Facing Sinner reminded Alexander Zverev of trying to solve the challenge presented by the 24-time major champion Djokovic.

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.

Jannik Sinner, a 23-year-old Italian, is the youngest man to leave Melbourne Park with the trophy two years in a row since Jim Courier in 1992-93.
