LATEST PG SHOWCASE REPORT
2026 PG National Showcase  
William Haggerty is a 2027 RHP/MIF with a 5-10 190 lb. frame from Rumford, RI who attends Moses Brown. Compact frame with strength throughout. Primary right-handed pitcher, works from a full windup, compact leg lift to balance, longer arm stroke in the back with high level arm speed coming through release. Fastball has heavy sinking action at the bottom of the zone and held low-90s throughout the outing, grabbing 94 mph (2105 RPM). Slider has tons of sweep in the low-80s with confidence spinning it in all counts, rounds out mix with a fading changeup at 84 mph (1010 RPM) that he sells and can throw to both handed hitters. Good student. Verbal commitment to Florida.
