Gonzaga and Saint Mary's in the WCC final has become an annual tradition. The conference's top two teams have met in the title game seven of the past nine years, with the Zags winning six titles, including the past four.
Gonzaga won the two regular-season meetings this year fairly easily, beating the Gaels 79-56 in Spokane, 74-64 in Moraga.

The Gaels didn't have the same shooting touch against Gonzaga's smothering defense, needing nearly 11 minutes just to crack double figures scoring.

Gonzaga turned the missed shots and turnovers into baskets in transition, using a 12-0 run to build a 39-18 halftime lead.
The Gaels were better to start the second, shutting the Zags down while trimming the lead to 51-46 midway through.
They got no closer. Landale had to leave after picking up his fourth foul and Gonzaga took advantage, stretching the lead back to double digits.
Gonzaga will likely contend for No. 1 in the NCAA Tournament's West Regional with the Pac-12 Tournament winner.
Saint Mary's should have a good enough resume to make the NCAA Tournament despite the loss, but could have some anxious moments on selection Sunday after being left out last season.
