BETTING GUIDE

Williams, despite her past success in New York, is the underdog in her match Tuesday, according to FanDuel Sportsbook. Minnen is the minus-156 favorite, while Williams is listed at plus-130. Alcaraz is minus-7000 in his opener but Djokovic remains the U.S. Open favorite at plus-110. Alcaraz is at plus-185 and Medvedev at plus-1,000. For the women, Swiatek became a stronger choice at plus-210, followed by Aryna Sabalenka, who won the Australian Open title in January, at plus-500.

JACK SOCK’S SWAN SONG

Jack Sock, a four-time Grand Slam doubles champion who was on the winning side in Roger Federer’s final match, will join John Isner in retirement after they team up in U.S. Open doubles. Sock, who also won two Olympic medals in doubles in 2016, revealed his retirement plans in an Instagram post on the eve of the tournament. He and Isner were given a wild card in the men’s doubles draw. Isner announced he was retiring last week. Sock and Frances Tiafoe edged Federer and Rafael Nadal last year at the Laver Cup after Federer had said it would be his final match before ending his career.

WHO’S NO. 1?

Djokovic will be in the next rankings on Sept. 11. He came to New York 20 points behind Alcaraz but guaranteed his return to the top by winning his opening match. That’s because since he couldn’t play at the U.S. Open last year, Djokovic has no points to defend in the rankings system. The 36-year-old from Serbia has already held the No. 1 ranking for 389 weeks, a record in men’s or women’s tennis. Swiatek is the women’s No. 1 and her stay at the top of the WTA rankings will reach 75 consecutive weeks, but Sabalenka will surpass her if she goes one round further in Flushing Meadows.
