Wozniacki spent a total of 67 weeks as the word No. 1 but never was able to capture a Grand Slam title. Still one of the most popular players on tour, the Dane has fallen to No. 51 in the world and hasnt won consecutive matches since June. Wozniacki has reached two US Open semifinals and two finals in her career; two years ago, she lost to Serena Williams in the championship match. Townsend, one of the brightest American juniors in recent years, has yet to make a mark on the WTA Tour. Two years ago, she made the third round of the French Open, but in five other Grand Slam appearances, has won only a single match.No. 5 Rafael Nadal versus Denis Istomin, third match on Arthur Ashe Stadium (Watch)What to make of Nadal? He looked incredible in his first two matches at Roland Garros before abruptly pulling out with a wrist injury. After missing two months (including Wimbledon), Nadal returned to action in Rio and reached the semifinals -- admittedly surprising even himself. Only an unforgettable three-set loss to Juan Martin del Potro in the semifinals kept Nadal from a shot at his second gold medal. The Spaniard, though, won the doubles title with partner Marc Lopez. Nadal says hes in good spirits and healthy entering New York. Hes never lost a match to Istomin in four previous encounters.No. 26 Jack Sock versus Taylor Fritz, 5:30 p.m. ET on Louis Armstrong Stadium (Watch)Certainly, one of the main attractions on opening day, this battle will feature two of the most talented Americans in the field. Sock, the newly minted mix-doubles Olympic champ, hopes his home Slam will snap him out of a singles funk. The 26th seed hasnt won more than two consecutive matches since the Clay-Court Championships back in early April. Fritz, 18 and perhaps the most talented of the new wave of U.S. mens players, reached the Memphis Open final six months ago, but since then has struggled, notably going only 3-7 in his past 10 matches.No. 1 Novak Djokovic versus Jerzy Janowicz, 7 p.m. ET on Arthur Ashe Stadium (Watch)Fittingly, the world No. 1 will begin his quest to defend his US Open crown under the lights in Arthur Ashe Stadium. With a title, Djokovic would join Roger Federer as the only players to win three majors in the same year on three occasions. The Serb, however, enters New York with a cloud of uncertainty. He fell early at Wimbledon, and after winning the Rogers Cup Masters, lost to del Potro in the opening round of Rio. Djokovic is also dealing with a wrist issue that he said still isnt 100 percent. Like del Potro, Janowicz possesses a thunderous game. A 2013 Wimbledon semifinalist, Janowicz (once ranked No. 14) has fallen to No. 228 in the world and has played only two matches this season.No. 8 Madison Keys versus Alison Riske, second night match on Arthur Ashe Stadium (Watch)In another all-American battle on opening day, the biggest question mark will be the health of Keys, who just last week withdrew from the Connecticut Open after injuring her neck during a practice session. But Keys has played well lately, winning 25 of her past 31 matches. This includes a trip to the Montreal final and the Rio semis. Shes also made the fourth round or better in every major dating back to last years US Open. Keys won a title on the grass of Birmingham right before Wimbledon. As for Riske, she is sporting a healthy 29-19 record this season, and just a few weeks ago reached the semifinals in Stanford. San Antonio Spurs Shirts .
