 The college annually played the New York Giants in the late 1880s and into the 1890s at the Polo Grounds and Manhattan is credited by the Baseball Hall of Fame with the practice of the "seventh inning stretch" spreading from there into major league baseball.It is written in the Baseball Hall of Fame that "During one particularly warm and humid day when Manhattan College was playing a semi-pro baseball team called the Metropolitans, Brother Jasper noticed the Manhattan students were becoming restless and edgy as Manhattan came to bat in the seventh inning of a close game.To relieve the tension, Brother Jasper called time-out and told the students to stand up and stretch for a few minutes until the game resumed."
