2023 Mizuno B23 PWR CRBN BBCOR Bat Review
The B23 PWR CRBN is Mizuno's two-piece, all-composite BBCOR flagship, built on Black Onyx Carbon with a Dual Frequency Damper that smooths out contact. It's a clean, balanced composite for hitters who want a forgiving barrel and a quiet feel.
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.
This bat: Black Onyx Carbon barrel with Detonator COR opens a wide zone.
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.
This bat: Low barrel compression gives a hot, lively trampoline once broken in.
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.
This bat: Dual Frequency Damper makes contact notably quiet and smooth.
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.
This bat: Two-piece composite; sound but break-in and care matter.
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).
This bat: Strong composite build at a price below the best-known flagships.
Why this score: An underrated, smooth two-piece composite with a forgiving barrel and excellent vibration control. It loses a little to the universal composite break-in and to thinner brand support in BBCOR than the category leaders.
Our Review
Mizuno's PWR CRBN is the all-composite top of the B23 BBCOR line, using Black Onyx Carbon Composite in a two-piece build. The barrel gets Detonator COR technology, which lowers barrel compression for a hotter trampoline and a deep, resonant crack on contact. Connecting the barrel and handle is Mizuno's patented Dual Frequency Damper, a two-piece system that reduces vibration and tunes flex so mishits feel muted rather than stingy. The swing weight is balanced, making it a versatile fit across the lineup rather than a dedicated power stick. Like any composite, it wants a short break-in before it fully opens up. Mizuno isn't the first brand most BBCOR shoppers think of, which has historically kept the PWR CRBN underrated and competitively priced for the construction it offers.
