SAN DIEGO -- The Mountain West Conference better watch out. Jimmer Fredette is getting over his strep throat and mononucleosis.
Fredette scored 33 points and helped key a 15-0 run midway through the second half that carried No. 14 BYU to a 71-69 win over San Diego State on Saturday night, the Cougars' 15th straight victory.
Fredette missed two games recently and played sparingly in others due to his illness.
"I felt good tonight," he said. "I feel like I'm getting back into good shape again. I'm not quite 100 percent, but I'm close. My energy level is still low. Some of my movements aren't as quick as usual."
SDSU certainly couldn't tell.
"We heard he was sick," guard D.J. Gay said. "He didn't look too sick. He had a hot hand. Hats off to him."
BYU (20-1, 5-0 Mountain West Conference) has the second-longest winning streak in the nation, behind Kentucky's 19 straight, and reached 20 wins for the fifth straight season.
The Cougars trailed 50-47 before going on their decisive run. Fredette, the Mountain West's leading scorer with a 19.4 average coming in, had five points, including a 3-pointer. Tyler Haws and Jonathan Tavernari also hit 3-pointers as the Cougars took a 60-50 lead with 6:11 to play.
SDSU pulled to 67-66 on Kawhi Leonard's jumper with 52.7 seconds left before Fredette made a layup with 19.9 seconds to go. BYU's Charles Abouo blocked Kelvin Davis' baseline shot with 4.6 seconds remaining. Davis fouled Fredette and he made two free throws to seal it.
"I felt like I wanted to be aggressive," Fredette said about making BYU's last basket. "I really wanted to take that last shot. I really like the ball in my hands. Even if they double-team me, I could be a facilitator."
Fredette "truly is one of the best," SDSU coach Steve Fisher said. "He knows how to create opportunities for himself -- he wiggles, he twists, he finds gaps, he can step back and make shots and he can shoot it on you when you are guarding him. He's very, very good.
"Sometimes you can fill a stat sheet and not be a guy that makes the plays to win, and Fredette did both," Fisher said.
Haws scored 17 for BYU.
Leonard, a freshman, had 16 points and 11 rebounds for SDSU (14-6, 3-3), his ninth double-double. D.J. Gay added 12 and Chase Tapley had 11.
Jimmer had 19 points in the first half, helping BYU to a 35-34 lead at the break.
The Cougars ran off to a 22-10 lead midway through the first half, getting eight points each from Jimmer and Haws.
SDSU scored the next seven points, including a 3-pointer by Chase Tapley, to pull to 22-17. Fredette hit two 3-pointers to extend BYU's lead to 30-21 before the Aztecs scored the next nine points to tie the game, including Tapley's 3-pointer with 2:29 to go.
SDSU got its first lead on Gay's 3-pointer a minute into the second half.
The Aztecs had won 14 in a row at home since a 10-point loss to BYU here last Feb. 24.
"It's huge to come in here and get a win," Fredette said. "Not many teams come in here and do that."
SDSU made only 7 of 22 attempts from 3-point range.
