Dennis Colleran

Draft Prospects

• Ranked #209 prospect in 2021 draft
  Colleran is one of the younger pitchers in the high school class, turning 18 after the draft in August. Despite his youth, Colleran has good size, strength and some of the best stuff among Northeast pitchers this year, albeit with unconventional mechanics. He pitches exclusively from the stretch, starting his delivery with a big leg kick before reaching back with a long arm swing and slinging the ball from a low three-quarters slot. It's unusual and leads some scouts to think his future is in relief, but Colleran attacks hitters with a mix of two- and four-seam fastballs that are typically in the 90-93 mph range and can climb to 96 with good arm-side movement. Colleran is already fairly physical, but between his youth and an explosive lower half, there could be more velocity gains coming. His low-80s slider was his out pitch last summer, and while it's not consistent yet, it's been solid-average at times with tight spin to project for more. His firm changeup was more of a distant third offering that he didn't throw much last summer, but this spring he has sprinkled it in, showing better action and more separation off his fastball. Colleran had erratic control early this spring, but he threw strikes consistently at big events last summer and was the Most Valuable Pitcher at the Perfect Game World Wood Bat Association World Championship in Jupiter, Fla. in October.
