The Gaels started the season 6–0 with notable wins over USC, California, and Nevada, before a loss to UCLA in the last game ending the unbeaten streak.
But St. Mary's scored first on a Herman Wedemeyer touchdown pass to Denis O'Connor.
Fenimore and Reynolds added in touchdown runs in the second half as the lineman size started to make a difference, with St. Mary's four turnovers mattering more than Oklahoma A&M's.
Note: Denis O'Connor, St, Mary's QB also played both ways as did Wedemeyer and Fenimore, known as 60-Minute Men in the day.
O'Connor (1944) and Wedemeyer (1943) both played in the East West Shrine All Star game.
