De Smet Jesuit Spartans compete in ten spring sports: baseball, track & field, tennis, golf, volleyball, lacrosse, water polo, inline hockey, ultimate and rugby. The opportunities to get involved in a spring sport are numerous. On any given day, De Smet Jesuit is a hub of activity. Track & field and rugby are no-cut sports, which keeps with the school's policy of offering at least one no-cut sport per season. The Spartans compete in the highly competitive Metro Catholic Conference (MCC), and all but lacrosse, inline, ultimate and rugby are goverened by The Missouri State High School Activities Association (MSHSAA).
