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.

A year after earning his first Grand Slam title at the same event, Sinner became the youngest man to leave Melbourne Park with the trophy two years in a row since Jim Courier in 1993.
