Taiwan's Chan Hao-ching and Michael Venus on Saturday failed to claim the mixed doubles title at the US Open despite rallying to win the second set against top seeds Martina Hingis and Jamie Murray, while top seeds Hsu Yu-hsiou of Taiwan and Wu Yibing of China claimed the junior boys' doubles title.
"Obviously, a lot of money has been pumped into the Grand Slams over the last few years and people are making a lot more money than they used to, but a majority of that is going into the singles game", said Murray, 31.
Martina Hingis and Jamie Murray have been the flawless partnership.
"She's an wonderful player, she's had such a great career", he said.
Seeking to become the first Kiwi to win a mixed doubles title at one of the year's four big tournaments, he lost a thriller in the final of the US Open in NY. In the five years since her return she has won 24 women's doubles titles, including three at Grand Slam level, enjoyed a spell on top of the world rankings and won six Grand Slam mixed doubles titles.
Murray and Hingis romped through the draw at Wimbledon but things were tougher here.
Hingis hinted she may retire for a third time but said if did turn out in 2018, she would "definitely" play with Murray.
Says Keys: "She can buy me drinks, all of the drinks".
And the 36-year-old - she turns 37 later this month - appeared to hint during the press conference that she is thinking about retiring for a third time.
"It's been a lot of fun, we've won a lot of close tennis".
Murray would also like to see more prize money put into mixed doubles. "I think that that should be supported".
Both are playing the best tennis of their careers after having surgery.
