BOISE, Idaho (AP) Derrick Marks scored 26 of his 28 points in the second half and made the go-ahead 3-pointer as Boise State defeated Colorado State 82-78 on Wednesday.

Colorado State led 73-68 when coach Larry Eustachy was called for a technical foul with 2:28 left for disputing a call. Marks made both foul shots, Rob Heyer's layup made it a one-point margin and Marks drained the go-ahead 3-pointer.
The momentum remained with Boise State down the stretch and Marks was 5 of 6 from the free-throw line over the final 40 seconds to seal it.
The Broncos were down by double digits in the second half but stayed in range of the Rams with their long-range marksmanship.

Bejarano hit a 3-pointer to increase Colorado State's lead to 73-68 with 3:13 left but Avila was called off an offensive foul and Eustachy's technical fueled Boise State's late-game charge.
In the first half, Thompson scored nine points over the first four-plus minutes to help Boise State take an 11-3 lead. The Rams bounced back with a 10-2 burst, capped by 3-pointers from Kidd and John Gillon, to tie it at 13 with 11:39 left in the half.
Colorado State trailed by five later in the half before Bejarano scored nine points during an 11-0 run as the Rams took a 28-22 advantage with 5:24 remaining.
