If there was any doubt that the men's 200m finals would be a two-man race, that was firmly erased Wednesday night in London as Jamaicans Usain Bolt and Yohan Blake cruised to victories in their semifinal heats while barely breaking a sweat.
Blake had the fastest time, a 20.01, and looked like he was jogging for the final 40 meters. Wallace Spearmon was right behind him (20.02 seconds), and will be the only representative of Team USA in Thursday's finals (3:55 p.m. ET).
Bolt appeared to be out for a casual jog and still won his heat easily, cruising past the rest of the field in 20.18 seconds. South Africa's Anaso Jobodwana finished second behind Bolt to automatically qualify for the finals.
The Netherlands' Churandy Martina won the third heat, in 20.17 seconds, advancing to the final along with Jamaica's forgotten runner, Warren Weir.
In Thursday's final, Bolt will attempt to do something never accomplished before in the Olympics: win gold in both the 100m and 200m in back-to-back Games.
