DELCO BASEBALL LEAGUE CREED
The Creed of the DELCO Baseball League is the Connie Mack Sportsmanship Creed: “I promise to play the game to the best of my ability at all times. I will always play to win, but if I lose, I will never look for excuses which would detract from my opponent’s win. I will always abide by the rules of the game on the diamond as well as in the daily life. I will never gloat in victory nor pity myself in defeat. I will judge a teammate as an individual and never on the basis of his race or religion.”
