St. Alphonsus Athletics offers basketball to boys and girls in grades 5th through 8th. The 5th grade teams participate in the CYO league and are given 8 league games. The 6th through 8th grade teams participate in the CSAL league and are given 12 league games. At times, tryouts for the CSAL teams are necessary due to the fact that only one team for each grade for each school is allowed in the league. At those times, every effort will be made to fill CYO teams for those student-athletes wishing to participate in basketball. Many tournaments are offered for each league.
