Track Record: In his DSL pro debut, Diaz--who grew three inches and added roughly 50 pounds in his first year in the Red Sox system--showed the standout power that led the Red Sox to sign him for $1.6 million in 2017. He blasted six homers in 26 games before surgery to remove a broken hamate ended his season.
Scouting Report: Diaz has the size and strength of a middle-of-the-order hitter, but with the swing-and-miss and aggressive approach (23.9 percent strikeout rate, 4.4 percent walk rate) to create risk in his profile. Diaz moved from short to third once in pro ball, and he shows soft hands and good arm strength at the position. His size raises long-term questions about whether he’ll move off the position, and the Sox plan to give him time at both third and first.
The Future: If everything clicks, Diaz could emerge in several years as a third baseman with top-end power, but with his size and his struggles to make contact, his development track may prove deliberate.
There's plenty of risk associated with a player who has yet to play an official game of pro ball, but Diaz showed tremendous size and strength as a 16-year-old July 2 signee by the Red Sox. As an amateur, he was lauded as one of the best hitters in the class and ranked as the No. 7 international prospect in the 2017 class. While he's demonstrated standout power that runs from the left-field line to right-center, the Sox also saw an impressive feel to hit and an ability to impact the ball while generating loft. Diaz has above-average raw power and projects to have 60-grade raw poweronce he's fully developed. He gets in trouble when he hunts for home runs and lets his swing get long. Though scouted as a shortstop, the Sox moved Diaz to third once he entered their system, and the Red Sox believe he has the glove and the plus arm to make the hot corner his long-term home. If that isn't the case, Diaz could move over to first base and have his bat profile at the position. He's posted average run times as an amateur, but could slow down as he gets older.
