LATEST PG SHOWCASE REPORT
2025 PG Chicago Indoor Showcase  
Mason Robertson is a 2027 LHP/OF with a 5-9 160 lb. frame from Oak Creek, WI who attends Thomas More. A good frame with some athleticism throughout. Projects well with room to keep filling out and long levers to the build. Ran a 7.17 60-yard dash. A primary left-handed pitcher who looked the part on the mound. Worked from the third base side of the rubber with a smooth delivery, using a knee-to-chest leg kick. He was explosive at release, getting some push and drive down the slope. He worked in-line with the plate and had a longer, loose, and whippy arm action. Pitched from a three-quarters arm action and was a tough look for the opposition. The fastball worked the low-80s with good arm-side life to it. Showed a slider in the low-70s with 1-7 shape and depth, spinning it into the 2,400s. The breaker had a good horizontal sweep & was a quality offering. The fastball was a good go-to primary, giving him a two-pitch mix to navigate the opposition. Projectable actions & stuff on the mound showed throughout the outing. Also took BP as a left-handed hitter with slightly open feet, high hands, and the back elbow up. Showed a loose stroke with a linear path through contact, staying loose with the wrists. He turned hard and threw the barrel head through the zone with his best results coming working pull-side. Produced an 82 mph exit velocity during PG DK Testing. Great student. Named to 2025 Chicago Indoor Showcase TP List.
