2019 Marucci CAT USA USA Baseball Bat Review
Marucci's first USA-standard youth bat brings its proven AZ105 alloy, AV2 anti-vibration knob, and multi-variable wall design to the youth market in a true-to-scale -10.
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).
Our Review
Marucci's debut USA bat carries over the AZ105 alloy, AV2 knob, and multi-variable wall design from its successful BBCOR and travel lineups. It swings easy and feels true to a -10, with pop about the same as a Slugger Solo -11, which is good for a USA bat. The barrel is a hair smaller at 2 1/2" to keep it light, but don't let that deter you. My son still chose his -12 Rawlings Quatro Pro for most at bats.
