After a frantic penultimate day of competition on Saturday, the Pan American Games slowed to its inevitable conclusion Sunday but not without a heart-stopping basketball final, which almost saw Mexico pick up its 43rd gold of the games.

FINAL MEDAL TABLE

With the scores tied at 72-72 and 11 seconds to go, Puerto Rico playmaker Jose Juan Barea ran the clock down to two seconds and and netted a vital two-pointer.  It proved decisive.

Canada won the final medal of the games, surprisingly defeating favorites Argentina in the rugby sevens final at the Tlaquepaque stadium. The jubilant Canadians received their medals from David Johnson, the visiting governor general of Canada.

Saturday's action saw Mexico record its best-ever Pan Am medal tally (133), starting with victory by Horacio Nava in the grueling 50-kilometer walk.

In the diving pool, Mexico completed a clean sweep of all eight gold medals in the competition, as Ivan Garcia won the men's 10-meter platform event and Paola Espinosa and Laura Sanchez the women's three-meter synchronized springboard final.

A day at the Pan Am Games wouldn't seem normal without golds from Team USA athletes and Saturday didn't disappoint.  Christina Mccrea won the individual show jumping event at the Guadalajara Country Club, the women's team epee and men's team sabre overcame their Canadian opponents to win both fencing golds of the evening session, and there was also a gold in karate for Shannon Nishi.

A low-scoring water polo final saw the United States overcome Canada 7-3, while on Lake Zapotlan in Ciudad Guzman U.S. rowers won the women's K1 200 meters final.

Canada's rowing teams triumphed in the men's C1 200 meters and K2 200 meters. And Mandy Bujold won gold for Canada in the penultimate bout in the Expo Guadalajara boxing arena. (Unfortunately, the Mexican fighter couldn't overcome her Puerto Rican opponent in the final bout, much to the displeasure of the partisan crowd.)

The only black spot for Canada during the final weekend was the news that water skier Aaron Rathy failed a drug test and was stripped of his wakeboard silver medal.

Games doping officials said Rathy had tested positive for the stimulant methylhexaneamine.

In a written statement by Canada's Water Ski Association, Rathy apologized and explained that he had bought the nutritional supplement Oxy Elite Pro from a GNC store without realizing that it contained the banned substance.

On its website, Oxy Elite's manufacturer advises athletes to check with their federations before taking the supplement.
