Question: what is the difference between fastpitch and slowpitch bats?
Answer: Though both fast-pitch and slow-pitch regulations mandate a maximum bat length of 34 inches, the difference is the weight. Fast-pitch hitters can use bats with a maximum drop (length minus weight) of 12- or a maximum weight of 22 ounces. Slow-pitch bats can be no heavier than 38 ounces.
