Kyrgios retires hurt in major comeback blow

The 29-year-old Canberran, who held a set point in the first set tiebreaker, was frustrated upon leaving the court.

It follows Kyrgios' first-round exit at January's Australian Open, later admitting he had likely played his last singles match at Melbourne Park. 

It was Kyrgios' first appearance at a major since making the 2022 US Open quarter-finals and then requiring wrist and knee surgeries.
