UCLA's offense picked up where it left off last week and practically was unstoppable on Saturday.

After the Bruins overcame a 34-point deficit in their opener on Sunday, quarterback Josh Rosen completed 22 of 25 pass attempts for 329 yards and five touchdowns to lead UCLA to 56-23 win over Hawaii on Saturday at the Rose Bowl in Pasadena, Calif.

In two games this season, Rosen has thrown for 820 yards and nine touchdowns. He was 12 of 14 in the first half as the Bruins (2-0) built a 35-7 advantage.

Rosen led UCLA on a 99-yard scoring drive in only seven plays on its first possession. On a play-action pass, Rosen threw a dart and found Darren Andrews open from 25 yards out and UCLA was off and running.

Hawaii drove 56 yards in eight plays setting up a field-goal attempt by Ryan Meskell. Meskell missed and the Bruins took over on Rainbow Warriors' 32-yard line.

Rosen made the Rainbow Warriors pay as he guided the Bruins 68 yards in seven plays and a 26-yard touchdown strike to Theo Howard for a 14-0 lead.

Hawaii (2-1) got on the board when quarterback Dru Brown found Diocemy Saint Juste from 4 yards out to make the score 14-7.

UCLA scored on its next two possessions to go up 28-7. Demetric Felton scored on a 1-yard run for the first score, and tight end Caleb Wilson completed a 39-yard pass to Nate Starks to set up the second. Rosen found Andrews over the middle from 9 yards out for the touchdown.

Freshman defensive back Darnay Holmes excited the home crowd at the Rose Bowl by making his first collegiate interception and returning it 30 yards for another UCLA touchdown and a 35-7 lead heading into halftime.

The Bruins scored on every possession except their final one of the half.

Rosen remained hot in the third quarter hooking up with Andrews on another scoring strike, this time from 34 yards.

UCLA scored 28 straight points until Brown and John Ursua hooked up for a 2-yard touchdown capping 13-play, 79-yard drive.

The win might have been a costly victory for the Bruins. Three starters on defense had to leave the game with injuries.

Linebacker Kenny Young, a second-team All-Pac 12 performer left, and safety Adarius Pickett, who had 11 tackles in the win over Texas A&M, left with a leg injury.

Jaleel Wadood, another safety, took a shot to the head and had to leave.
