U.S. Open champion Bianca Andreescu has discovered a powerful tool to compensate for limited training opportunities amid the COVID-19 lockdown as the Canadian teenager remains focused on her goal to climb to the top of the women's rankings.
Andreescu, currently ranked sixth in the world, won her first WTA title at Indian Wells last year and then beat Serena Williams in the finals at Toronto and again at the U.S. Open in Flushing Meadows to clinch her first Grand Slam crown.
But her climb up the rankings was halted after she injured her left knee at the WTA Finals last October.
