The Marucci Adults' F5 Senior League Bat -10 gives you the ability to do some heavy damage at the dish. The one-piece aluminum alloy construction withstands wear and tear while feeling lightweight, and the micro-perforated, soft-touch grip helps you securely hold onto the bat and swing. A ring-free barrel has no "dead" spots to make sure every swing gives the ball momentum when hit, and the multi-variable wall design has an expanded sweet spot to reduce vibration for control.
