Wooden bats (often made from ash, maple, or birch) are prized for their traditional feel but can break easily. Aluminum and composite bats provide a larger sweet spot, increased durability, and higher performance. The moment of inertia (MOI) affects how easily the bat can be swung, with lighter bats offering speed and heavier bats delivering power. Modern technology has enabled the creation of bats that optimize both bat speed and ball exit velocity, furthering the quest for perfect contact.
