Brazil, Canada, Cuba and hosts Colombia were convincing winners on the opening day of the FIBA Americas Championship for Women.
The side that finishes top of the podium at this event will earn a trip to the London Games, while the teams that come in second and third will claim places at the FIBA Olympic Qualifying Tournament for Women.
Brazil played the second game of the day and thrashed Paraguay 117-34 in Group B.
Center Erika de Souza led Brazil with 18 points and eight rebounds.
The game was effectively over by the end of the first quarter when the Brazilians had a 28-5 lead.
"I am delighted with the outcome of the game," De Souza said.
"We earned the win by a good margin and now it's time to start thinking about the game tomorrow against Canada."
Canada delivered a first-quarter knockout against Mexico.
Allison McNeill's side stormed into a 19-4 lead and rolled to a 72-45 triumph.

Teresa Gabriel, the Canada point guard and captain, said: “We came out strong and executed fairly well.
"Defensively, we were very good, holding Mexico to nine points in the first half.
"We shot the ball well and we all brought energy, which is something we’ve sometimes been lacking. It was a good first win.”
In the first game of the day, the Cubans trailed Puerto Rico 27-26 at half-time but pulled away in the second half and
