GUADALAJARA (AFP) - Argentina's men's field hockey team qualified for the 2012 London Olympics on Saturday by defeating Canada 3-1 in the final of the Pan American Games. It was the 10th consecutive time the two squads had met in the Pan Am Games final. Canada won in the 2007 final on penalty shots at Rio de Janeiro. Scott Tupper gave Canada a 1-0 half-time lead but the South Americans answered in the second half with goals from Ignacio Bergner, Pedro Ibarra and Lucas Vila.
