Jimmer Fredette scored 25 points and Charles Abouo added 18 as No. 7 BYU spoiled the biggest game in No. 6 San Diego State's history, running away with an 80-67 victory Saturday to take a one-game lead in the Mountain West Conference.
The Cougars (27-2, 13-1) swept the season series against the Aztecs (27-2, 12-2). The second loss came in one of the most eagerly anticipated games in this city's history.
San Diego State's only lead was 2-0 on Kawhi Leonard's fallaway jumper after the Aztecs controlled the opening tipoff.
Fredette, who scored 43 points in BYU's 71-58 win over the Aztecs in Provo a month ago, helped the Cougars take control after San Diego State pulled to 47-44 on James Rahon's 3-pointer with just over 13 minutes to play.
Fredette made a 3-pointer and converted two three-point plays, and Jackson Emery made two 3-pointers as BYU took its biggest lead, 67-54 with 8:15 left.
