Zverev halts Tien to reach fourth Melbourne semifinal

Alexander Zverev defeated Learner Tien 6–3, 6–7(5), 6–1, 7–6(3) to reach his fourth Australian Open semifinal. The German also advanced to his tenth major semifinal, ending the twenty-year-old American’s best Grand Slam campaign after three hours and thirteen minutes.

Zverev produced fifty-six winners, including twenty-four aces, and praised Tien’s exceptional baseline play. After losing a sixty-six-minute second set, he regained control in the third without committing an unforced error, while Tien failed to win a point behind second serve.

Tien still created a set point in the fourth, but Zverev saved it with a powerful serve and controlled the closing tiebreak. The result preserved the third seed’s strong record against left-handers and set up a semifinal against Carlos Alcaraz or Alex de Minaur.
