After being closed to fans last year, the tournament is the first Grand Slam since the coronavirus pandemic started to be allowed a 100% capacity throughout.
New York host the 2021 edition of the US Open at USTA’s famous Billie Jean King International Tennis Center from August 30 to September 12.
Highlights of the first day as it happened
OSAKA BATTLE PAST BOUZKOVA
Naomi Osaka plays a very positive match to start her title defense at the US OPEN .
Naomi Osaka had a solid start to the defense of her U.S. Open title, posting a 6-4, 6-1 win over Marie Bouzkova of the Czech Republic that was a little closer than the final score suggested.
Osaka was born in Japan and represents that nation but grew up largely in New York and Florida.
“It feels kind of amazing to play in front of everyone again,” Osaka said after the match, “The energy here is unmatched.”
HALEP SURVIVES GIORGI TEST
Former world number one Simona Halep overcame a tough opener against Italian Camila Giorgi.
Halep, a two-time Grand Slam tournament champion, had not won a match since May after tearing a left calf muscle during the Italian Open in Rome but battled past Camila Giorgi 6-4 7-6(3) to set-up a second-round meeting with Slovakia’s Kristina Kucova.
TSITSIPAS SURVIVES MURRAY SCARE
Third seed Stefanos Tsitsipas was pushed to five sets by 2012 champion Andy Murray before the Greek prevailed 2-6 7-6(7) 3-6 6-3 6-4 in a marathon clash in Arthur Ashe Stadium lasting nearly five hours.
Murray started the match well, and led in the second set tie-break before he lost his footing — and his lead — because his shoes were slippery. Though he won the third, Tsitsipas proved the better player down the stretch, though seemed to win few fans in the process.
KREJCIKOVA AIMING FOR ANOTHER SLAM
French Open champion Barbora Krejcikova handed Astra Sharma a bagel en route to victory on her main draw debut at Flushing Meadows, winning 6-0 6-4.
CILIC RETIRES WITH INJURY
Cilic retires for first time in more than 800 matches.
Marin Cilic, the 2014 champion, retired injured from his first-round match with Philipp Kohlschreiber with the contest locked at two sets each.
RUBLEV EASES PAST VETERAN KARLOVIC
Fifth seed Andrey Rublev of Russia brushed aside 42-year-old Ivo Karlovic 6-3 7-6(3) 6-3 to reach the second round.
Earlier, 11th seed Diego Schwartzman beat Ricardas Berankis 7-5 6-3 6-3 and 12th seed Felix Auger-Aliassime battled past Evgeny Donskoy 7-6(0) 3-6 7-6(1) 7-6(8) while Brandon Nakashima stunned 19th seed John Isner 7-6(7) 7-6(6) 6-3.
Fourth seed Alexander Zverev gets the action under way on Arthur Ashe against Sam Querrey, before women’s world number one Ashleigh Barty takes on Vera Zvonareva. Novak Djokovic then begins his bid for the calendar grand slam against Holger Rune.
