NEW YORK, NY, USA - Court 10 could hardly contain Bianca Andreescu and the throngs of Canadian fans coming to support the reigning Rogers Cup and BNP Paribas Open champion through her US Open main draw debut.

"These Canadians are wilding," the No.15 seed laughed after ousting American Katie Volynets in straight sets. 

Up against an American in New York, the Ontario native, who won her second career WTA title at home in Toronto, might have expected a Canadian doubles match against Volynets and the packed outer court, but maple leaf flags abounded and cries of "Let's go, Bianca!" far outnumbered any attempted "USA!" chants.

"I think it's really nice to have the crowd support, especially playing an American player. So, yeah, and I think it gives me more motivation to do better in my matches."

Born to Romanian parents, Andreescu - who spent part of her childhood and began playing tennis abroad in Pitești - is likely to experience the sort of fervent support that former World No.1 Simona Halep both enjoys and has come to expect.

"It's nice to see this," Halep said back in 2016 when she played in Indian Wells. "It's nice to play with so many people around you, but sometimes you can feel the pressure that you have to win for them."

Combine the Canadians, Romanians, and the general interest in Andreescu's rapidly rising profile, and the 19-year-old should be able to secure a full house in just about any venue she plays.

"They're coming everywhere," Andreescu echoed on Tuesday. "It's really nice to see all of the Canadians cheering me on in different cities. It's really nice."

Like Halep, the youngster will have to adjust to the potentially raucous atmosphere her tennis attracts, noting the various things she heard as she eased through her first win at the USTA Billie Jean King National Tennis Center.

"People were saying a lot of things. I wasn't really focusing on that. I think one fan said 'Stay calm,' or something, she said, reflecting with a smirk, "Yeah, I try my best to stay calm, but that's just who I am. I just try to bounce back as soon as I can after I get mad at myself."

Fresh off a minimally frustrating victory, Andreescu will perhaps face a more even crowd when she - weather permitting - takes on the all-American doubles team of Whitney Osuigwe and Taylor Townsend alongside countrywoman Sharon Fichman on Wednesday afternoon, but it will likely take more than a light drizzle to dampen the Canadian fans' spirit.
