Mikayel Koloyan, a swimmer representing Armenia, failed to make the grade in the 100 meter men’s freestyle competition with a disappointing 53.82 second showing in his heat.

Only eleven others of the 52 total contestants had slower meets than Koloyan.

Nathan Adrian of the U.S. qualified fastest in the 100-meter freestyle preliminaries at the London Olympics on Tuesday, topping a tightly bunched field that included three ties.

Adrian won his heat in 48.19 seconds while swimming in a lane next to world-record holder Cesar Cielo of Brazil. Cielo, the 2008 bronze medalist, tied for 10th with Konrad Czerniak of Poland in 48.67.
