The four-seam fastball is the most common variant of the fastball. The pitch is used often by the pitcher to get ahead in the count or when he needs to throw a strike. This type of fastball is intended to have minimal lateral movement, relying more on its velocity. It is often perceived as the fastest pitch a pitcher throws, with recorded top speeds above 100 mph. The fastest pitch recognized by MLB was on September 25, 2010, at Petco Park in San Diego by then Cincinnati Reds left-handed relief pitcher Aroldis Chapman. It was clocked at 105.1 miles per hour.
