Eric Mika had 29 points and 11 rebounds to help BYU upset No. 1 Gonzaga 79-71 Saturday, ending the Bulldogs' bid to go undefeated in the final game of the US men's college basketball regular season. Nigel Williams-Goss scored 19 points for Gonzaga (29-1, 17-1 West Coast Conference), which was seeking to become the first team since Kentucky in 2014-15 to finish the regular season without a loss. Mika's basket with a minute left gave BYU (21-10, 12-6) a 73-71 lead. Gonzaga lost the ball on its next two possessions, and Corbin Kaufusi had a putback and Mika hit two free throws to put it out of reach. The last team to finish the entire season undefeated was Indiana in 1975-76. UCLA 77, Arizona 72: Thomas Welsh scored 12 of his 14 points in the second half and No. 5 UCLA dominated the offensive boards to beat Arizona in a Pac-12 showdown. The Bruins (26-3, 13-3) snapped Arizona's 21-game home court winning streak and dropped the Wildcats (26-4, 15-2) into a tie with Oregon for first place in the Pac-12 heading into the final week of the regular season. Vollanova 79, Creighton 63: Eric Paschall scored a season-high 19 points and Josh Hart added 16 to help Villanova wrap up its fourth straight Big East regular-season title. Kansas 77, Texas 67: Josh Jackson scored 18 points and Frank Mason III added 16 to help Kansas beat Texas and win its 13th consecutive Big 12 regular-season championship outright. Oregon 75, Stanford 73: Jordan Bell scored on a putback with 14 seconds left to give Oregon a rare Bay Area sweep. Bell's game-winner followed Dillon Brooks' last-second, tiebreaking 3-pointer three nights earlier at California to give Oregon (26-4, 15-2 Pac-12) its second sweep of its conference Bay Area rivals since 1976. N. Carolina 85, Pittsburgh 67: Justin Jackson scored 23 points, Joel Berry added 19 and North Carolina continued its march to the Atlantic Coast Conference regular season title. The Tar Heels (25-5, 13-3) have won four straight following a loss to arch rival Duke two weeks ago. North Carolina can clinch its second straight ACC regular season crown and 31st overall with a win at No. 18 Virginia Monday. Iowa St. 72, Baylor 69: Deonte Burton scored 22 points, including a crucial 3 with 1:17 left, and Iowa State won its fifth straight. Kentucky 76, Florida 66: Malik Monk scored 30 of his 33 points in the second half and Bam Adebayo added 18 points with 15 rebounds as Kentucky took over the Southeastern Conference lead.
