Defeat Costs UCLA More Than a Game : Pacific 10: Arizona has no trouble with Bruins, 23-3. Ale sidelined for season. LaChapelle also injured.

Arizona, which came within two points of knocking off No. 2 Miami last week, ambushed No. 11 UCLA, 23-3, Saturday night before 50,608 fans at Arizona Stadium.

Besides being defeated, the Bruins lost linebacker Arnold Ale, their best defensive player, for the season because of a broken lower right leg and wide receiver Sean LaChapelle for an indefinite period because of a rib injury. The extent will be determined today.

Linebacker Bradley Craig was hospitalized for observation after sustaining possible internal injuries, and linebacker Shane Jasper will be sidelined for several weeks because of a sprained knee.

“Arizona totally dominated the game from start to finish,” UCLA Coach Terry Donahue said after the Wildcats held the Bruins to 36 yards rushing. “We obviously took a severe beating, both on the scoreboard and physically. We had several players that are seriously hurt. . . . We hope LaChapelle’s ribs aren’t broken.”

Ale was injured in the first quarter when he tried to tackle Arizona tailback Chuck Levy. Carried off the field, Ale was taken to a hospital for X-rays and he returned with a cast on his right leg.

LaChapelle, who surpassed Mike Sherrard to become UCLA’s all-time leading receiver, was hurt when he tried to make a downfield block for tailback Kevin Williams on the Bruins’ first play of the third quarter.

Quarterback Rob Walker, who had thrown one interception in his first 2 1/2 games, threw three interceptions and was sacked three times as the Bruins lost their Pacific 10 opener after beginning the season with nonconference victories over Cal State Fullerton, Brigham Young and San Diego State.

“They really didn’t surprise us,” Walker said. “They (rushed) seven or eight people all night. I had a whole lot of pressure, the most I’ve seen all year. It was just basic stuff. What can you say? They just ‘bull-rushed’ us.”

Walker, who completed 16 of 33 passes for 141 yards, said losing LaChapelle hampered the Bruin offense.

“It was a great loss. It hurt us immensely,” Walker said.

Arizona quarterback George Malauulu, a former Carson High player, completed 11 of 27 passes for 97 yards and one touchdown as Arizona improved its record to 2-2-1 overall, 1-1-1 in the Pac-10.

Kicker Steve McLaughlin, who had missed the potential winning field goal in last week’s 8-7 loss to Miami, was successful from 51, 45 yards and 34 yards against UCLA.

“McLaughlin’s performance was unbelievable,” Arizona Coach Dick Tomey said. “He went three for three right after a 50-yard field goal miss at Miami. His kicks went right up the middle.”

Leading, 10-0, at halftime, Arizona made it 13-0 when McLaughlin kicked a 45-yard field goal with 9:58 to play in the third quarter to cap a 14-play, 45-yard drive.

Strong safety Mike Scurlock recovered a fumble by Bruin running back Daron Washington to set up McLaughlin’s 34-yard field goal with 4:34 to play in the third quarter.

Linebacker Sean Harris intercepted a pass by Walker at the 38 and returned it five yards to set up a Ontiwuan Carter’s one-yard touchdown run with 5:13 to play in the fourth quarter.

As the crowd booed, Louis Perez hit an 18-yard field goal with 1:21 to play to extend UCLA’s NCAA-record scoring streak to 243 games. Arizona had stopped the Bruins at the one-yard line.

“We’ve got the longest scoring streak in the country going,” Donahue said. “The game was gone. Our players and coaches wanted to keep the scoring streak alive. Even though we got beat very badly tonight we have a lot of pride in our scoring streak.”

Arizona, which didn’t allow a first-half touchdown in its first four games, made it five by shutting out the Bruins in the first half to take a 10-0 lead. UCLA had only 43 yards in total offense in the first half.

Arizona’s defense, which limited Miami to two yards rushing in last week’s 8-7 loss, held the Bruins to one yard on the ground in the first half. UCLA, which didn’t have a first down in the first quarter, had only four in the first half.

Walker had played well in becoming the first Bruin quarterback to win his first two starts since Jeff Dankworth in 1974, but he looked like a redshirt freshman against Arizona’s aggressive defense, completing seven of 16 passes for 44 yards.

Walker, who had thrown only one interception and been sacked only once in 2 1/2 games since replacing Wayne Cook in the opener, was sacked twice in the first half and threw an interception to kill the Bruins’ best scoring opportunity.

After a pass interference penalty against Arizona defensive back Keshon Johnson gave the Bruins a first down at the Wildcat 25, Walker threw an interception to kill the drive.

Under constant pressure from the Wildcat rush, Walker completed only two of seven passes for 17 yards in the first quarter.

Arizona took a 10-0 lead when Malauulu threw a two-yard pass to tight end Roderick Lewis with 6:41 to play and Steve McLaughlin kicked a 50-yard field goal with 1:50 left in the opening quarter.

Malauulu, who completed seven of 10 passes for 57 yards in the first half, hit three consecutive passes for 29 yards as Arizona drove 58 yards in 11 plays. Malauulu hit Terry Vaughn with a 15-yard pass to give the Wildcats a first down at the Bruin two.

Malauulu found Lewis all alone in the end zone two plays later after a play-action fake to Levy, which froze the Bruin defense.

McLaughlin, who had blown a chance to beat Miami when he missed a 51-yard field goal attempt by two feet to the right as time expired last week, made a career-long 50-yard field goal on Arizona’s next series to cap a 28-yard drive to the UCLA 32.

Bruin Notes

It was the first time that UCLA had been shut out in the first half since 1989, when Arizona defeated the Bruins, 42-7, at Arizona Stadium. . . . UCLA wide receiver Sean LaChapelle, who went into the game needing two catches to pass Mike Sherrard and become the Bruins’ all-time leading receiver, had four catches for 29 yards in the first half. LaChapelle has 131 receptions for 1,938 yards. He needs 86 yards to break Flipper Anderson’s all-time receiving yardage record of 2,023 yards.
