The Dominican Dart

Did you know there's a relief pitcher in the major leagues, active right now, who throws just as hard as Aroldis Chapman?

It's true. Chapman has averaged 97.8 miles an hour on his fastball this season. Kelvin Herrera, a 22-year-old right-hander who pitches in middle relief for the Royals, has averaged 98.6 on his fastball. Oh, and Herrera doesn't give up many home runs or walks.
