LUBBOCK, Texas, Nov. 3 (UPI) -- A six-yard touchdown run by Ricky Williams with two minutes remaining Saturday clinched the biggest victory for Texas Tech coach Mike Leach in his two years at the school -- a 12-0 blanking of No. 17 Texas A&M.
Texas A&M (7-2, 4-2 Big 12 South) began the day in a three-way tie for first place in the division with Oklahoma and Texas, but the defeat likely ended the Aggies' hopes for a Bowl Championship Series appearance.
Texas Tech, meanwhile, took a step up in the Big 12 and could take an even bigger one later in the season when it hosts Oklahoma.
Robert Treece kicked field goals of 25 yards in the second quarter and 37 yards in the third period before Texas Tech (5-3, 3-3) put away the contest on the scoring run by Williams.
The Red Raiders recorded their first shutout since a 58-0 victory over Oklahoma State last November. Texas A&M was blanked for the first time since a 24-0 setback to Penn State in the 1999 Alamo Bowl.
Kliff Kingsbury completed 38 of 46 passes for 303 yards for the Red Raiders while Williams ran for 48 yards on 18 carries.
Texas Tech entered the game ranked seventh nationally in passing efficiency.
Mark Farris connected on 22 of 31 passes for 206 yards for the Aggies, who were done in by a pair of turnovers in Texas Tech territory.
Texas A&M leads the all-time series, 33-26-1, but Texas Tech has a 4-2 edge since the creation of the Big 12 in 1996.
