Traditional feel. Precise balance. Explosive performance. The Marucci F5 Senior League -5 USSSA Baseball Bat is built for hitters who want speed, control, and serious barrel response. Its one-piece alloy construction delivers the clean, consistent swing feel players trust, while advanced wall engineering expands the sweet spot for maximum damage at the plate.

The multi-variable wall design creates thinner barrel walls and a larger sweet spot without sacrificing durability. Combined with ring-free barrel technology, the F5 eliminates “dead” spots and increases barrel flex for consistent performance across the entire hitting surface. The balanced profile promotes faster swing speeds and greater bat control, making it ideal for players who rely on quick hands and precision mechanics.

Finished with a custom micro-perforated soft-touch grip, the F5 enhances comfort and control for confident swings in every at-bat.
