Gerald Landry threw two touchdown passes and DeWayne Bowden intercepted two passes -- one for a 62-yard touchdown -- as Houston capitalized on nine turnovers to upset No. 3 Texas, 29-15, yesterday in Austin, Tex.

Texas had won 18 consecutive Southwest Conference games and 24 straight regular-season games. The Longhorns (6-1-1, 4-1 conference) are just behind Texas Christian (5-1) in the conference. The two will play Saturday in Fort Worth; the winner will all but clinch a Cotton Bowl berth.

Texas had no turnovers and a 7-0 lead through the first quarter. Houston (5-4, 4-2) scored 17 points in the second quarter on a 79-yard pass from Landry to Anthony Ketchum, Mike Clendenen's 48-yard field goal and a seven-yard pass from Landry to Carl Hilton with nine seconds remaining.

Texas' only touchdown came on a two-yard run by Terry Orr after the recovery of Landry's first-possession fumble at the Cougars' 13.

Bowden intercepted Todd Dodge's pass in the end zone in the second quarter, and took a fourth-quarter deflection for a touchdown.

Before a fourth-quarter completion, Dodge, who had been closing in on Texas' passing record, was zero for 13 with four interceptions. He threw a fifth interception, tying a school record set 40 years ago. He finished two for 16 for 23 yards.
