Pending Rules for 2025 season. Historically bats rules have been mixed.
Puyallup Rec League:
Pending Rules for the 2025 season. Historically has not allowed USSSA 1.15BPF bats.
BBCOR: Used in High School and Middle School ball. These bats have a 0.5 BPF, normally only come in Drop -3 weights, and will be slightly heavier than USA and USSSA bats.
Wood: Has the lowestpop of all bats and can be used in any game. Composite wood bats like Baum bats are considered legal.
USA: Has a wood like performance rating with slightly more pop. These bats are legal for almost all tournaments and little league games. Some school baseball teams may not allow them.
USSSA 1.15 BPF: Has the most pop of all the bat certifications with a 1.15 BPF. Only legal in certain tournaments. USSSA 1.15 BPF bats cannot be used in Little League or School Ball.
Bat Drop:
A bat’s drop is the difference between the length of the bat in inches and its weight in ounces. It’s also known as the length-to-weight ratio. The drop is always shown as a negative number.
For example:
A 30-inch bat with a -10 drop weighs 20 ounces (30oz – 10 = 20oz).
A 30-inch bat with a -5 drop weighs 25 ounces (30oz – 5 = 25oz).
Drop weight and player size
Larger, stronger players tend to prefer bats with a lower drop weight, which can increase power. Smaller players can benefit from bats with a higher drop weight, which can help with bat speed.
Material:
Ash (Wood)
A porous, lightweight wood with a unique grain structure that provides flexibility. Ash bats are known for their forgiving nature and “trampoline effect” when struck.
Maple (Wood)
A dense wood with a tight grain structure that gives maple bats their stiffness and “pop”. Maple bats are a popular choice among MLB players and are known for their durability.
Birch (Wood)
A soft but durable wood with a tight grain structure that’s similar to maple. Birch bats are lighter and more flexible than maple, but harder and more powerful than ash.
Alloy (Metal)
Have a heavier, stiffer feel than composite
Very Durable
No break-in time needed
Composite
Generally have a lighter swing weight
More forgiving than alloy
Large sweet spot
Limited Durability
Needs to be broken in.
Construction 1-piece and 2-piece bats:
One-piece bats are made from a single piece of material, while two-piece bats are made from two separate pieces that are fused together. One-piece bats tend to be more durable.
Performance
One-piece bats are stiffer and transfer more energy to the ball, while two-piece bats flex more and increase bat speed.
Feel
One-piece bats provide more direct feedback, while two-piece bats feel less stingy and have less vibration.
