Bill Self’s United States squad was finally tested at the U18 FIBA Americas. Thanks to one of Self's soon-to-be KU players, his team passed with flying colors.

In a tournament semifinal against Argentina, a 104-92 U.S. win, it was five-star KU guard Quentin Grimes who led the way, going off for 26 points, eight rebounds, four assists and a steal in 28 minutes of action. Grimes didn’t commit a turnover in the outing and had eight points in two assists in the fourth quarter as the U.S. withstood an offensive flurry from the Argentinians.

And he was aided by some big-time performances.

After Argentina cut the U.S. lead to nine in the final period, it was Jeremiah Robinson-Earl (10 points, seven rebounds) and Illinois-committed Ayo Dosunmu (13 points, four assists) who helped push the margin back out to double-digits.

North Carolina-committed Coby White also added 25 points and five rebounds in the contest, while 2019 five-star recruit Matthew Hurt went for 16 points, eight rebounds, three assists, three blocks and two steals. Point guard Cole Anthony rounded out the United States’ double-digits scorers, putting in 10 points, four assists and three rebounds in 21 minutes.

As was the case all tournament, the U.S. had no problem putting points on the board. With the 104-point outing, the U.S. surpassed the 100-point mark in all five games leading up to the gold-medal contest, with a 132-point eruption against Ecuador in the quarterfinals serving as the team’s top mark. Grimes has crossed the 20-point mark twice for the U.S., scoring 20 in the team’s group-stage finale against Puerto Rico in addition to his outing against Argentina.

Now, only one more challenge stands in Team USA's way.

The United States will square off against host-country Canada Saturday night at 7:15 p.m. CT. The game will be streamed on both USA basketball’s Facebook page and FIBA's YouTube channel.

Canada has had similar success rolling through opponents, defeating Argentina by a larger margin (17 points) than the U.S. did (12), and handling Panama (105-39) in similar fashion to the United States' 118-26 blowout victory.

The game should serve as the toughest test the U.S. squad has faced all tournament, with Canada having a talented roster in addition to home-court advantage.

Among the talent on the Canadian roster are five-star recruits in Florida-committed Andrew Nembhard (27th-ranked player in the 247Sports Composite, class of 2018) and shooting guard Addison Patterson (247Sports’ 18th-ranked player, class of 2020). The roster also features a pair of class-of-2019 four-star guards in A.J. Lawson, the 40th-ranked player by 247Sports, and Brewster’s Joel Brown (111th).

Other names to know include Emanuel Miller (three-star class-of-2019 guard), Tyrese Samuel (four-star class-of-2019 power forward) and Jaden Bediako (four-star class-of-2019 center). Jevonnie Scott, who did not appear in Canada’s 95-89 semifinal win over Puerto Rico, has offers from Arizona State and USC, while Jahcobi Neath, who played sparingly, has a pair from San Francisco and Western Kentucky.

The U.S. will be seeking a fifth-straight gold medal in the event.
