Day 7 Recap
• Defending champion Marin Cilic, Jo-Wilfried Tsonga, and a resurgent Venus Williams advanced to the quarterfinals.
• Top seeds Novak Djokovic and Serena Williams both advanced to the quarterfinals. Williams was pushed to three sets in the previous round by Bethanie Mattek-Sands but was able to advance in straight sets against Madison Keys, a much stronger player than Mattek-Sands. All eyes are on Serena as she attempts to become just the fourth women’s player in history to win a calendar-year Grand Slam. For some, her match against Mattek-Sands was a sign of her feeling nerves and pressure. She returned to form on Day 7. Djokovic advanced in straight sets.
• In one of the day’s only upsets, the unseeded Kristina Mladenovic defeated 13th seed Ekaterina Makarova in three sets. Mladenovic will take on Roberta Vinci in the quarterfinals.
• This Open has seen a remarkable amount of retirements and withdrawals from matches due to cramping and strange injuries. Perhaps no injury is stranger than the unexpected concussion that 25th seed and fan favorite Eugenie Bouchard suffered earlier in the week. She initially withdrew from her doubles and mixed doubles matches, but was also unable to play her singles match against Roberta Vinci yesterday. This result is one in a string of disappointments for Bouchard who, after a breakout 2014 season, has had an inconsistent 2015.
Day 8 Marquee Matches
Donald Young vs. Stan Wawrinka (5)
Young, a former junior world No. 1 player, has had a lackluster pro career but has surprised at this Open. Playing two five-set matches and one four setter, he has defeated 11th seed Gilles Simon and, in the last round, 22nd seed Victor Troicki. In Stan Wawrinka he will have his most difficult match yet. Two-time Grand Slam champion Wawrinka has cruised, winning every match in straight sets. Young will need some of his magic from previous rounds if he is to contend with Wawrinka for a spot in the quarterfinals.
Prediction: Wawrinka in five
John Isner (13) vs. Roger Federer (2)
Isner will look to match his best U.S. Open result, a quarterfinal showing in 2011. After a strong summer in which he finished 3rd in the U.S. Open Series, Isner will be confident against Federer. His big serve could trouble Federer, and an American has the advantage of the New York crowd.
Prediction: Isner to upset Federer in five
Sabine Lisicki (24) vs. Simona Halep (2)
This matchup of former Grand Slam finalists is sure to provide compelling tennis. Since reaching the 2013 Wimbledon final, Lisicki has had mixed results including an up-and-down 2015. She has powerful groundstrokes and the game to compete with the top players. She will have an opportunity to do so against an in-form Simona Halep, who has won all of her matches at the Open in straight sets. As the second seed she has had a strong year, winning Indian Wells and reaching the finals of Toronto and Cincinnati. Halep is the more experienced and confident of the two, but Lisicki is dangerous when her tennis and mental game are in sync.
Prediction: Halep in three sets
