Catherine Bellis aka Cici, exudes energy indeed; the 17-year old dynamo born in the good, ole US of A, swung her way to her third round match at the US OPEN this past September in front of a roaring crowd. The red, white and blue home- grown fans gave Bellis a warm welcome when she entered the match. As the youngest player ranked in the WTA top 100 at the end of 2016, she is revving up for the new year and already has one singles title on the WTA tour and six singles and two doubles titles on the ITF tour in her career. This American Nextgen player is even up on the hottest trends off the court, including a video with her friends taking the mannequin challenge decked out in their tennis gear on the court. A-mazing! You must check it out. Bellis is definitely one to watch in the singles rounds, and she continues to pursue her climb in the rankings in the doubles matches as well. Way to go!
