Andreescu faced Belinda Bencic in a semifinal match Thursday night.
The 19-year-old Canadian, playing in her first Grand Slam quarterfinal, advanced to the semis of the U.S. Open on Wednesday in a comeback 3-6, 6-2, 6-3 victory over Belgium's Elise Mertens.
Bianca Andreescu is coming off a three sets win over Elise Mertens that took 26 games to decide.

Clijsters was indeed one of the idols who inspired Andreescu's style of play. "And she wasn't. I noticed very early on that she was a born competitor", her coach Bruneau said. During a pre-match interview, Mertens, 23, who was playing on Ashe for the first time this tournament, admitted "It's going to be a hard match, but I'm going to enjoy it". "I am really enjoying my tennis".
Through all of that, and the steep - steep like up the side of a Manhattan skyscraper - climb from 178 in the WTA rankings at the end of a year ago to a guaranteed spot inside the top 10 when this tournament is over, Andreescu has seemed genuinely unfazed by it all. "When I'm on the court in front of these big stages, I'm really good at just blocking everything and staying in the zone".
"The fricking champion of Indian Wells, " said Andreescu, then 18, shortly after becoming the youngest champion at the event since Serena Williams in 1999, and the first wild card to do so. In the victory, Andreescu won 75 percent of her first serve points and 48 percent of her second serve points. "I think that's the motivation enough to keep going", Bencic said. Andreescu got 62 percent of her first serves in play, saved four of her six break points and hit two aces.
After a flawless first set from Mertens, the tide turned in Andreescu's direction in the second when she fired a cross-court forehand victor to break the Belgian at love and take a 4-2 lead.
Now she is one win from a first major championship in her fourth main-draw appearance at a grand slam, breaking a mark held by Maria Sharapova, who won her first at 2004 Wimbledon in her seventh attempt. "I kept that passion going". She ended last season well outside the top 150 in the WTA rankings, but in January she came out firing, winning three qualifiers in Auckland, New Zealand, and then reeling off four straight wins, including over players such as Caroline Wozniacki and Venus Williams, before falling in the final to Julia Georges. "I think it was small points that changed the whole match", said Bencic, who will be ranked among the top 10 next week. "I'm kind of surprised, like I think everyone is".
Her coach Sylvain Bruneau first spotted her raw talent in 2017 when she went on a stunning run in the Fed Cup to take Canada back into World Group II by the end of the same year.
