LATEST PG SHOWCASE REPORT
2022 Great Lakes Indoor Showcase (Saturday)  
Jack Heffernan is a 2024 1B with a 6-3 210 lb. frame from Palos Park, IL who attends Brother Rice. Big and strong build, stands out physically. Right handed hitter, hits from a straight stance with a short and compact swing for his size, can get downhill at times, showed the ability to get some jump off the barrel to the pull side and to mid field, has the strength and barrel control to continue to improve as a hitter with repetitions and developing athleticism. 8.20 runner in the sixty. Primary first baseman on defense, was comfortable moving to the ball, fielded the ball cleanly with balanced step by step actions. Bat is his tool. Good student.
