NBA Rookie of the Year Andrew Wiggins will be out to lead Canada to glory at the FIBA Americas Championship.

The Minnesota Timberwolves guard had 20 points as Canada beat Puerto Rico 78-72 to win the Tuto Marchand Continental Cup, a lead-up tournament, for the first time on Wednesday.

Rio 2016 places are on the line in Mexico, where 10 teams are gathering for the event starting Monday.

As hosts of the Olympics, Brazil have already qualified for the Games - but they are still taking their place.

United States, also through as world champions, are exempt, while Oceania champions Australia have also booked one of the 12 spots available at the Olympics.

A youthful Canada, led by 20-year-old Wiggins - the 2014 number one NBA draft pick - enjoyed his debut against Argentina on Sunday.

"It felt good," Wiggins told the FIBA Americas website.

"It felt like I was playing [at] home, playing for my country with pride, just trying to win."

Wiggins' Wolves team-mate Anthony Bennett is also part of the Canadian team, who have nine NBA players.

Melvin Ejim and Andrew Nicholson (Orlando Magic), Cory Joseph (Toronto Raptors), Kelly Olynyk (Boston Celtics), Dwight Powell (Dallas Mavericks), Robert Sacre (Los Angeles Lakers) and Nik Stauskas (Philadelphia 76ers) join Wiggins and Bennett.

Canada are two-time runners-up, most recently in 1999, and are with Cuba, Puerto Rico, Argentina and Venezuela in Group B.

Four-time champions Brazil are in Group A, alongside Mexico, Panama, the Dominican Republic and Uruguay.

Mexico are the defending champions, while the Dominican Republic were fourth two years ago.

Runners up in 2013, Puerto Rico are set to be led by Dallas Mavericks point guard JJ Barea, while Argentina - third in the previous edition - have Toronto Raptors power forward Luis Scola.

Four of the five teams from each group advance to the second round, with records carried over - other than the games against the eliminated teams.

Countries then face the four teams they are yet to meet before four reach the semi-finals and the finalists seal their place in Rio.
