Ben Shelton has reached his first Australian Open semifinal by defeating Lorenzo Sonego 6-4, 7-5, 4-6, 7-6 in an entertaining match.

Defending champion Jannik Sinner overcame an early test against American Ben Shelton to reach his second straight Australian Open final, winning 7-6 (2), 6-2, 6-2.

The win sets up a showdown with Alexander Zverev of Germany in Sunday’s final. Earlier Friday, Zverev won the first set of his semifinal when Novak Djokovic missed a putaway volley in a tiebreak. Djokovic retired on the spot, unable to overcome the muscle tear he suffered in his quarterfinal win over Carlos Alcaraz Tuesday night.
