NEW YORK (AP) -- Major league baseball teams will pay tribute to the U.S. armed forces and the nation by having "God Bless America" sung during the seventh-inning stretch of all home openers. While the song had been part of all games since the Sept. 11 attacks, it will be sung this season only at the home openers, Sunday games and holidays, the commissioner's office said Friday. Baseball also announced an agreement with Armed Forces Radio and Television Service to carry eight to 10 games each week during the season, starting with Sunday night's opener between Texas and Anaheim.
