Jack Draper won the battle of the British No 1s as he and playing partner Jessica Pegula beat Emma Raducanu and Carlos Alcaraz in the first round of the US Open’s revamped, star-studded mixed doubles competition.

Draper and Pegula then went on to beat Daniil Medvedev and Mirra Andreeva in the quarter-finals to advance to Wednesday night’s semi-finals in New York, where they will play Iga Swiatek and Casper Ruud.

Offering a $1m prize to the winners, a shorter set format and being played across two days ahead of the start of the main singles draw from Sunday, the new-look event has attracted a host of the world’s top-ranked players, with Tuesday’s action seeing the first round and quarter-finals take place.

Draper and Pegula are the event’s No 1 seeds thanks to their respective fifth and fourth-placed rankings on the ATP and WTA Tours and delivered an impressive display at Arthur Ashe Stadium to beat former US Open champions Raducanu and Alcaraz 4-2 4-2.

The pair immediately broke Alcaraz’s serve in the first game of the match to gain an early advantage, with the rest of the set going to serve.

Pegula and Draper then claimed a decisive second break of the Spaniard’s serve in the third game of the second set.

Speaking in his on-court interview after the match, Draper said: “I have got a pretty good partner!

“What an experience out here playing with Jessica against Emma and Carlos.

“It doesn’t get any better than this, so it’s just a pleasure to be out here playing against them and with such a great player.”

The semi-finals and final take place on Wednesday evening New York time, which is into the early hours of Thursday morning for UK viewers on Sky Sports.
