David Klingler passed for 461 yards and five touchdowns, three to Manny Hazard, as ninth-ranked Houston breezed to a 44-17 victory yesterday over Southern Methodist in Irving, Tex.

The Cougars improved to 6-0 overall and 5-0 in the Southwest Conference. SMU is 1-4, 0-3.

Klingler, the nation's total offense leader, broke NCAA records with 76 attempts and 48 completions. The old records were 45 completions in 1982 by Northwestern's Sandy Schwab against Michigan and 73 attempts in 1989 by North Carolina State's Shane Montgomery against Duke.

Klingler threw touchdown passes of 17 and eight yards to John Brown in a 20-point first quarter, then hit Hazard on scoring passes of nine and seven yards in the second quarter and three yards early in the fourth.

It was the fifth time in six games that Klingler passed for more than 400 yards. He had 390 in the first half, which ended with Houston leading 34-7.

Klingler completed 17 of 29 passes for 184 yards, two touchdowns and a 20-0 lead in the first quarter alone. Houston was going into a stiff breeze, but the Cougars benefited from three fumbles and an interception.

Houston also set NCAA records with 52 plays, 32 completions and 48 pass attempts in the first half.

Texas 49, Arkansas 17: In Austin, Tex., quarterback Peter Gardere passed for a touchdown, ran for one and led four scoring drives as the 19th-ranked Longhorns beat the Razorbacks in a SWC game.

Texas (4-1 overall, 2-0 in the SWC) pulled away after Arkansas (2-4, 0-3) had closed to 20-17 on Quinn Grovey's second touchdown pass.

Grovey, second nationally in passing efficiency, threw touchdown passes of 33 yards to Tracy Caldwell in the first quarter and 78 yards to Derek Russell in the third.

Gardere passed 14 yards to Keith Cash for a first-quarter touchdown and scooted eight yards for a touchdown and 20-10 lead with 8:59 left in the third quarter. Both scores capped 80-yard drives.

The 49 points was the most for Texas against Arkansas since 1916.

Texas A&M 20, Baylor 20: In College Station, Tex., Michael Moore's 11-yard touchdown run and Jeff Ireland's extra point with 8:23 left gave the Bears a tie with the 25th-ranked Aggies (4-2-1, 1-1-1 SWC).

The Bears (3-3-1, 2-1-1) had a chance to win, but Layne Talbot hooked his 46-yard field goal attempt to the left with 1:39 to go.
