Is he playing Little league Sr division or travel? He wont need USA bat if playing travel, USSSA bats have much more pop than USA. 31" -5 is usually appropriate for 8th grader moving into HS. Maybe big 7th grader, although we like light bats to increase your bat speed
I started my son at 12/13yrs. old with a drop -5...Get him used to the drop in weight now...If he plans on playing high school...And if hes playing travel...Also depending on his own weight to heighth, strength ratio....I hope this helps you
