Jonathan Robert Papelbon is the closer for the Boston Red Sox. He bats and throws right-handed.
Papelbon was drafted by the Boston Red Sox in 2003 out of Mississippi State. Papelbon throws a fastball clocked as high as 100 mph, typically hitting the top-90s, with great command. He complements his fastball with a devastating splitter, and may throw the occasional slider, changeup, or curveball with far less frequency.
