The victory was the first road win for coach Norm Chow at Hawaii (3-8, 2-4 Mountain West). The Warriors last win on the road was at Idaho in October 2011. It was Hawaii's first shutout win since a 2005 win, also at Idaho.
Tyler Hadden kicked a 36-yard field goal in the second quarter and added a 32-yarder in the fourth. Joey Iosefa scored from the 1 for the game's only touchdown with 18 seconds left in the first half, but was called for holding to nullify a second touchdown.
San Jose State (3-7, 2-4) almost doubled Hawaii's total yards on offense (462-240) and had a 24-11 edge in first downs, but the Spartans could not score, missing three field goal attempts, dropping a pass in the end zone and having a second intercepted in the end zone.
San Jose State converted 12 of 19 third down attempts, but was just 1 of 4 on fourth down and fumbled twice.
Gray drove to the Hawaii 2 midway through the second quarter, but on second and goal at the Hawaii 3-yard line, his pass was intercepted by Daniel Lewis Jr., who returned it to the Hawaii 20, where a penalty for an illegal block gave the Warriors a first down at the 10.
The Warriors then mounted a 14-play, 90-yard drive that took almost seven minutes to close out the first half. Iosefa carried 10 times on the drive, capping it with a 1-yard plunge for the touchdown.
San Jose State's Austin Lopez missed field goal attempts of 41 and 36 yards in the first half.
