2016 US Open: Top 5 dark horses for the Women's Singles tournament

#1. Madison Keys

The ninth seeded American has been in really good form this year and will be looking to have a memorable outing at the US Open

The eighth-seeded American will probably be the biggest dark horse heading into the US Open. After an injury-affected Australian Open, Keys put up a series of strong performances in the clay court season which included reaching the final of the Italian Open and a personal best fourth appearance at the French Open.

She continued her good form in the grass court season as well, winning the Aegon Classic which helped her enter the Top 10 for the first time in her career. After a fourth round outing at Wimbledon, Keys reached the final of the Rogers Cup before reaching the semi-finals of the Rio Olympics.The offensive baseliner will be starting off her US Open campaign against compatriot Riske and will be expected to have a smooth journey till the fourth round where she would be up against the 2004 US Open Champion Svetlana Kuznetsova.

If she betters her fourth round performance of last year, then she would lock horns with French Open winner Garbine Muguruza in the final eight. Keys has been one of the most promising players this year and if she maintains her consistent performances, then she could well be a tough player to beat.
