LAS VEGAS — Winston Shepard scored all of his 15 points during a second-half comeback and Skylar Spencer added 15 points to help San Diego State upset No. 14 California 72-58 in the Las Vegas Invitational on Thursday night.
Shepard scored nine straight points during a 14-0 run for the Aztecs (4-2) that cut Cal's lead to 45-44 early in the second half.
A long 3-pointer by Cal's Jordan Mathews ended the Bears' nearly 5-minute drought.
But then Cal (4-1) entered a 2 of 10 slump from the floor and the Aztecs took the lead. Spencer threw down a pair of one-handed monster slam dunks, and Shepard followed with an alley-oop lay-in to push San Diego State ahead 50-48 with 9:29 left.
Five Cal turnovers during a 6-minute stretch late in the game helped the Aztecs extend their lead to 58-50 with less than 5 minutes left.
The 15-point second-half deficit is the second-largest the Aztecs have overcome in a victory since 1996-97.
The Aztecs closed the first half just 1 of 19 from the field and trailed 36-28 at the break. San Diego State shot just 28.1 percent (9 of 32) in the first half and hit one field goal over the final 10:15 while connecting on 6 of 8 free throws.
The second half didn't start any better for the Aztecs. They missed three of their first four shots from the field while Cal opened on a 9-2 run for a 45-30 lead.
San Diego State ended up shooting 23 of 59 (39 percent). It marked the fifth consecutive game the Bears held their opponents to 40 percent or less from the floor.
Going into the game, Cal had outscored its opponents by an average of 85.2-64.2
Ivan Rabb scored a career-high 18 to lead the Bears.
California: The Bears went into the game outrebounding opponents by an average of 14.9 rebounds (44.2-29.3) but were outrebounded 44-36. Cal hadn't allowed an opponent to score more than 67 points in its first four games prior to San Diego State.
San Diego State: With the win, the Aztecs extended their winning streak against nonconference teams from the state of California to 43 games. San Diego State is now 7-6 against Top 25 teams since the start of the 2013-14 season. The Aztecs are on a 15-7 winning run against teams out of the Pac 12.
