Group urges smokeless-tobacco ban for MLB teams

Televisions on Thursday will broadcast the usual iconic images of baseball's opening day: fans cheering from the stands, umpires making close calls at the plate, and players in the thick of the game, spitting tobacco juice.

With smokeless tobacco use spiking among high school boys - a reported 36% increase since 2003 - public health officials are targeting their role models to set a healthy example, and calling for a ban on tobacco at major league ballparks.
