 Strike three, you're out. As baseball is in full swing, NHTSA is highlighting pitchers who were clock throwing the fastest speed in the history of the game. The year was 2010 when Aroldis Chapman, a rookie pitcher for Cincinnati, unleashed a fastball clocked at 105.1 miles per hour. It's okay for pitchers to be clocked doing over 100 miles per hour on the mound, but on the road, when you speed, you put everyone on the road in danger. One way or another, speeding catches up with you. Paid for by NHTSA.
