Men's singles
James Duckworth leads Australia's ranking risers this week after capturing the Mexico City Open title in a three-set epic.
The 34-year-old bested Italian Stefano Napolitano 6(7)-7 7-6(3) 6-2, after the match was halted at 5-5 in the second set due to heavy rain.
It was Duckworth's 18th Challenger crown, moving him to equal fifth on the circuit's all-time titles leaderboard alongside Japan's Go Soeda.
The feat catapulted the Australian 16 places in the ATP rankings to world No.70, his highest ranking since October 2024.
It comes a week after Duckworth made the final of the San Luis Potosi Challenger, falling to Colombia's Nicolas Mejia, which improved his ranking by nine places.
Other risers included Adam Walton, Tristan Schoolkate, Dane Sweeny and Christopher O'Connell.
Outside the Aussie top 10, Li Tu increased 35 places after reaching the semifinals at the Wuning 1 Challenger.
