TIJUANA (Mexico) - Brazil and the United States won their semifinal duels Saturday at Auditorio Zonkeys in Tijuana, Mexico and advanced to the FIBA U18 Americas Championship gold medal game.

Brazil 78 - 77 Canada

In an absolutely wild comeback and an even more dramatic finish, Brazil shocked Canada on Saturday, 78-77, to advance to the gold medal game against the United States.

The South Americans went down 22-6 to start the game before staging an improbable run in the third quarter that saw them briefly take the lead.

Canada managed to end the stanza on top and even led 71-66 with 5:46 to go in regulation, but Vitor Galvani’s uncorked a 9-0 run to set up a nailbiter of a finish.

Vasean Allette tied the game at 77 with 43 seconds left and Dylan Grant had a chance to win it, but his three-point shot rimmed out and Bubu Benjamin inadvertently fouled Gabriel Caldeira. With Canada in the bonus, the Brazilian made the first attempt and missed the second one, but Vitor Farias Cardoso grabbed the offensive rebound and was promptly fouled.

Farias Cardoso wound up missing both shots at the charity stripe, but Canada couldn’t get a shot off before time expired.

It was Brazil’s long-range attack that allowed them to get back in the game, as they went 14/44 from beyond the arc.

Reynan Camilo Dos Santos (22 points and five assists), Caldeira (16 points and six rebounds), Eduardo Bersh (14 points and eight rebounds) and Guilherme Tesch (11 points) each made 3 three-pointers, an impressive feat in a game where both teams shot under 40 percent overall from the field.

Galvani’s boys were also more efficient and careful with the ball, as they only committed 10 turnovers and dished out 15 assists on 28 made baskets.

This allowed Brazil to compensate for big deficits on the boards (57-39) and points in the paint (42-20), where Michael Nwoko dominated.

The Canadian center finished with a 15-point, 13-rebound double-double. Elijah Fisher added 10 points, while Allette led the way with 22, five rebounds and five assists for Patrick Bruce Tatham’s squad.

Canada will now face Argentina in the bronze medal game on Sunday.
