Round robin play at the 2013 FIBA Americas Championship continued Saturday with four games, including an exciting contest between Puerto Rico and Canada. Behind former NBA guard Carlos Arroyo, the Puerto Ricans dominated the fourth quarter of a 83-67 win to stay unbeaten in Group A.

The top four teams from Groups A and B will advance to the second round, which begins Sept. 5 from Caracas. Ultimately, the final four remaining teams in the knockout stage will receive invitations to the 2014 World Cup. Here are the full results from Saturday's slate in Venezuela.

Puerto Rico 83, Canada 67: After trailing in the final seconds of the third quarter, Puerto Rico found its footing in time to crush Canada by 16 points. The late rally appears to be starting a theme for the team after outscoring Brazil by 10 points in the final quarter of a 72-65 to open the tournament.

Arroyo led Puerto Rico with 20 points and four assists, including a 4-of-8 effort from beyond the arc. Former New York Knicks forward Renaldo Balkman recorded a double-double with 18 points and 11 rebounds in just 25 minutes of action, hitting 8-of-10 free throws while his teammates shot an ugly 13-of-24.

Magic forward Andrew Nicholson and Cavaliers forward Tristan Thompson combined for 41 points and 16 rebounds for Canada, but their teammates couldn't keep up. Those two NBA players shot 12-of-24 from the field, but the other nine players on the roster shot a combined 11-of-42.

Uruguay 68, Jamaica 66: Despite shooting a miserable 29 percent from the field, the Jamaicans nearly stole a victory from Uruguay on Saturday. Sloppy fouls and turnovers practically cost Uruguay what should have been a rather easy contest.

Beating a team that can't shoot should've been a walk through the park, but 19 turnovers and 26 fouls put Uruguay in a much tougher position. Jamaica had a 24-10 advantage on free throws made in the game, which almost entirely explains why this game wasn't a complete blowout despite the shooting percentages.

Big games from Esteban Batista and Leandro Garcia powered Uruguay's offense, combining for 42 points on 17-of-31 shooting. Batista also grabbed 14 rebounds, powering a much-needed advantage on the boards for the team. Former Cavs forward Samardo Samuels led Jamaica with 19 points and six rebounds.

Dominican Republic 91, Argentina 72: Once a serious powerhouse on the international basketball stage, Argentina is clearly no longer where it used to be. Meanwhile, the Dominican Republic appears to be emerging as a legitimate player on the scene.

Even without big names like Al Horford, Francisco Garcia and Charlie Villanueva, the Dominicans crushed a Luis Scola-led team almost across the board. They shot 54 percent from the field, held a 45-30 advantage in rebounding and stifled a talented offense.

James Feldeine, a former Quinnipiac guard, led all scorers with 21 points on 7-of-10 shooting. He got help from big man Jack Martinez, who contributed 12 points, 14 rebounds and three assists. For Argentina, Scola had a rough game, finishing with 13 points and seven rebounds but an ugly 4-of-18 shooting performance.

Venezuela 75, Paraguay 70: The Venezuelans rallied in the second half to pick up a big win on Saturday. Axiers Sucre led a balanced scoring attack with 15 points and nine rebounds, anchoring the paint on both ends of the floor. Gregory Vargas and Donta Smith both chipped in with 14 points each.

Guillermo Araujo starred for Paraguay, scoring a game-high 22 points on 8-of-13 shooting. His performance on the offensive end would prove to come up just short, though, and 16 turnovers loomed large.
