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.

Current UCLA freshmen Jada Hart and Ena Shibahara survived two match points, capturing the US Open Girls title in dramatic fashion Saturday night at the USTA Billie Jean King National Tennis Center in Flushing Meadows, N.Y.

Given a wild card into the tournament by the USTA, Southern Californian’s Hart, from Colton, and Shibahara, from Rancho Palos Verdes, came back to defeat the American team of Kayla Day (Santa Barbara) and Caroline Dolehide (Hinsdale, Ill.) on the Grandstand Court, 4-6, 6-2, 13-11. It was the first time since 1992 that there was an all-American girls’ doubles final.

Canada went 1-1 in singles at the Junior US Open on Saturday, as Felix Auger-Aliassime (Montreal) is now one win away from clinching his first Grand Slam singles title thanks to a semifinal triumph, while Bianca Andreescu (Mississauga, Ont.) was unable to join him with a three-set loss in the girls’ draw.

Auger-Aliassime took on junior world No. 1 Stefanos Tsitsipas of Greece and ousted the 18-year-old 6-4, 7-5. In the match, which lasted one hour and 45 minutes on another stifling day in New York, No. 6 seed Auger-Aliassime blasted nine aces and 32 winners, and saved three of the five break points he faced.
