Korda claims another upset at AO

Giantkiller Sebastian Korda said that learning from his mistakes helped him surge into a maiden Grand Slam quarter- final on Sunday at the Australian Open (AO). The American 29th seed came through a rollercoaster 10-point deciding tiebreak to beat 10th seed Hubert Hurkacz 3-6, 6-3, 6-2, 1-6, 7-6 (10/7) on Rod Laver Arena. He faces 18th-seeded Karen Khachanov next after the Russian crushed Yoshihito Nishioka 6-0, 6-0, 7-6 (7/4), incredibly winning the first 14 games before the Japanese player woke up.
