Ten days ago, 18-year-old Canadian wild card Bianca Andreescu captured one of the biggest titles on tour, at the BNP Paribas Open. She's since had to retire from the fourth round of Miami, but the Canadian-teen mantle has by no means been abandoned.

On the top half of the Miami men's draw, Felix Auger-Aliassime, also 18, has won six consecutive matches to make the quarterfinals; he had to come through qualifying despite being ranked No. 57. Once into the main draw, he knocked out Casper Ruud, Marton Fucsovics, Hubert Hurkacz and Nikoloz Basilashvili.

He takes on No. 11 seed Borna Coric in quarters on Wednesday night, in what could be a high-reward match, as the highest seed remaining on his side of the draw is No. 7 John Isner.

On the bottom half, meanwhile, Denis Shapovalov, 19, is representing Canada in the quarterfinals as well. So far, he's gotten past past Dan Evans, Andrey Rublev and, in a third-set tiebreak in the early hours of Wednesday morning, Stefanos Tsitsipas.

He'll face another young player on the rise, Frances Tiafoe, on Thursday, with a looming potential semifinal against either Roger Federer or Kevin Anderson.

Canadian tennis, it's safe to say, is in good hands—or, at the very least, a lot of hands.
