Baseball Bats Jack MacKay Jr., who designed high performance metal bats for Louisville Slugger for ten years, sent a petition to the Consumer Product Safety Commission last week, asking for a recall of metal baseball bats. MacKay says metal bats have become too dangerous to players. The original reason for metal bats was durability and safety, but they've been redesigned to hit the ball farther and faster. MacKay also says metal bats "juice" up averages and affect the integrity of the game. Noah talks to MacKay about his concerns.
