From 2008 to 2016, the number of pitches thrown at or over 100mph has increased substantially. However, it's important to note that since 2014, a large proportion of those pitches have come from New York Yankees pitcher Aroldis Chapman. In 2014, Chapman recorded 395 pitches over 100mph; in 2015, Chapman threw the fastest 101 pitches for the season; and in 2016, Chapman led the league with an average pitch speed of 100.9mph. He threw 976 pitches in 2016 for the New York Yankees and Chicago Cubs.
