2020 Marucci Posey28 Pro Metal USSSA Bat Review
The Posey28 Pro Metal is Marucci's premium one-piece alloy travel-ball bat, built on AZ105 — the brand's strongest aluminum — with a multi-variable wall and AV2 anti-vibration knob. A durable, balanced -10 modeled on Buster Posey's gamer.
The Score
How we score ↗How big and forgiving the barrel is — based on barrel length, construction (one- vs two-piece, alloy vs composite), and how it plays on balls hit off the center. A primary driver of the overall score.
Raw exit velocity and distance. We use measured numbers from freely available independent testing when they exist; otherwise construction and consensus, judged against the certification’s performance ceiling. A primary driver of the overall score.
Comfort and feedback on contact — vibration dampening from the knob/connection, the sting of a stiff one-piece vs a smooth two-piece, and the sound off the barrel. A primary driver of the overall score.
How well it holds up and how the company stands behind it — documented cracking/denting reports, cold-weather behavior, and the brand’s real warranty record. Good to know, but weighted lightly in the score.
Our take on price-for-performance — the overall package weighed against its cost and what comparable bats run. Shown for context; it is NOT factored into the overall score (price changes too often and is personal).
Why this score: AZ105 alloy and the multi-variable wall give the Posey28 Pro Metal excellent durability and solid alloy pop with a forgiving sweet spot, and the AV2 knob improves feel for a one-piece. Swing weight is balanced and quick in the -10. Power and barrel size trail premium composites, but value is good.
Our Review
Marucci's Posey28 Pro Metal brings the brand's top AZ105 aluminum to travel ball in a clean one-piece alloy build modeled on Buster Posey's in-game design. The multi-variable wall thins the barrel for a larger, more forgiving sweet spot, ring-free construction lets the barrel flex without dead spots, and the AV2 anti-vibration knob uses harmonic dampening to soften sting on off-center contact. The -10 swings balanced and natural, which keeps it friendly for younger hitters. As alloy it's stiffer and a touch smaller in the barrel than a premium composite, but AZ105 durability and that clean traditional feel make it a dependable, well-priced travel-ball bat from a preferred brand.
