LATEST PG SHOWCASE REPORT
2026 PG Coastal Indoor Showcase
Mark Williams Jr. is a 2027 3B/RHP/UT with a 6-3, 200 lb. frame, who attends Southern Md Christian Academy. He has an athletic frame that combines present strength with projectable size. On the infield, he moves well, has advanced feel for angles, and can change arm slots effectively, making him a versatile corner option with a clean transfer and consistent accuracy. In the outfield, he has a strong over-the-top release, generates good carry on throws, and has enough athleticism to handle a corner spot while maintaining arm strength. At first base, his actions are smooth, he adjusts well to different angles, and his hands are quick and sure. Offensively, the left-handed hitter has excellent hand speed, a simple and repeatable load, and the ability to lift the ball consistently gap-to-gap. His barrel control and feel for the middle of the field give him strong run-producing potential, and his power projection, combined with his overall athleticism, make him an exciting player with a high ceiling. Great student. Named to the 2026 PG Coastal Indoor Showcase Top Prospect List.
