Brother Jasper of Mary, FSC (July 1, 1829 – April 4, 1895) was an American baseball coach and administrator at Manhattan College.
Jasper was born Joseph Brennan on July 1, 1829, in County Kilkenny, Ireland.
[3] In 1882, during the seventh inning of a game against the New York Metropolitans, Jasper instructed restless students to stand and stretch until play resumed.
Although it is not the only origin story for the seventh-inning stretch, former National Baseball Hall of Fame and Museum curator Ted Spencer said that it was the one with the "most substance [and] is the one best documented".
[4] Jasper died of "congestion of the lung" on April 9, 1895, and was buried at Calvary Cemetery in Queens.
