Sloane Stephens was planning to spend Saturday night in New York celebrating with Madison Keys, hours after beating her friend to a first Grand Slam title.
The 24-year-old American, ranked 83rd until Monday, thrashed 15th seed Keys 6-3 6-0 in just 61 minutes to complete a scarcely believable return from injury.
Asked if she would be buying the drinks, Stephens confirmed: "Yes, a lot of them apparently. We are having a little celebration and she is coming."
Just 69 days after returning from an 11-month injury lay-off, and six weeks since her ranking dropped to 957, Stephens became only the fifth unseeded woman to win a Grand Slam singles title in the Open era.
