FRESNO, Calif. (AP) - Derek Carr passed for 452 yards and four touchdowns, two of them to Davante Adams, as Fresno State thrashed Air Force 48-15 on Saturday to capture a share of the Mountain West Conference championship.

Carr threw a 64-yard touchdown pass to Adams on the Bulldogs' second play from scrimmage and 1:46 later hooked up with Isaiah Burse for a 36-yard score. Fresno State led 21-0 after its first three possessions.

Marcel Jensen added two 1-yard touchdown catches, one from Carr and one from tailback Robbie Rouse for Fresno State.

The Bulldogs (9-3, 7-1) share the MWC title with San Diego State, which defeated Wyoming 42-28 on Saturday. Boise State can make it a three-way split by defeating Nevada next Saturday.

Cody Getz had 82 rushing yards and Jon Lee added 52 for Air Force (6-6, 5-3), which finished with 254 rushing yards and just 63 passing. The Falcons came in averaging 335.5 yards on the ground.

Besides his first career touchdown pass, Rouse finished with 106 rushing yards - the 21st time in his career he has surpassed 100 yards in a game. Burse had 158 receiving yards and Adams added 141 to increase his MWC-leading season total to 1,168.

Fresno State last won a conference title in 1999, when the Bulldogs shared the Western Athletic Conference championship with TCU and Hawaii.

It was the first meeting between Fresno State and Air Force since the 2000 Silicon Valley Bowl.

Air Force has already accepted an invitation to the Armed Forces Bowl on Dec. 29 in Dallas. Fresno State likely is bound for either the Hawaii or Las Vegas bowls.
