Friday's key matches
No. 9 Jo-Wilfried Tsonga vs. Kevin Anderson, first match on the Grandstand (Watch)
Expect nothing less than first-to-last ball power from both players in this one. The seeds suggest Tsonga is the favorite, but Anderson had his best Grand Slam showing last year at the US Open, where he reached the quarterfinals, a run that included a win against Andy Murray. Tsonga has not played well since Wimbledon. But after his last match, he said the small imperfections in his game have been fixed.
No. 7 Marin Cilic vs. No. 26 Jack Sock, second match on Louis Armstrong (Watch)
Cilic is perhaps the last player anyone wants to run into right now. The 2014 US Open champ thrives on the hard courts of New York. Plus, he's coming off an impressive title run at the Western & Southern Open two weeks ago. Cilic has been broken just twice in his first two matches at the US Open this year. As for Sock, after a thrilling five-set win against fellow American Taylor Fritz in his opener, he settled in nicely. On Wednesday, Sock dismantled Mischa Zverev in less than 90 minutes.
Ryan Harrison vs. Marcos Baghdatis, second match on Court 17 (Watch)
Once the front-runner to be the Next Big Thing in tennis, Harrison had fallen on hard times, toiling in the anonymity of Challenger events. But Wednesday, he scored the biggest victory of his career, a four-set win against No. 5 and Wimbledon runner-up Milos Raonic. Harrison entered the US Open ranked a lowly No. 120 and made the main field only by qualifying. He credits his mental maturity as one of the reasons for his rebound. His opponent, Baghdatis, is equally interesting. One of the most charismatic players on tour, the Cypriot was also one of the game's highly touted future stars; in 2006, he made the Australian Open final but hasn't delivered anything close to that performance since. Baghdatis beat Harrison in their only previous encounter, the 2012 Brisbane International.
No. 13 Johanna Konta vs. No. 24 Belinda Bencic, second match on the Grandstand (Watch)
No question Konta has to be worried about her physical state after a frightening incident Wednesday. Midway through her match on a hot, humid day, the Brit began to hyperventilate and ultimately collapsed to the ground, shaking and shivering. After a lengthy delay, Konta recovered and won. She is hopeful that with some "TLC, I'll be good to go." On Friday, she will face Bencic, who has had a dismal summer. In her previous five events, she won only a single match. However, Bencic is coming off an impressive win against Andrea Petkovic on Wednesday.
No. 20 John Isner vs. Kyle Edmund, fourth match on Louis Armstrong Stadium (Watch)
The big question for Isner won't be whether darts will be flying off his racket or his desire to thrill the New York crowd, but rather how his legs will hold up. In two matches, the 6-foot-10 American has been on court for 6 hours, 21 minutes over nine sets. He was lucky to get by Frances Tiafoe in his opener, and his second match, against Steve Darcis, was a physical struggle from the beginning. It won't get easier for Isner. His next opponent, Edmund, is responsible for taking out No. 13 Richard Gasquet on Monday. Isner beat Edmund in the second round of the French Open earlier this year.
No. 2 Angelique Kerber vs. CiCi Bellis, second night match on Arthur Ashe Stadium (Watch)
What a fairy-tale story it would be if 17-year-old Bellis could upset the No. 2 player in the world. Bellis loves the energy from the New York crowd. She has a growing legion of fans who call themselves "Team CiCi." It's not the first time the California teen has stolen the spotlight in New York; two years ago, she stunned former Aussie Open finalist Dominika Cibulkova in the first round. Kerber, of course, will be a much more difficult test. She won her major, in Melbourne, earlier this year and then reached the Wimbledon and Olympics finals.
