All baseball and softball bats used in Willamette Valley Little League practices and games must have one of the following printed on the bat:

The Bat Performance Factor (BPF) Rating, not exceeding 1.15 BPF.
OR
It must state "Approved by Little League."

Official rules state that for 2009, only bats with the BPF rating printed on the bat (no stickers) not exceeding 1.15 BPF will be allowed, but for this year, we are allowing a "phase out" of bats without the BPF printed, as long as the bats say Little League Approved.
