Coco Guaff clinches her first WTA finals trophy

America's tennis player, Coco Guaff defeated Zheng Qinwen of China 3-6, 6-4, 7-6(2) to clinch the WTA Finals trophy, which is her first year-ending championship title of her career.

Coco Guaff came into the competition with mixed feelings as she had failed to reach the expectations of her supporters in every Grand Slam that she had participated in throughout this season. She is the first American to win the WTA trophy since Serena Williams in 2014.

She had to come back from a breakdown in the second set, and she was twice down a break in the third set, where Zheng served for the match at 5-4. But, Gauff fought back on each of those occasions to win her ninth career WTA Tour singles title.

Gauff becomes just the second American since 1990 to claim four Top 10 wins at a single event before turning 21. Lindsay Davenport first achieved that feat en route to the gold medal at the 1996 Olympics,

The American ended the season as World No.3 ranking for the second straight year. She was also rewarded with 4,805,000 dollars for emerging victorious which is the largest payout at a WTA Tour event.
