U.S. Open; Osaka Avoids Upset, Gauff Rallies

NEW YORK (AP) – There were moments on Tuesday when Naomi Osaka looked nothing like a No. 1 seed or a defending U.S. Open women’s singles champion. She fell behind 3-0 and wasted a match point in the second set while displaying questionable body language.  But Osaka eventually found her rhythm and completed a 6-4, 6-7, 6-2 victory over Anna Blinkova despite finishing with 50 unforced errors, more than double Blinkova’s total of 22 in the opening-round match.  American Sloane Stephens is out of the U.S. Open in the first round, just two years after winning the title. The No. 11 seed was stunned, 6-3, 6-4 by the 127th-ranked Anna Kalinskaya.  Coco Gauff has won her U.S. Open debut with a comeback effort against Anastasia Potopova. The 15-year-old Gauff lost the first set and was down a break before posting a 3-6, 6-2, 6-4 victory.  Gauff got a wild-card entry from the U.S. Tennis Association after making a surprising run to the fourth round at Wimbledon last month, her first Grand Slam event.  Gauff and Osaka are joined in the second round by fourth seed Simona Halep, who also needed three sets before posting a 6-3, 3-6, 6-2 victory over American Nicole Gibbs. Halep had dropped her previous U.S. Open matches, falling to Maria Sharapova and Kaia Kanepi.  Sixth seed Petra Kvitova and No. 7 Kiki Bertens dropped just six games apiece in breezing into the second round.  Men’s second seed Rafael Nadal remains unbeaten in opening-round matches at Flushing Meadows following a 6-3, 6-2, 6-2 win against Australian John Millman. Nadal had little trouble against the player who knocked out Roger Federer in the fourth round last year.  There were a trio of top-10 upsets on the men’s side as fourth seed Dominic Thiem (teem) was dispatched by Thomas Fabbiano in four sets. Eighth seed Stefanos Tsitsipas was beaten in five sets by Andrey Rublev and No. 10 Roberto Bautista-Agut  dropped a five-setter to Mikhail Kukushkin.
