UCLA freshman quarterback Dante Moore continued to find that life on the road in the Pac-12 is a step up in competition.

Moore threw three first-half interceptions and the No. 18-ranked Bruins were unable to get another Herculean performance from their defense Saturday in a 36-24 loss to No. 15 Oregon State at Reser Stadium in Corvallis, Ore.

UCLA (4-2, 1-2 Pac-12) generated just 169 of its 453 yards through the air, with Moore finishing 15 of 34 for 168 yards and a touchdown to go with the three turnovers and five sacks. He also struggled in similar fashion three weeks ago at Utah.

The Beavers (6-1, 3-1 Pac-12) racked up 415 yards, becoming the first team to eclipse 400 against the nation's best defense in yards per play allowed (3.74). OSU averaged 7.68 yards per play in the contest.

OSU quarterback DJ Uiagalelei finished 14 of 24 for 266 yards and two touchdowns. Tight end Jack Velling pulled in three catches for 83 yards and two scores.

UCLA trailed by as many as 19 early in the third quarter and head coach Chip Kelly turned to Kent State transfer quarterback Collin Schlee to open a series.

Schlee's strong legs and running prowess helped set up a 9-yard touchdown run from running back T.J. Harden to pull within 29-17 at the 7:07 mark.

After trading touchdowns, UCLA forced a punt with 10:08 left in the fourth. Facing fourth-and-8 on the Oregon State 16-yard line, Bruins right guard Josh Carlin and right tackle Garrett DiGiorgio were whistled for consecutive false starts to move the ball back 10 yards.

On the ensuing snap, Beavers linebacker Calvin Hart Jr. waited for an opening before coming in untouched to sack Moore and turn the ball over on downs with 5:45 remaining.

The Bruins' offense got off to another slow start, with Moore throwing a pair of first-quarter interceptions that contributed to a 13-0 deficit after the first 15 minutes. Kelly then started to mix in Schlee with Moore and found success.

Schlee ran the ball four times for 46 yards in the half, helping the Bruins pull within 13-10 on a Moore touchdown pass to Logan Loya and a field goal from R.J. Lopez past the midway point of the second.

Trailing 16-10 with 48 seconds left in the half, Moore then threw a pick-six — his third in as many games — as Oregon State defensive back Ryan Cooper Jr. stepped in for a 67-yard interception return for a touchdown to give the Beavers a 23-10 advantage at the half.

With Moore struggling, it was Schlee who gave the UCLA offense a chance when he was summoned into the game.

Midway through the third, Schlee opened a drive with the Bruins trailing 29-10. Schlee's key 28-yard run set up Harden's score to cut the deficit to 12.

Following the scoring drive, Schlee appeared to be injured and did not return to the game. His impact, however, cannot be understated in getting the Bruins going on offense.

The redshirt freshman continued his strong start to the season, tying linebacker Oluwafemi Oladejo with eight tackles and a team-leading 1 1/2 for a loss.

Oregon State, however, kept UCLA's defense on the field for nearly 30 minutes after going 5 of 12 on third downs and converting its lone fourth-down opportunity. The Bruins entered the game allowing just a 33% conversion rate on both.

It was Schlee’s big run.

He executed the zone-read, but it was his strength that allowed him to stay on his feet after initial contact and pull off the big gain.

The combination of a freshman quarterback and poor offensive line play continue to be an issue.

Oregon State scored 17 points off Moore's three first-half interceptions, with his decision-making still leaving much to be desired. Moore also continues to be under heavy pressure, with the decisions being to either take the sack or get rid of it while being hit.

Kelly appeared to be unhappy with Moore as the Bruins tried to rally late, but the two false start penalties prior to the sack on the second-to-last drive did not help matters, either.

It was also a rough performance for the defense, particularly against Velling. Miscommunication on coverages led to chunk plays that the Bruins had done a good job defending against coming into the game.
