Sonego defeats Tien, reaches first Australian Open quarter-final

Lorenzo Sonego has reached the quarter-finals of the Australian Open for the first time in his career by defeating 19-year-old American Learner Tien in four sets, 6-3, 6-2, 3-6, 6-1. Sonego, the last unseeded player remaining in the tournament, previously eliminated another teenager, Joao Fonseca, in the second round. Despite Tien's strong performance throughout the tournament, including a notable upset of Daniil Medvedev, he struggled physically against Sonego, who dominated with his powerful serve and a total of 58 winners. Sonego expressed mixed emotions about the victory, acknowledging Tien's difficulties during the match but feeling ecstatic about his own advancement. The Italian's next opponent will be determined from the match between Gael Monfils and Ben Shelton. The atmosphere at John Cain Arena was described as special, adding to the significance of Sonego's achievement.
