PROVO, Utah (AP) — Chase Fischer scored 19 points, Kyle Collinsworth added 17, and BYU knocked St. Mary's out of first place in the West Coast Conference, 70-59, on Thursday night.

With the loss, St. Mary's (18-3, 9-2 West Coast) falls a half-game back of Gonzaga (18-5, 10-2), which beat Loyola Marymount 92-63.

BYU (17-7, 8-3) remains in third place in the conference. Collinsworth had nine rebounds and seven assists.

St. Mary's led 37-33 at the half, but BYU opened a nine-point lead after a 13-2 run — punctuated by Fischer's 3-pointer — early in the second half.

BYU led by 13 points with 5:26 remaining, but Joe Rahon's 3-pointer trimmed St. Mary's deficit to six with 3:32 to go. The Gaels didn't score again, missing their last eight shots.
