Blackmon caught 10 passes for a career-best 207 yards, including a game-changing 62-yard touchdown reception from Brandon Weeden early in the third quarter. Texas Tech safety Cody Davis went for the interception but didn't get there in time as Blackmon leaped to catch the pass on the sideline in front of the Red Raider bench. The Cowboy receiver somehow managed to catch the ball and raced down the sideline untouched for the touchdown to give OSU a 31-14 lead.
The Weeden-to-Blackmon touchdown pass was set up when free safety Johnny Thomas forced a Barron Batch fumble that OSU defensive end Jamie Blatnick recovered at the Cowboy 36-yard line.
It was one of many big plays for the Cowboy defense.
Texas Tech entered the game with the nation's fourth-best passing offense (333.2 yards per game) but was limited to just 226 yards by the Cowboy defense, which more importantly did not allow a single point on three Red Raider drives into OSU territory.
The Cowboys stopped the Red Raiders on the Johnny Thomas forced fumble and Blatnick recovery at the 40 early in the third quarter.
Senior middle linebacker Orie Lemon had a career-high 17 tackles against the Red Raiders but one of the most important was midway through the fourth quarter. After Tech had driven from its own 31 to the OSU 4, Lemon and teammate Justin Gent stopped Red Raider running back Eric Stephens about a foot short of a first down on a fourth-and-1 play.
The defense also made a big play on Tech's next possession when cornerback Andrew McGee recovered another Stephens fumble after it appeared he'd picked up a first down inside the OSU 15-yard line on a fourth-and-10 play. The Cowboy offense then ran out the final 3:40 for the victory, and OSU's first win in Lubbock since Franklin Delano Roosevelt was President of the United States.
OSU dominated the first quarter of the game to take a 21-0 lead.
The defense forced Texas Tech into three-and-out possessions on its first three touches of the game, and Oklahoma State's offensive line paved the way for running backs Kendall Hunter (15 yards), Joseph Randle (1 yard) and Jeremy Smith (4 yards) to score touchdowns before the first quarter had concluded.
OSU was up 21-0 at the end of the first quarter and the Cowboys had out-gained the Red Raiders 215 yards to 38.
The only other years that Oklahoma State has begun a season 6-0 was 1945 (when the then-Aggies finished 9-0), in 1997 (when the Cowboys finished 8-4), and in 2008 (when they were 9-4).
Oklahoma State returns home next Saturday after two consecutive road games for homecoming and will host Nebraska in a nationally televised contest (ABC-TV) at 2:30 p.m..
