He saved four match points against American former world number eight Isner.

Wu is set to rise to world number 58 when the rankings are updated on Monday, making him the highest-ranked Chinese player in ATP history.

Playing in his maiden Tour-level final, he did not compete on the Tour from March 2019 to January 2022 because of numerous injuries.

But he defeated American top seed Taylor Fritz and Canada's third seed Denis Shapovalov en route to the final.

Murray and Venus are experienced doubles campaigners

Jamie Murray and new partner Michael Venus of New Zealand claimed their first men's doubles title together after linking up last month.

The pair, top seeds in Dallas, defeated Americans Nathaniel Lammons and Jackson Withrow 1-6 7-6 (7-4) 10-7.

"We had a great week. We had to battle a lot," said Murray, who has now won a Tour title in 11 consecutive seasons and Venus nine.

"We went down really hard in the first set, but we stayed calm and kind of committed to what we were trying to do out there and worked our way into the match. We are super happy with how it turned out."
