BOISE, Idaho (AP) -Taylor Tharp threw a career-high four touchdown passes and Ian Johnson had 158 total yards and a touchdown to help Boise State roll to a 58-0 victory over New Mexico State Sunday night.
All four of Tharp's TDs came in the first half as the Broncos (4-1, 1-0 Western Athletic Conference) scored on five of their first six drives, building a 35-0 lead at the half.
But the win, Boise State's third straight, was a total team effort. Special teams blocked a pair of New Mexico State punts, one leading to Boise State's second score, a 25-yard screen pass from Tharp to receiver Jeremy Childs.
And the Broncos defense throttled the Aggies' (3-3, 0-1) potent passing attack, allowing just 64 total yards in the first half. New Mexico State came into the game with the nation's seventh-best passing attack, averaging 340 yards per game, but crossed midfield just once through the first three quarters.
Aggies quarterback Chase Holbrook, who was a game-time decision to play after injuring his ribs last week, started but was replaced by freshman J.J. McDermott in the second quarter. Holbrook was 4-of-8 for 32 yards and an interception.
McDermott struggled to engineer anything on offense the rest of the way, finishing 10-of-19 for 57 yards and two interceptions. Overall, the Aggies had just 89 total yards in offense, including minus-23 rushing.
Tharp left late in the third quarter with the game well in hand. He was 19-of-26 for 251 yards and he threw his touchdowns to three different receivers.
Childs, who caught six passes, caught the first when Tharp found him alone in the back of the end zone, capping a 10-play, 66-yard drive on their first possession. Then late in the first quarter, Tharp fired a 50-yard pass to Titus Young, putting Boise State up 21-0.
Tharp's final TD came with 8:22 left in the half, an 18-yard touchdown to tight end Ryan Putnam.
Johnson rushed for 85 yards on 17 carries, including a 6-yard TD late in the half to put the Broncos up 35-0. Johnson also caught four passes for 73 yards, including a 47-yard shovel pass that helped set up another touchdown that put Boise State up 45-0.
Overall, Boise State had 604 total yards, with 233 of that coming on the ground.
