Jamie Murray and Martina Hingis add US Open mixed doubles glory to Wimbledon title as their partnership flourishes again

Since teaming up at Wimbledon, Jamie Murray and Martina Hingis have quickly established themselves as the nearest thing to an unbeatable partnership you are likely to see.

Doubles tennis is an unpredictable form of the game, especially with “no-ad” scoring (in which only one deuce can be played per game). Yet Murray and Hingis have now won both tournaments they have entered together,  extending their 100 per cent record into a tenth successive match yesterday to land the US Open title.

Their latest victims – Michael Venus and Hao-Ching Chan – formed an  unlikely geographical partnership  between New Zealand and Chinese Taipei. The underdogs put up stubborn opposition, fighting back from a 6-1 beating in the opening set to take the contest to a tie-break after winning the second set 6-4.

But it was Hingis’ class that made the difference, as she hit two backhands up the line on match point, setting up Murray for the winning volley.

After splitting just £100,000 with Hingis for their Wimbledon feats,  Murray expressed dissatisfaction at the size of their reward. “Mixed doubles cheque is same as 2007,” he wrote on his Twitter page. “So it’s actually less valuable than ten years ago.”

Here the figures are slightly better, thanks to the relative strength of the dollar, and Murray can expect to take home around £57,000 before tax, plus perhaps £32,000 from his run to the quarter-finals of the men’s doubles.

The real prize, though, is Hingis – whose status as the best doubles player in the game is underlined by her  presence in today’s women’s final, alongside partner Yung-Jan Chan (who is Hao-Ching’s sister).

At the trophy presentation, Hingis was asked if she planned to stick with this partnership, and her reply was worryingly non-committal. “I’m just glad to have survived today,” she said.
