Summary:
The carrying tool is obvious and loud. The right-handed bat produces elite exit velocities with power that shows up to all fields, and when Alderman is synced, the ball comes off differently than most corner bats. Getting back to full health in 2025 unlocked that impact again, and the results followed — consistent hard contact, game power that translated against upper-level pitching, and stretches where he looked capable of carrying an offense on his own.

The offensive risk lives in the approach. A flatter bat path and deeper contact point have led to elevated ground-ball rates and swing-and-miss, particularly when he expands the zone or gets caught in between. There were real steps forward in 2025 — better strike aggression, improved swing decisions, and more intent to do damage on pitches he can drive — but the hit tool will always be the swing factor. If the chase stays in check, the power plays at an everyday level; if it drifts, the profile can get streaky in a hurry.

Defensively, he moves better than expected underway for his size and has the arm strength to fit cleanly in a corner outfield spot. Reads and routes remain fringy, keeping the defensive value closer to serviceable than impactful, but the bat is asked to carry the profile anyway. The overall look is a power-over-hit corner outfielder with real everyday upside tied directly to the approach — a middle-of-the-order threat when locked in, and a dangerous slugger even if the offensive consistency comes in waves.
