Star Olympic swimmer Natalie Coughlin earned two Pan American Games records on Tuesday, and lost them both before the day was out.
Several Pan American Games records fell in the pool on Tuesday, with American Natalie Coughlin unfortunate not to finish the day with one of them.
Coughlin, a three-time Olympic gold medallist, won her women's 100 metres freestyle heat in a Games-best 53.85 seconds in Toronto.
However, her benchmark would last a mere nine hours, as Canada's Chantal van Landeghem claimed it in the final - clocking 53.83secs to edge Coughlin (54.06) for the gold medal.
Coughlin was then a part of the 4x100m freestyle relay team that swam a Games-best 3:37.28 in the heats - however, that record did not last the day either.
Van Landeghem and team-mates Sandrine Mainville, Katerine Savard and Michelle Williams stunned the Americans in the final, clocking 3:36.80 - beating the US team by 0.21secs.
Brazil's Leonardo de Deus touched the wall in a Games record 1:55.01 in the men's 200m butterfly, while his compatriots also registered the best time at the regional Games in the men's 4x100m freestyle relay - winning the final in 3:13.66.
Also in the pool, United States beat Canada 13-4 in the women's water polo final.
Canada were dominant in the rowing, winning three of five golds on offer - which helped them finish the day with a tally-leading 25 gold, 22 silver and 17 bronze.
Neighbours USA are second with 19, 19 and 22 for 60 medals all up - four fewer than Canada - while Cuba (14, 11, 16) are third.
