Bianca Andreescu could well make her way to an open title in the United States

Canada's Bianca Andreescu, 19, does not walk the field as much as she stammers. She does not just shout, "Come on!" And pulls her fist when she wins a big point; she will look directly at her opponent while she does it. She will throw her racket when she loses a point and will eagerly crush the ball when she wins a point. His body language is not as positive or negative as a show of incessant force. To look at her is to be convinced beyond doubt that she is entitled to all the points she earns and all the points she loses. As a long-time tennis writer, Ben Rothenberg Put the on Twitter, she "behaves more like an alpha than any WTA player I've seen on the scene for a while." And his game confirms it: More than five singles matches at this year's US Open, Andreescu has recorded 157 winners, 26 more than Serena Williams, semifinalist in power, that she could very well face in final. During the season, she went 7-0 against the top 10 players. She became the youngest woman to win the Indian Wells title since Serena Williams in 1999. In March, she twice beat Grand Slam winner Angelique Kerber twice in a week. Although she has had a good part of the summer to recover from a shoulder operation, she has 43-4 this year and continues to roll.

Last night, Andreescu came out of a set to beat Elise Mertens (3-6, 6-2, 6-3). On Monday night, she beat American Taylor Townsend (6-1, 4-6, 6-2) during a roller – coaster encounter at a match that culminated when he was in the game. she threw her racket midway through the field after a double foul at the start of the third set.

Prior to that, she had defeated former World No. 1 Caroline Wozniacki in straight sets, and she had easily battled Kirsten Flipkens and Katie Volynets in the second and first rounds, respectively.

And now, a year after losing in the first round of qualifying, Andreescu qualifies for the semi-finals. She will face tonight Belinda Bencic, Switzerland's 22-year-old, whose game is tailor-made for an aggressive and powerful opponent like Andreescu. Bencic eliminated defending champion Naomi Osaka in two straight sets in the fourth round, absorbing and reorienting Osaka's pace. Andreescu has never played against Bencic in a match, but said that they were training together in Toronto.

"I found out that she takes the ball very early, she likes to be very aggressive, she has a very good service," Andreescu told Bencic. "She's moving pretty well too, so I'm going to do my best to focus on myself and keep doing what I'm doing because I think my game rejects a lot of players."

Off the field, Andreescu is friendly, even adorable. Prior to the tournament, she was probably better known for comforting Serena Williams, who was injured and weeping after she pulled out of the Rogers Cup final. In the field, it offers no comfort of this type.
