Mine used the end loaded yellow and black Rawlings Quatro....loved the bat, had great pop, but zero durability....junior and senior year went to a black and red Easton, forgot what its called. (Many players used it)....in college he's using the Green Easton (the one that is a clone of the classic green Easton)...I see lots of players using The Goods and the Marucci CAT at the college level.
