WACO, Texas — Zac Robinson completed 23 of 27 passes for 250 yards with three touchdowns and No. 14 Oklahoma State stretched its winning streak to five games with a 34-7 victory over Baylor on Saturday.

The Cowboys (6-1, 3-0 Big 12), who have won their last four games without injured running back Kendall Hunter or suspended receiver Dez Bryant, led 10-0 after their first two possessions. They made it 24-0 on Robinson's 19-yard TD to Cooper Bassett that capped an 87-yard drive to open the second half.

Baylor (3-4, 0-3), which has a 20-game losing streak to ranked teams, has scored only 24 points in its Big 12 games. The Bears are 1-3 since standout sophomore quarterback Robert Griffin tore a ligament in his right knee a month ago.

Oklahoma State, which plays No. 3 Texas at home next weekend, was again just fine without its top running back and top receiver from last season.

Robinson's 85-percent completion percentage was the best-ever for an Oklahoma State quarterback with at least 20 attempts, breaking the record his coach, Mike Gundy, set by hitting 27 of 35 passes (77 percent) against Kansas in 1989.

Bobby Reid was 9-of-10 in a game against Baylor three years ago.

Keith Toston ran for 109 yards and a 1-yard TD on his 15 carries, and Beau Johnson added 93 yards on 22 carries.

David Gettis' 17-yard touchdown catch with 7:17 left kept Oklahoma State from getting its first shutout in a Big 12 game since 2001.

Hunter, who has been out with a nagging ankle-foot injury, took part in pregame warmups but stayed on the sideline without a helmet once the game started, his fifth in row without playing. Bryant missed his fourth game since it was discovered he lied to the NCAA about an offseason meeting with former NFL player Deion Sanders. Bryant has asked the NCAA to reinstate him.

The Cowboys led 10-0 after the 22-yard TD catch by Wilson Youman, who grabbed the ball with both hands and bobbled it briefly before pulling it in and holding on when he was popped by safety Jordan Lake.

On Dameron Fooks' 16-yard TD catch that provided a 17-0 halftime lead, he leaped to make the catch between two defenders and held on despite being propelled into a mid-air spin before hitting the ground.

Hubert Anyiam, a week after 10 catches for 119 yards while filling in for Bryant, had nine catches for 83 yards including a pair of first-down grabs on Oklahoma State's first touchdown drive.

Toston had runs of 24 and 16 on the Cowboys' opening drive, when they settled for Dan Bailey's 24-yard field goal.

Baylor, wearing all-gold uniforms for homecoming, was then in good shape after Terrance Williams returned the ensuing kickoff 44 yards. But freshman Nick Florence, who started instead of senior Blake Szymanski, threw an interception on the next play.

Florence finished 20-of-34 passing for 230 yards.

Things don't get any easier for the Bears, whose next three games are against Nebraska, Missouri and Texas — a trio they are a combined 1-26 against in Big 12 play.
