2026 RHP/OF Jack McCarthy was another one of the younger prospects to show well at PSA Scout Day. Flashed upside on both the mound and at the dish and it looks right with an athletic, high-waisted frame at 6-foot-1, 150-pounds. Smooth left-handed swing and found the barrel for a ton of line drive contact throughout his round. Works downhill with long levers and body control on the mound. Sat 74-76 T77 with the fastball along with a breaking ball at 64-67mph. Being young, he’s weak right now but projects to be an interesting prospect on either side of the ball.
