LAS VEGAS (AP) - Kelly Olynyk had 21 points and 12 rebounds, and top-ranked Gonzaga bolstered its case for a No. 1 seed in the NCAA tournament by routing Saint Mary's 65-51 in the West Coast Conference final Monday night. Already headed to the NCAA tournament for the 15th straight season, Gonzaga (31-2) sure had the look of a No. 1 seed, playing a superb game at both ends. The deep Zags shot 52 percent, dominated inside and teamed up to hound Gaels leading scorer Matthew Dellavedova everywhere he went. Elias Harris added 19 points for Gonzaga, which had a 42-18 in the paint. Saint Mary's (27-6) labored against Gonzaga's attacking defense, particularly after point guard Jorden Page injured his right knee midway through the first half. Dellavedova struggled for the second straight game, scoring two points on 1-of-8 shooting, and the Gaels went 7-for-27 from 3-point range.
