Knights of Columbus

As of today, there is no official patron saint of baseball. St. Rita is often cited, not so much for her athletic prowess or love for the national pastime (since the 15th-century nun lived several hundred years before the game’s invention), but for her connection to the 2002 film, The Rookie.
While she is a powerful intercessor, Blessed Michael McGivney — a 19th-century Connecticut parish priest on the path to canonization — has more of a claim to the title of patron saint of baseball. After all, he played the game. Moreover, the order he founded, the Knights of Columbus (K of C), has used baseball as a tool for evangelization and charity. Additionally, some of the game’s mightiest heroes have been members — like Babe Ruth, Connie Mack, Nap Lajoie and Joe DiMaggio — who shaped the game into what it is today.
Baseball followed the Catholic priest throughout his life. While attending Our Lady of Angels Seminary at Niagara University, McGivney started in a game between Connecticut and New York seminarians where he batted clean-up, played left field and scored three runs. More significantly, he held the role of vice president for his squad, perhaps his first foray into founding and/or leading groups — skills he would implement when establishing the K of C in 1882.
As a parish priest, he organized baseball games at annual parish picnics in New Haven and Thomaston, Connecticut, and, quite possibly, served as the third-base coach for the local K of C council’s baseball club. (National Catholic Register)
