Herrera signed with Kansas City as an international free agent in 2006, and made his MLB debut with the team five years later.
His electric fastball -- which can exceed 100 mph -- earned him a spot on the Dominican Republic 2013 World Baseball Classic team, which won the tournament in San Francisco.
Herrera comes from Tenares, a town in the Hermanas Mirabel province of the Dominican.
