Tuesday night, Sebastian Korda resigned from their Australian Open match in the third set due to a right wrist injury, advancing Karen Khachanov to his second consecutive Grand Slam semifinal.
The 18th seed was in the lead 7-6(5), 6-3, and 3-0 after winning seven straight games after the American's medical stoppage in the middle of set two. After failing to serve out the set at 5-3, Khachanov recovered with a powerful tie-break to take the opening set with a brave backhand winner. Then, early in the second, as he continued to dominate with his reliable baseline game, he watched three break points go to waste.
At 3-2 in the second set, Korda requested a medical timeout and had his wrist wrapped; nonetheless, after he resumed play in Rod Laver Arena, Khachanov rapidly widened his advantage as Korda struggled to control his forehand. The American's retirement marked the first one in men's singles draw at this year’s competition.
