Watch: Stroman's 9-year-old brother shows off silky stroke in batting cage

Marcus isn't the only one in the Stroman clan who takes spring training seriously.

On Tuesday, after the Toronto Blue Jays' ebullient right-hander worked out and snapped some photos at his club's spring complex in Dunedin, Fla., his younger brother put in some work, too, refining that left-handed stroke of his in the batting cage.

No word yet, though, as to whether Duke University has offered the pre-pubescent stud a scholarship.
