Eight heats took place, and the top two finishers automatically advanced. Those with the four fastest third-place times also passed through.
Hungary's Liu Shaolin won Heat 1 by more than a second. He missed out on a gold medal last Monday due to penalties assessed during the 1000m final, so the title went to China's Ren Ziwei. Ren finished first in Heat 2.
Canada's Steven Dubois, the 1500m silver medalist, took the victory in Heat 3 with the fastest time of the opening three races. He got out in front early from the inside starting position.
Denis Nikisha and Abzal Azhgaliyev of Kazakhstan both won their respective heats.
Hwang finished in second place behind Azhgaliyev, while Pivirotto crossed the line third. The American advanced with a qualifying third-place time.
