FORT COLLINS, Colo. (AP) Garrett Grayson threw for five touchdowns, pushing his career total to a school record 53, and Colorado State beat Wyoming 45-31 Saturday night for its sixth straight win.
It is the longest winning streak in a season for Colorado State since 2002, when the Rams also won six in a row.
Grayson completed his first 13 passes of the game and finished 18 of 21 for 390 yards passing. He had first-half scoring passes of 21 yards to Dee Hart, 65 yards to Joe Hansley and 43 yards to Rashard Higgins to help Colorado State (7-1, 3-1 Mountain West) race to a 24-3 halftime lead.
He finished off the Rams' opening drive of the second half with his fourth touchdown pass of the night, a 21-yard strike to Xavier Williams to top the previous mark by Moses Moreno, who threw for 51 touchdowns at Colorado State from 1994-97.
Higgins also had a 73-yard scoring reception from Grayson late in the third quarter, and he upped his touchdown catch total this year to 12, a single season Colorado State record. Dion Morton (2008) and Jeff Champine (1981) had shared the record with 10 touchdown catches.
The fastest Mountain West receiver to 1,000 yards this season, Higgins wound up with five catches for 174 yards to boost his total to date to 1,137.
Colby Kirkegaard completed 24 of 38 for 335 yards passing for Wyoming (3-5, 1-3), which lost its fourth straight. The Cowboys have lost back to back meetings with Colorado State after stringing together a four-year winning streak.
Trailing by 21 points at the half, Wyoming scored its first touchdown of the night on a 1-yard run by Brian Hill with 4:24 left in the third quarter to pull to 31-10.
But the Cowboys' defense showed its vulnerabilities again on the Rams' ensuing possession.
Grayson completed a short pass in the flat to Higgins and the fleet wide receiver outran Wyoming's secondary, sprinting down the left sideline untouched for the score.
Wyoming and Colorado State traded fourth quarter touchdowns. Hill had another 1-yard scoring run and Treyous Jarrells scored on a 6-yard run for the Rams before Kirkegaard threw 32 yards for a touchdown to Jalen Claiborne.
Kirkegaard added a 38-yard scoring pass to Tanner Gentry with 15 seconds left to play.
