Men's singles
John Millman's semifinal run at the Delray Beach Open sees the Australian return to the world's top 80 in the latest ATP Tour men's singles rankings.
The Queenslander, who stunned Grigor Dimitrov on his way to a first ATP-level semifinal since October 2020, moved 11 places last week.
Aleksandar Vukic was equally impressive as he climbed to a career-high world No.118 following victory at the ATP Challenger in Bengalaru, India.
It was a maiden Challenger title for the 25-year-old Vukic, who also progressed to the quarterfinals of Adelaide and upset No.30 seed Lloyd Harris at the Australian Open earlier this year.
Max Purcell, a quarterfinalist in Bengalaru, climbed seven spots to world No.169.
Also sitting at a new career high, the 23-year-old Purcell edges Alex Bolt in the Australian men's top-10.
