MACOMB, Ill. (AP) -- Jamaine Cook rushed for 113 yards and two touchdowns and Youngstown State held Western Illinois to 142 yards of offense en route to a 31-7 victory Saturday.
Cook eclipsed 100 yards for the 19th time in his career, and his two short touchdown runs gave him 38 career rushing TDs.
The Penguins (6-4, 3-4 Missouri Valley) also got rushing touchdowns from Kurt Hess and Torrian Pace while piling up 225 yards on the ground.
Western Illinois (3-7, 1-6), which lost its fifth straight, got its only points on a 1-yard run by Hayden Northern in the first quarter. That play was set up by a David McDaniel interception that put the ball on the Penguins' 17-yard-line.
The Leathernecks had just 52 yards rushing on 23 carries, and Northern was 10 of 18 passing for 90 yards.
Hess completed 14 of 22 passes for 147 yards for Youngstown State.
