SALT LAKE CITY -- Tommy Grady threw for three touchdowns, Darrell Mack ran for 107 yards and Utah capitalized on a long list of mistakes by No. 11 UCLA in a 44-6 upset of the Bruins on Saturday.
Robert Johnson made two interceptions and forced a fumble at the 2-yard line, making what could have been a touchdown into one of five turnovers by UCLA (2-1).
The Bruins committed 10 penalties and unraveled in the second half as Utah (1-2) scored 30 straight points and beat them for the first time. Utah had been 0-8 against UCLA, which failed to score a touchdown for the first time in four years.
Louie Sakoda kicked three field goals, and Mack became the first Ute to rush for 100 yards since Quinton Ganther gained 120 in the 2005 Emerald Bowl against No. 24 Georgia Tech, which was also Utah's last win over a ranked team.
Mack ran for a touchdown and caught two TD passes in Utah's biggest offensive outburst this season.
UCLA's Ben Olson completed 20 of 40 passes for 290 yards and was intercepted three times.
The Bruins were shut out in the second half and went without a touchdown for the first time in a game since beating Illinois 6-3 on Sept. 13, 2003.
• Tulsa 55, Brigham Young 47 -- At Tulsa, Okla., senior Paul Smith passed for a career-high 454 yards and five touchdowns to lead the Golden Hurricane (2-0) to a wild victory.
The teams combined for 1,289 yards, including 1,027 through the air, in a game that hinged on four second-half takeaways -- two interceptions and two fumble recoveries -- by the Tulsa defense and two penalties on a late Cougars possession.
BYU (1-2) drove to a first down at the Tulsa 12 with about two minutes left. But consecutive false starts bumped the Cougars back to the 22, and quarterback Max Hall misfired on four consecutive passes from there.
Hall passed for a career-high 526 yards with four touchdowns and two interceptions.
