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 was making his first career start in place of Higgins, who injured a shoulder last week.
