College baseball went to aluminum bats in 1974. What followed was a steady rise in offense, peaking in 1998, when records were shattered, including many at the College World Series that made the game more resemble a slowpitch softball slugfest.
In the title game alone, when Southern Cal beat Arizona State 21-14, nine home runs were hit in what became a genesis for change.
Prompted by NCAA bat legislations, the numbers nationally have swung back toward normalcy, dropping dramatically the past two seasons with the move to a BBCOR standard.
