The CIF-Southern Section Baseball Tournament opens this week with 21 participating Catholic schools teams in the roles of spoilers rather than favorites.

Only four Catholic teams made the final regular-season CIF-SS divisional top-10 polls issued May 14. Alemany ranked ninth in Division 2; Cantwell-Sacred Heart, eighth in D-3; and Mary Star of the Sea and St. Joseph/Santa Maria, fifth and sixth in D-5.

Several early-season powerhouses fell on harder times as the year progressed, notably Notre Dame/Sherman Oaks, which was nationally ranked by Maxpreps back in February. The Knights ended 19-10, placing fourth in the Mission League and drawing a wild-card berth for its D-1 playoff opener May 16 against Moorpark.

No Catholic school played in the 2017 CIF-SS finals. The last Catholic school finalist was Cantwell-Sacred Heart in 2016 (D-5), and the last Catholic school champions were Santa Margarita (D-1) and Bishop Amat (D-3) in 2014.

A host of league champions made the 2018 tournament, including Bishop Amat (Del Rey), St. Bonaventure (Tri Valley), Cantwell-Sacred Heart (17-5, Camino Real), Bishop Diego (Frontier), St. Bernard (Santa Fe) and St. Monica Academy (Independence).
