Scouting Report

Scouting grades: Hit: 50 | Power: 60 | Run: 30 | Arm: 60 | Field: 55 | Overall: 55

Though the Red Sox picked 26th in the 2018 Draft, they still came away with one of the best power hitters available in Casas, who signed for $2,552,800. He led the U.S. 18-and-under national team in homers and RBIs in both 2016 (as its youngest player) and 2017, winning 18U World Cup MVP honors and the World Baseball Softball Confederation player of the year award in the latter year. Originally set to graduate from high school in 2019 before reclassifying for the 2018 Draft, he played just two games in his pro debut before tearing a right thumb ligament while diving for a ball at third base.

While Casas has as much raw power as anyone in the 2018 Draft class, he's more than just a masher. His 6-foot-4 frame comes with a naturally long swing, but he has no difficulty making repeated contact because his feel for hitting and his plate discipline are very advanced for a teenager. And that contact is loud contact, the product of bat speed, strength and leverage from the left side of the plate.

For his size, Casas moves well and is relatively athletic, though he projects as a well below-average runner. The Red Sox are committed to trying him at third base and he has a strong arm that clocked low-90s fastballs when he pitched as an amateur, though most scouts think his size and lack of quickness will land him across the diamond. He improved his conditioning as a high school senior and has soft hands, enhancing his chances of becoming a solid defender at first base.
