Mexican Olympic medalist Ana Gabriela Guevara won the women's 400m for the third straight time at the Pan American Games on Wednesday, and Brazil's Hudson Souza retained his men's 1,500m title in record time.
Guevara won in 50.34 seconds, edging Christine Amertil of the Bahamas (50.99) and Indira Terrero of Cuba (51.09). Guevara won the race in 1999 in Winnipeg and 2003 in Santo Domingo.
"I dedicate this result to all of those who didn't believe in me anymore," said the 30-year-old Guevara, a 2004 Olympics silver medalist.
Souza broke the 12-year-old Pan Ams record by almost 4 seconds in 3 minutes, 36.32 seconds, ahead of Juan Luis Barrios of Mexico (3:37.71) and Bayron Piedra of Ecuador (3:37.88).
"It was amazing to listen to the whole stadium shouting my name out loud," he said. "This encouraged me."
Souza, who practices at high altitudes in Switzerland and Germany, won the 1,500m and the 5,000m in Santo Domingo in 2003.
Jamaican Deloreen Ennis-London won the 100m hurdles in 12.65, breaking the Pan Am record by .01 seconds. Perdita Felicien of Canada ended with the same time but was second on a photo finish.
Chris Brown of the Bahamas won the men's event in 44.85.
Brazilian Maurren Maggi won the long jump with 6.84m, ahead of countrywoman Keila Costa (6.73). Maggi, who missed the Santo Domingo games because of a doping suspension, had won the event in 1999 in Winnipeg.
