Seattle Mariners designated hitter Edgar Martínez was presented with the 2004 Roberto Clemente Award, having announced his retirement one month before. The ceremonial first pitch was thrown by arguably the Cardinals' best-ever position player, Stan Musial, and caught by arguably their best-ever pitcher, Bob Gibson. "The Star-Spangled Banner" and "God Bless America" were sung by country music singer Martina McBride and singer–songwriter Amy Grant respectively. During the game, a sign for the fast-food restaurant Taco Bell that measured and read "Free Taco Here", was hung approximately from home plate, over the left-center field bullpen. Taco Bell promised that, if the sign was hit by a home run ball, they would give a free "Crunchy Beef Taco" to everyone in the United States.
