The Red Sox went back-to-back on high school players as they drafted Calderon in the 19th round. Calderon is a 19-year-old pitcher out of Puerto Rico and is smaller than the other pitchers taken by Breslow. Currently, he stands 6 feet and weighs 160 pounds but should be able to add to that as he grows and adds muscle.

He has a three-pitch mix currently that is made up of a fastball that topped out at 93 mph in January, a cutter and a slider.

He also played outfield, though there seems to be no interest by the Red Sox in trying him as a two-way player. He currently has a commitment to Dodge City Community College.
