During the Olympic Trials, sprinter Yohan Blake beat fellow Jamaican competitor Usain Bolt in both the men's 100-meter and 200-meter sprints, so he should not be underestimated when time comes for the 200-meter semifinals on Aug. 8.

In his heat, Blake came in first place in round one of the men's 200-meter sprint that aired on Aug. 7; he marked 20.38. He came in second to Bolt at the men's 100-meter finals but he might use the semifinals on Aug. 8 as a chance to switch things around and leave Bolt in the dust with a silver medal as he claims the gold for himself.

At the 200-meter trials, Blake, 22, beat world-record holder Bolt and in 2011, he clocked in the second fastest 200-meter time - 19.28. He got his first world title at the World Championships, victorious with 9.82 seconds in the 100-meter sprint.

The London Games is Blake's Olympic debut and the sprinter will compete alongside Bolt in the 4x100- meter relay later in the week.  Bolt and Blake both train together with coach Glen Mills but let us see who has the better skills when it comes to 200-meter sprints.

The 200-meter semifinals air on Aug. 8 at 8:10 p.m. and live stream of the relay can be seen on NBC's official site for the 2012 Olympic Games.
