BOISE, Idaho- Robert Arnold scored 16 points and La'Shard Anderson added 13 to lead Boise State past Idaho 69-63, Saturday night at a near-capacity Taco Bell Arena.
Boise State (14-11, 7-6 Western Athletic Conference) completed a season sweep of the Vandals for the first time since the 2007-08 season. Idaho (14-11, 7-6), which upset No. 21 Utah State in Moscow on Wednesday, became the first road team to lose in the series in five games.
The Broncos trailed by five with 7:09 to play, but went on a 13-0 run to seize control of the game. Anderson scored 10 of the Broncos' points during the pivotal stretch.
The Vandals led 62-61 with 1:44 to play but the Bronco defense clamped down and Idaho did not hit another field goal. Boise State regained the lead and held on behind an 8-for-8 performance from the free-throw line in the final 90 seconds. The Broncos are 28-of-31 from the stripe in the last two games after shooting just 65.7 percent in their previous seven contests.
Paul Noonan knocked down four free throws in the final 32 seconds and Thomas Bropleh made it a four-point game with two of his own at the 21-second mark. Bropleh also hit a pair of 3-pointers in the second half, the first breaking a tie and the second giving Boise State a one-point lead with 6:26 to play.
An Arnold 3-pointer with 10 seconds remaining in the first half gave the Broncos a 36-33 lead at the break.
Jeff Ledbetter led Idaho with 19 points, including 6-of-8 from 3-point range, while Landon Tatum added 13.
The in-state rivals played in front of 12,193 fans, the largest attendance at a Boise State men's basketball game in at least the past 16 seasons.
