LHP Cooper Harris (Stevenson, 2025) was an intriguing 5-foot-11, 185-pound southpaw that showed some upside in his clean arm. Harris moves with a controlled tempo down the mound, working with a tall/fall lower-half that remains in-line to the plate while striding home, leading with a strong front hip and finishing with a square landing foot. He ran his fastball up to 75 mph, with his four-seam playing straight and his two-seam moving with sinking action. He showed feel for two breaking balls; first being a sharp 1/7 curveball with downer shape at 63-66 mph, and the second being a tight slider with 1/7 shape at times, 67-68 mph. His final offering was a changeup at 70-72 mph, flashing cutting action.
