US Open 2016: 5 unseeded players who have stood out so far

#2 Caroline Wozniacki

The Former World No.1 will be a player to look out for in the quarter-finals

On April 20th, 2009 a 23-year old Russian, Dinara Safina was ranked the new World No.1 and was only the second player to rank No.1 without winning a Grand Slam.

Caroline Wozniacki is another player who was World No.1 for quite some time but hadn’t won a Grand Slam title. She too had a dip in form but came back strong in 2014 before going through another decline in 2015.

Prior to the US Open, Wozniacki was ranked 51st in the world and was not expected to clear the second round as she would be up against a resurging Svetlana Kuznetsova. After surviving a scare from qualifier Taylor Townsend in the opening round, Wozniacki stunned 2004 Champion Kuznetsova in straight sets to reach the third round of a Grand Slam for the first time since last year’s Wimbledon.

After beating Romanian Monica Niculescu in the third round, Wozniacki will now face a resilient Madison Keys, who was coming at the back of a splendid comeback against Japan's Naomi Osaka.

Wozniacki scripted another major upset (in terms of rankings) by beating Keys in straight sets.
