on Sunday.

Of all the praise bestowed on Jannik Sinner after he won his second consecutive Australian Open championship, and third Grand Slam title overall, nothing felt as significant as the comparison made by runner-up Alexander Zverev.
