NORMAN, Okla. (AP) —Jackson Arnold threw two touchdown passes and No. 15 Oklahoma held off Houston 16-12 on Saturday night.

The Sooners (2-0) struggled to move the ball and punted eight times. The Cougars (0-2) outgained Oklahoma 318-249 in total yards, including 260-174 in passing.

Oklahoma got a late interception from Robert Spears-Jennings to end one drive and a late safety from Gracen Halton to extend a slim lead.

"We did enough things wrong to deserve to lose," Oklahoma coach Brent Venables said. "We were fortunate to find a way to win. Overall, our body of work on offense was not very good today. I'm really proud of the guys that stepped up when they had an opportunity."

Arnold, a sophomore, completed 19 of 32 passes for 174 yards with an interception and rushed 11 times for 40 yards. He was sacked three times.

"A win is a win, no matter how ugly it was," Arnold said, "and believe me it was was ugly, but we'll take it."

Houston starter Donovan Smith rebounded from a poor performance against UNLV in a 27-7 home loss to complete 24 of 28 passes for 260 yards and a touchdown with an interception.

"I thought out guys played extremely hard, they were very competitive, from the beginning of the game to the end," Houston coach Willie Fritz said. "That was a big step forward. When you're playing the No. 15-ranked team in the country you've got to play smart though, too, and we made some mistakes at critical points of the game."

Oklahoma led 14-6 at the half. The Sooners punted on their first two possessions, but led 7-0 after converting a muffed punt by Houston's Mekhi Mews into points when Arnold found receiver Brenen Thompson for a 10-yard touchdown pass on the next play.

The offense got going on the next possession, driving 81 yards in eight plays. Arnold threw to tight end Jake Roberts for an 11-yard touchdown strike to make it 14-3. Houston's Joseph Kim kicked a 43-yard field goal as time expired to pull the Cougars closer.

Houston scored quickly on its first possession of the third quarter. Smith found Joseph Manjack behind the defense for a 44-yard touchdown pass to make it 14-12. The 2-point conversion failed.

A promising Oklahoma drive followed but fell short of the end zone when Arnold's pass intended for Deion Burks was intercepted by Jeremiah Wilson at the 7. It was Arnold's first pick and the team's first turnover of the season.

FIELD POSITION
Venables praised punter Luke Elzinga, who dropped two of his eight punts inside the 5-yard line and three inside the 10-yard line.

"That was a big part of the game in a field position game," Venables said.

SECRET WEAPON
Oklahoma has thrown as many touchdowns to tight ends in its first two games as all of last year. Arnold threw a scoring pass to Bauer Sharp in a 51-3 win against Temple and found Jake Roberts for an 11-yard TD on Saturday.
