WACO, Texas - Baylor used a 24-point third-quarter to break open a tight game, as the Bears earned their first win over a No. 1 team in school history with a 52-24 victory over Kansas State at Floyd Casey Stadium on Saturday night.

Wide receiver Glasco Martin ran for three touchdowns, running back Lache Seastrunk had 185 yards rushing with an 80-yard score and Baylor (5-5, 2-5 Big 12) moved within one win of bowl eligibility, while handing K-State (10-1, 7-1 Big 12) its first loss after it won its first 10 games of 2012. 

Senior quarterback Collin Klein became the first quarterback at a Bowl Championship Series (BCS) school to record 20 rushing touchdowns and 10 passing touchdowns in back-to-back seasons.  He threw 286 yards on 50 pass attempts, but did throw a career-high three interceptions while under constant pressure most of the night.

Nick Florence, the successor to Heisman winner Robert Griffin III, threw for 238 yards. Both of his touchdowns came in the first half when the Bears jumped out to a 28-7 lead.

It was on the same weekend last November, on another Saturday night in Waco, when Griffin and Baylor upset then fifth-ranked Oklahoma after two teams ahead of the Sooners had already lost that day.

Kansas State has Thanksgiving week off before playing their regular season finale Dec. 1 at home against No. 18 Texas.  If the Wildcats beat Texas, they will be guaranteed at least a share of the Big 12 title and get the league's automatic BCS spot.

Klein, who finished 27-of-50 passing, had thrown only three interceptions the first 10 games.

After Martin's 2-yard touchdown put Baylor up 28-7 with 2:54 left in the first half, Kansas State scored 10 consecutive points before the break - and then got the ball to start the second half, only to have Klein throw his second interception.

Martin finished with 113 yards rushing.

There was a classic 13-yard run by Klein to start the second half, then two deep incompletions before he was picked off by Sam Holl, who returned it to the Kansas State 38. Four plays later, after a Florence 13-yard keeper, Martin scored on a 4-yard run to make it 35-17.

The Wildcats then got a 50-yard kickoff return from Tramaine Thompson, but Klein had three consecutive incompletions leading to a punt that pinned Baylor at its 1.

Florence threw an interception, Randall Evans grabbing the ball at the 1 but immediately getting dragged down by intended receiver Terrance Williams. Klein plunged in from a yard out on the next play, but that would be the last score for the Wildcats.

On the first play after Klein was picked off in the end zone late in the third quarter, Seastrunk took a handoff and raced 80 yards for the score.

Chris Harper had 11 catches for 123 yards.
