Less lively aluminum baseball bats change game

Last year, the National Collegiate Athletic Association required all aluminum bats used in college play to meet a new performance standard designed to limit the exit speed of the ball off the bat. This year, the National Federation of State High School Associations also has implemented the new standard. With spring training beginning at all levels this month, a WUSTL professor and WUSTL baseball coaches comment on the new bats and how they have affected play.
