MARK DOUGLAS
Mark Douglas has put together one of the more impressive developmental arcs in the 2028 class. The Cardinal Newman right-hander and third baseman added significant velocity, improved his secondary pitches, and continued to show two-way upside before committing to UCLA.
A projectable 6'3", 190-pound athlete with a loose arm and a four-pitch mix, Douglas has steadily climbed the velocity chart across multiple Prep Baseball events while also producing loud exit velocities at the plate.
Douglas’s fastball velocity has jumped dramatically over the past year, climbing from the mid-70s into the upper-80s with a major increase in spin.
