 Strike three, you're out. As baseball is in full swing, NHTSA is highlighting pitchers who are clock-throwing the fastest speed in the history of the game. The year was 1997 when Rob Nen, a closer for Florida, threw this historic pitch when he unleashed a fastball clocked at 102 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.
