BOISE, Idaho (AP) - Robert Arnold scored 26 points and Zack Moritz came off the bench to score 18 as Boise State eased past Eastern Washington 83-54, Wednesday night.
Boise State (4-0) is off to its best start since the 1998-99 season and its 29-point victory is the largest margin over Eastern Washington since a 40-point win during the 1987-88 season (92-52).
Laron Griffin led Eastern Washington (1-3) with 13 points, and Cliff Ederaine added 11.
With last season's Big Sky defensive player of the year, Glen Dean, sitting out with a bruised hand, the Eagles struggled to slow Boise State's fast-paced offensive attack.
Robert Arnold scored the game's first seven points and finished the first half with a game-high 15 points on a perfect 4-of-4 shooting, including 3-of-3 from 3-point range. He made each of his first six attempts from the floor, finishing with a season-high 26 points on 8-of-9 shooting. It was his second 20-plus-point game this season and the fifth of his career.
The Eagles stayed close early before Westly Perryman and Arnold sparked a 12-5 run late in the first half to give the Broncos a 43-27 halftime lead. The Broncos' 57.1 percent first-half shooting (16-of-28) was the best effort in the first period this season.
Moritz and Perryman led another 12-5 run to help the Broncos build a 55-33 lead midway through the second half.
Perryman finished with eight points and had a career-high four steals. He also added three assists. Moritz's 18 points were a career high, and it was just the third outing of his career with 10-plus points.
Paul Noonan chipped in 11, giving Boise State three players in double figures.
The Broncos finished shooting 29-of-55 from the floor for a season-high 52.7 percent.
The team will square off against Denver (1-4) at Taco Bell Arena, Saturday. Tip-off is scheduled for 7:05 p.m.
