The drop 8 CAT 9 in USSSA is a 2 3/4 barrel with a great feel, major pop, and some serious industry love. This is the most popular drop 8 on the market due, at least in part, to its price point, player ratings, and brand name status. We love the bat and recommend it to anyone looking to size up from a drop 10 or who wants to try a single piece bat for the first time. It's one of the best-rated bats on the planet. We also love the drop 8 in the shorter sizes---it really helps manage hand sting better for those who can wield it.
