After years of research, testing, and consulting the game’s best players, not only did we improve the hottest bat in the game…we added another.

The 2017 CAT7 line is built with AZ4X alloy, the strongest and most responsive in the Marucci arsenal. The increased strength and response rate allowed a barrel design with up to 7 variables of wall thickness without any internal rings or governors. The result? A sweet spot that’s double the size of the CAT6.


Upgraded with the new AZ4X alloy, the strongest alloy in the Marucci arsenal, and a sweet spot twice as large as its predecessor, the CAT7 is built to explode with unrelenting fury. The precision-balanced barrel and one-piece alloy design oer a clean, consistent swing to control the wrath of this ultra-responsive rainmaker.
