FORT COLLINS, Colo. (AP) Garrett Grayson threw four TD passes, breaking the school's single-season mark and Colorado State improved to 9-1 for the first time in 20 years with a 49-22 rout of Hawaii on Saturday night.
The Rams (5-1 Mountain West) were without Rashard Higgins, the nation's leading receiver, but they didn't need him to send the Rainbow Warriors (2-8, 1-4) to their 17th straight road loss.
Grayson threw for 278 yards and four touchdowns on 13-of-24 passing, and Charles Lovett had four catches for 134 yards and a TD.
Grayson, who played just one snap in the fourth quarter before taking the rest of the night off, entered the game with 22 TD throws.
He tied the school record he shared last year with Justin Holland (2005) when he hit Elroy Masters Jr. from 8 yards out. Masters, a redshirt freshman, was making his first career start in place of Higgins, who injured a shoulder last week in the Rams' win at San Jose State.
Grayson broke the school record with a 52-yarder to a wide-open Lovett later in the first quarter. He also hit tight end Steven Walker with a 30-yard TD throw as the Rams built a 28-8 halftime lead.
The Rainbow Warriors were held to a pair of field goals by Tyler Hadden in the first half and also got a safety, which was set up when Scott Harding's 32-yard punt was downed at the 2.
Hawaii's hopes of a second-half comeback were snuffed when receiver Harold Moleni coughed up the ball on the first play from scrimmage in the third quarter and free safety Kevin Pierre-Louis recovered at the Rainbow Warriors 22. Two plays later, Grayson threw a 16-yard TD pass to Xavier Williams for a 35-8 lead.
The Rainbow Warriors finally got into the end zone when Joey Iosefa, who returned to the lineup Saturday after serving a three-game suspension, scored from the 2 midway through the third quarter to make it 35-15.
The Rams responded with Dee Hart's 7-yard touchdown run that was set up by Lovett's 71-yard catch-and-run down the Rainbow Warriors' deflated sideline.
Colorado State also got two TD runs from Treyous Jarrells, from 9 yards out in the first half and 1 yard in the second.
Hart ran 11 times for 115 yards and Jarrells rushed 12 times for 69 yards.
Ikaika Woolsey was just 16 of 47 for 192 yards for Hawaii.
Hawaii hasn't beaten the Rams since 1992 and the Rainbow Warriors' last victory in Fort Collins was in 1988.
