| Summary: The delivery traits are what stand out first with Giese. Clean arm action, solid extension with the release well out in front of the frame, feel for tempo and the ability to repeat his operation across multiple innings — the premium pitching prospect markers of polish and pitchability are already present in a way that typically takes years to develop. The high spin on the fastball helps it play beyond its current velocity, sitting 91-94 and touching 95 with the lean, angular frame and boxy shoulders pointing toward significant velocity gains as the body fills out physically. The changeup is the carrying secondary and already the most advanced pitch in the arsenal. Low-80s with late arm-side tail, sink and action that give it plus components when the feel is there — the pitch separates the profile from a typical projectable prep arm and gives the evaluation a genuine weapon to anchor the secondary mix around. A slider and curveball both show the ability to spin the baseball and repeat the release point to mirror the fastball, though neither has consistent bite yet — the slider is the more likely secondary to develop alongside the changeup as the competition level rises. The mid-rotation ceiling is grounded in delivery traits and pitchability that are already well ahead of where most prep arms operate, with the velocity projection giving the stuff room to catch up to the operation. Cross-checkers tracking the profile throughout the spring speaks to how the combination of feel and projection registers with advanced evaluators — the stuff will continue developing, and the delivery gives it every chance to play when it does. | |||||||||||
