| Summary: The delivery is the first thing that grabs attention. An efficient mover who covers ground toward the plate while maintaining a closed front side through a cross-body landing — the angle it creates is a feature rather than a concern, generating natural deception that makes the entire arsenal play up beyond the raw grades. A fluid, athletic operation with controlled tempo gives the delivery a repeatability that compounds the overall effectiveness, and a tall release with substantial extension creates a downhill approach that gives the fastball its most dangerous characteristics. The fastball operates in the low-to-mid 90s with impressive spin rates and vertical movement that generates swing-and-miss when located up in the zone — the pitch’s underlying characteristics hold up even when the arm isn’t fully fresh, a sign that the quality is structural rather than situational. The slider is the secondary with the most long-term upside — a tight breaking ball with two distinct planes of movement and sharp action that has flashed plus and plays against hitters from both sides. A hard changeup thrown with strong arm speed and good finish projects toward average or better with continued refinement — a legitimate third weapon developing alongside an already strong two-pitch foundation. The mid-rotation ceiling is grounded in three pitches with above-average trajectories, a delivery that creates inherent deception, and a high-waisted frame still adding strength in meaningful ways. One of the more compelling right-handed starter profiles in the 2027 class with real room to grow into the ceiling. | |||||||||||
