Boise, Idaho ? Kellen Moore threw two touchdown passes and caught another on a trick play, helping No. 2 Boise State beat Louisiana Tech, 49-20, on Tuesday night for its 21st consecutive victory.

Boise State’s Titus Young (1) goes up for a pass against Louisiana Tech’s Josh Victorian (15). The pass was incomplete Tuesday in Boise, Idaho.

Moore was 20-of-28 for 298 yards while coolly directing the Broncos to 468 total yards. Tyler Shoemaker caught six passes for a career-high 124 yards and Doug Martin had 21 carries for a career-best 150 yards and two scores.

Moore threw a 6-yard touchdown pass in the first quarter to Austin Pettis, who snapped a three-game drought without a TD. He tossed a 32-yarder to Shoemaker in the second to give the Broncos a 21-7 lead.

Pettis returned the favor in the third when he took a pitch on an end around and quickly fired a 7-yard pass to Moore all alone in the right corner of the end zone.

The Broncos (7-0, 3-0 Western Athletic Conference) also got a big boost from Martin, who had a 2-yard run in the first that made it 7-0 and a 20-yard scamper in the fourth that wrapped up the scoring for Boise State.

Boise State needed another convincing win to keep pace in the BCS standings. The WAC powerhouse is No. 3 behind Auburn and Oregon.

The Broncos never trailed, building a 28-7 halftime lead thanks to Moore’s accurate passing and some miscues by Louisiana Tech (3-5, 2-2).

The Bulldogs used their hurry-up, spread offense to roll up 394 total yards against the nation’s top-ranked defense. But they hurt themselves with several costly penalties and mistakes.

Louisiana Tech had a chance to grab the momentum after a bold onside kick attempt in the first quarter following Lennon Creer’s tying 1-yard touchdown run. The Bulldogs caught the Broncos flat-footed and recovered the kick, but the play was nullified by an offside penalty. The call angered coach Sonny Dyke, who was flagged 15 yards, forcing Louisiana Tech to kick from the 13.
