Basketball In 1932 St. Patrick (at the time called St. Patrick Academy) won the National Catholic Interscholastic Basketball Tournament. The tournament was hosted by
Loyola University, and it invited high schools from across the country, including top teams in
New York,
Texas, and
Indiana, all of which were considered powerhouse states for basketball at the high school level. St. Patrick was originally not invited to play in the tournament, but was called in last minute as a substitute when an originally schedule team could not make the tournament. The national champion Shamrocks defeated the now closed St. Mel (Chicago) Knights 22–20. A young
Ray Meyer, famous DePaul University men's basketball coach, lead the Shamrocks with 12 points. In 1949 St. Patrick captured the Chicago City Championship crown, which had the Chicago Public League champion against the Chicago Catholic League champion. St. Patrick defeated
Leo High School 47-35 securing them their first Chicago Catholic League title. St. Patrick had to play
Tilden High School, the Chicago Public League champion, for the City Championship. At
Chicago Stadium the Shamrocks upset Tilden 54–53. The Shamrocks trailed throughout the majority of the game, but were able to take the lead in the final minute, and completed the historic upset.
Water polo The 90's and early 2000's treated the Shamrocks well in terms of water polo. The team won multiple competitions, with dominate winning seasons. The Shamrocks had multiple state finals appearances, and one state title. The water polo team won the ISA (Illinois Swimming Association) state title in 1997, going 28–0. This was not an IHSA sponsored title, as water polo only became an IHSA sponsored sport in 2001. ==Notable alumni and attendees==
