BOISE, Idaho — Kellen Moore threw for 285 yards and three touchdowns, including a pair to Austin Pettis, to lead No. 5 Boise State to a 34-16 victory over UC Davis on Saturday night.

The Broncos (5-0) got off to a slow start and struggled to run the ball against the FCS Aggies.

The Broncos rushed for just 101 yards, far below the 214 yards per game they were averaging. Boise State got just 13 points in four trips to the red zone in the first half before Moore finally helped the offense get on track in the second half.

Moore was 22 of 31 with one interception. His longest TD pass was 42 yards to Titus Young. Pettis had 10 catches for 129 yards, while Young had six catches for 83 yards.

The Aggies (1-3) were led by quarterback Greg Denham, who was 24-of-36 for 206 yards and two touchdowns. Both of Denham's touchdowns came in the second half as the Aggies fought to keep pace. Midway through the third quarter, Denham fired a 21-yard TD to Sean Creadick to pull within 20-10. Then Denham connected with Creadick again on a 4-yard TD early in the fourth to cut the Broncos' lead to 27-16. The Aggies missed the ensuing extra point.

The Broncos defense held the Aggies to just 28 yards rushing. But the Broncos were penalized nine times for 61 yards, and the defense failed to force a turnover.

Moore's first TD came in the final minutes of the second quarter when he floated a 6-yard pass to Pettis in the left corner of the end zone, putting Boise State up 13-0 at the half.

After the Aggies turned Moore's interception in the third quarter into a 48-yard field goal by Sean Kelley, Moore led the Broncos quickly back down the field. Moore capped a three-play, 60-yard scoring drive by tossing a 42-yard TD to Young streaking down the middle of the field to go up 20-3.

The Aggies answered, scoring five plays later on Denham's first TD pass to Creadick.

The Broncos responded again through the air when Moore threw a 2-yard TD pass to Pettis to stretch their lead to 27-10 with 3:33 left in the third quarter.
