Anthony Marshall scored a season-high 20 points, and Justin Hawkins and Khem Birch scored off rebounds on consecutive possessions in the final 1:18 to help UNLV upset No. 15 San Diego State 82-75 on Wednesday night.

Bryce Dejean-Jones scored 14 points and Birch had 12 for the Runnin' Rebels (15-3, 2-1 Mountain West Conference), who fell out of the AP Top 25 on Monday after losing at New Mexico and going to overtime against Air Force before winning.

The Runnin' Rebels outrebounded the Aztecs 43-31.

The Aztecs' loss left No. 19 New Mexico as the only team with a perfect league record at 3-0. The Lobos beat Boise State 79-74 in overtime.

Jamaal Franklin had a game-high 27 points while freshman Winston Shepard had 18 and Chase Tapley 16 for the Aztecs (14-3, 2-1).
