MORAGA, Calif. — By forcing the ball out of Jock Landale’s hands, Gonzaga was able to avenge a home loss to Saint Mary’s and move back into first place in the West Coast Conference. Rui Hachimura scored 23 points and was a key part of a defensive effort that neutralized Landale as the 12th-ranked Bulldogs ended the nation’s longest active winning streak at 19 games with a 78-65 victory over the 11th ranked Gaels on Saturday night. Landale made 12 of 15 shots in Saint Mary’s win at Gonzaga last month but was held to just four shots and two baskets because of relentless double teams right from the start in the rematch, “When they came in our gym they stole one from us at home,” guard Josh Perkins said.
