The Aztecs, who are off to the first 9-0 start in school history, outscored Cal 49-31 in the second half. As good as the Aztecs were offensively, their defense was even more impressive.

The Bears (5-3) shot 18 for 49 (36.7 percent) from the field, including 0 for 9 on 3-pointers, and made one field goal in the final 4:57. California entered the game shooting 43.2 percent from the floor this season.

San Diego State is fast gaining a reputation as a second-half team; the Aztecs entered the game outscoring teams by a combined two points in the first half, but 201-139 in the second half.

True to form, San Diego State led 28-26 at halftime against the Bears, who were playing the first of five straight home games before starting Pac-10 play Jan. 2 at Stanford.
