CYO of Long Island requires the home team to lead both teams in prayer at the begining of a contest.  Below are two options which can be read.

Prayer of the Sportsman

Dear Lord,
In the battle that goes on through life,
I ask but a field that is fair,
A chance that is equal with all in the strife,
The courage to strive and to dare.
If I should win, let it be by the code,
With my faith and my honor held high.
If I should lose, let me stand by the road
And cheer as the winners go by.


Athlete's Prayer

God, let me play well but fairly,
Help me to learn something that matters once the game is over.
Let competition make me strong but never hostile.
Always let me help my opponent up.
Never catch me rejoicing in the adversity of others.
If I know victory, allow me to be happy;
if I am denied, keep me from envy.
Remind me that sports are just games.
If through athletics I set an example, let it be a good one.
