Eighteen-year-old Alex De Minaur (NSW) has been awarded a wildcard into the US Open.

The rising Aussie star has had a breakthrough season which has seen his ranking soar from world No.351 in January to a career-high of 186 this week. He reached his first ATP Challenger final in Spain last week and won his first professional title, an ITF Futures, in Portugal last month.

Third seed Stan Wawrinka of Switzerland outgunned World No.1 Novak Djokovic 6-7 (1-7), 6-4, 7-5, 6-3, to clinch his first US Open title at Flushing Meadows, New York on Sunday.

The 31-year-old Swiss continued to show that he is a man for the big occasion, winning his third Grand Slam title in as many major final appearances, after he won the Australian Open in 2014 and the French Open in 2015.

Felix Auger-Aliassime (Montreal) became just the fourth Canadian ever, and the youngest, to win a junior Grand Slam singles title on Sunday after defeating Serbia’s Miomir Kecmanovic 6-3, 6-0 at the US Open. This was the second attempt of the year for Auger-Aliassime who came up just short at the Junior French Open in June, finishing there as the runner-up.

Auger-Aliassime was dominant from the start, going up an early break in the first set to take a 4-1 lead. He never looked back, allowing his opponent to win only three games the entire match, which lasted just 58 minutes. He served incredibly well, winning 80 per cent of his first serve points and producing 22 winners versus seven for Kecmanovic. It was the perfect redemption match for Auger-Aliassime, who squandered three match points in the Junior French Open final before ultimately losing the match.

Southern Californian Kayla Day celebrated two milestone achievements on Sunday, Sept. 11, in New York City.

The 16-year-old Day, the No. 5-seed from Santa Barbara, defeated the No. 13-seed Viktoria Kuzmova of Slovakia, 6-3, 6-2, on the Grandstand Court at the USTA Billie Jean King Tennis Center to capture the US Open Junior girls singles title at the year’s final Grand Slam.

Germany's Angelique Kerber won the US Open Women's Singles final beating the Czech Republic's Karolina Pliskova 6-3, 4-6, 6-4 in a hard-fought and exciting match at Flushing Meadows.

Kerber, 28, won in New York on Saturday evening to claim her second Grand Slam title win after her triumph at the Australian Open in January. She had also finished runner-up to Serena Williams at Wimbledon.

Britain's Jamie Murray and Brazil's Bruno Soares bagged their first US Open Men's Doubles title, routing Spain's Pablo Carreno Busta and Guillermo Garcia Lopez 6-2, 6-3 in the summit clash.

The fourth seeds served and returned better to control the match from start to finish, striking 27 winners to the Spaniards' 17. They also committed just 11 unforced errors, 10 fewer than their opponents on Saturday.
