LAS VEGAS (Interstat) — In a stunning upset that defied both recent history and pregame projections, the San Jose State Spartans upended the Boise State Broncos 84-74 in a Mountain West Conference tournament game Wednesday night at T-Mobile Arena.

The victory, fueled by a balanced offensive attack and a resilient second-half performance, ended San Jose State’s season at 9-23 and sent the 20-12 Broncos, who were heavy favorites, to an unexpected early exit. Boise State had been installed as a 15.5-point favorite, and statistical models gave them a near 95 percent chance to win, especially after defeating the Spartans by 31 and 15 points in their two regular-season meetings.

The game’s most critical sequence unfolded late in the second half, transforming a tight contest into a decisive Spartan advantage. With just over nine minutes remaining and San Jose State leading 58-56, the Spartans unleashed a devastating 10-0 run in a span of just 90 seconds. The burst began with a Melvin Bell dunk off a Colby Garland assist, continued with a Sadraque NgaNga three-pointer, and was capped by another three-pointer from Jermaine Washington. That flurry pushed the lead to 68-56 with 8:30 to play, and the Spartans never allowed Boise State to get closer than six points the rest of the way.

San Jose State, which led 41-39 at halftime, showed remarkable poise in maintaining its lead despite the best efforts of Boise State’s Javan Buchanan. The Broncos’ standout forward from Lafayette, Indiana, scored a game-high 28 points, but the Spartans countered with multiple contributors. Garland, a guard from Magnolia, Arkansas, led San Jose State with 22 points, while Washington, from Hemet, California, added 18 points and six assists. NgaNga, a 6-foot-10 forward from Luanda, Angola, provided a crucial interior presence with 14 points and two blocks.

The Spartans also received key performances from Adrian Myers, who scored 14 points, and Bell, who chipped in 11. For Boise State, Andrew Meadow of Santa Clarita, California, scored 17 points, and Drew Fielder of Boise, Idaho, added 12.

The game was a stark reversal from the teams’ two regular-season matchups, where Boise State’s offense overwhelmed San Jose State. This time, the Spartans controlled the tempo and executed efficiently down the stretch, scoring 43 second-half points to Boise State’s 35. The total score of 158 points went over the pregame over/under line of 147.

The loss is a significant blow to Boise State’s postseason aspirations, while San Jose State concludes a difficult season on a triumphant note, having snapped a three-game losing streak with its first win in the conference tournament. An announced crowd of 2,351 at the neutral site witnessed the upset.

The Broncos finish their season with a 20-12 record, their hopes for an automatic NCAA Tournament bid extinguished. San Jose State’s season is complete.
