Glasco Martin ran for three touchdowns, Lache Seastrunk had 185 yards rushing with an 80-yard score and Baylor again upset the BCS picture with a late-season victory, beating the Wildcats 52-24 Saturday night.
A week after the Wildcats (10-1, 7-1 Big 12) took over the No. 1 spot in the BCS standings following defending national champion Alabama's loss, it now looks like it's going to somebody else's turn at the top.
Maybe Notre Dame, which could get its championship shot after Kansas State and No. 1 Oregon both lost. And the Crimson Tide suddenly is back in the title picture, along with a couple other SEC teams.
Also, K-State quarterback Collin Klein may be a Heisman Trophy front-runner no more after throwing three interceptions and getting sacked twice while being pressured and harassed all night. He threw for 286 yards, but had only 39 yards on 17 carries.
On first-and-goal from the 6 in the fourth quarter, Klein had four straight carries and couldn't score -- twice trying from the 1.
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 (5-5, 2-5) 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 plenty of time for this loss to simmer. The Wildcats have 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.
That may be the only solace after such a crushing loss against Baylor.
Klein, who finished 27-of-50 passing, had thrown only three interceptions the first 10 games.
After Martin's 2-yard TD 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.
