LOGAN, Utah - As go the churning legs of running back Kapri Bibbs, so goes the fortunes of the CSU football team.
The Rams were 5-0 this season in games that Bibbs rushed for 100 yards or more. So when Bibbs was held to the second-lowest total this year, it wasn't going to pan out for Colorado State.
Joey DeMartino ran for 127 yards and a touchdown on a career-high 35 carries as Utah State pushed past CSU 13-0 Saturday afternoon.
Nick Diaz also kicked two field goals for the Aggies (7-4, 6-1 Mountain West). It was the first shutout for the USU defense since 2003.
Bibbs led the Rams (6-6, 4-3 MWC) with 54 yards on 18 carries. The only time Bibbs ran for less yards this season was when he was held to 12 yards by the stalwart defense of Alabama in Week 2.
Both teams combined for only 381 yards total offense.
In a game dominated by field position and defense, the teams combined for 17 punts. Aggie punter Jaron Bentrude had a career-high eight punts placed within the 20-yard line.
CSU quarterback Garret Grayson threw for 147 yards on 16-of-39 passing and was intercepted twice. Grayson was also sacked four times, all in the fourth quarter.
Diaz scored on field goals of 44 and 24 yards. A 33-yard attempt with 2:50 remaining in the game was blocked.
