Cody Kirk rushed for 184 yards and four touchdowns, and Tray Robinson added a career-best 154 yards and two TDs as Montana State remained in first place in the Big Sky Conference with a 54-13 trouncing of Idaho State on Saturday, spoiling first-year Bengals coach Mike Kramer's return to Bobcat Stadium.

Kirk scored on runs of 2, 1, 72 and 1 yards, and Robinson cashed in from 1 and 34 yards as the Bobcats (8-1 overall, 6-0 Big Sky) rolled to a 37-6 halftime lead and then scored two quick touchdowns in the third quarter before substituting liberally. Elvis Akpla caught a touchdown pass for the eighth consecutive game, a 23-yarder with 8:26 to play in the third quarter to give Montana State a 51-6 lead.

Idaho State fell to 2-7 on the year, including 1-5 in Big Sky play.
