Sloane Stephens still in awe to the grand price of $3.7m after beating Madison Keys in US Open final

When a Roger Federer or a Serena Williams win a Grand Slam title the prize money is probably all but inconsequential, but Sloane Stephens’ eyes opened wide when she was presented with her cheque for $3.7m (£2.84m) after winning the US Open here on Saturday.

At her post-final press conference Stephens was asked if winning her first Grand Slam title would whet her appetite for more success. “Did you see the cheque that lady handed me?” Stephens said. “Man, if that doesn’t make you want to play tennis, I don’t know what will.”

Stephens, whose previous best run at a Grand Slam tournament had been when she reached the semi-finals of the 2013 Australian Open, said the size of the cheque had come as a surprise.

“The other day I saw a ticker going across the TV screen,” she said. “The prize money for the semi-finals was $900,000 and I literally almost passed out. I was like: ‘Oh my God!’ The last time I had played in a semi it was $500,000 or something like that. It was shocking.”

By beating Madison Keys 6-3, 6-0 Stephens almost doubled her career prize money. Asked if she felt bad about beating her close friend in the final, Stephens replied: “Bad for her? She was in the final, too. What do you mean? Did you see the cheque she’s about to get? I’m sure she’ll be just fine.”Stephens admitted that she has expensive tastes.

“Shoes, bags, cars, clothes, houses, anything,” she said. “My family also have their own expensive tastes, let me tell you. They’re on another level as well. I like nice things.”

She said the most extravagant purchase she had made was the house she bought two years ago. “People skimp on their houses,” Stephens said. “My house is like my sanctuary. It has to be really nice. I take pride in that.”

In world ranking terms, Stephens’ reward for her victory will be a rise from No 83 to No 17 in Monday’s updated list. Only six weeks ago she was ranked No 957 as she began her comeback after 10 months out of the game because of foot surgery.

The 24-year-old is the lowest ranked woman ever to win the title here, Kim Clijsters having been unranked when she triumphed in 2009 in only her third tournament since starting her comeback after a two-year break from the game. Since the launch of the rankings in 1975, the only lower ranked woman to reach any Grand Slam singles final was Chris O’Neil, who was world No 111 when she won the Australian Open in 1978.
