In her very first US Open main draw, Canadian tennis sensation Bianca Andreescu booked her ticket to the semi-finals on Wednesday night.

It wasn’t easy, but the 19-year-old was able to take the quarterfinal matchup 3-6, 6-2, 6-3 against Belgium’s Elise Mertens.

The first set proved to be the most difficult for the rising star, who made a number of mistakes that Mertens was able to capitalize on. However, the Rogers Cup winner didn’t let that shake her.

In 2019, Andreescu has had a history of starting off slow and finishing high – Wednesday night was no different. So, the Mississauga native went into the next set ready to do what she does best: turn things around.
