Arizona quarterback Will Plummer is pressured by USC linebacker Drake Jackson during the second half of Saturday's game.

LOS ANGELES — With Khalil Tate watching from the sideline, Will Plummer darted through the USC defense for a 16-yard touchdown. Arizona pulled within 10 points of the Trojans. Could the Wildcats come all the way back, as they did in 2017 with Tate at the helm at the L.A. Memorial Coliseum?

They came awfully close. Arizona got within a score of USC. But as has happened so often during a losing streak that now sits at 20 games, the Wildcats couldn’t stick the landing.

The Cats lost to the Trojans 41-34 in front of an announced crowd of 52,435. Arizona (0-8, 0-5 Pac-12) remained one of two winless teams in FBS. USC (4-4, 3-3) won at home for the first time since Week 1 against San Jose State.

Arizona’s next chance to end the skid comes next Saturday against Cal. It won’t be easy; the Golden Bears upset Oregon State earlier in the day.

"Credit to our team. They battled their tails off," UA coach Jedd Fisch said. "It was 35-14 at halftime, and it came down to the very last play of the game.

"I made the reference last week about going from losing big to losing small to winning small to winning big. That was another great example of being there but not over the hump."

Plummer played well, authoring his best game as a Wildcat (20 of 34, 264 yards). Jamarye Joiner again had an impact as a quarterback before hurting his knee. None of it was enough to offset an Arizona defense that, for at least a half, reverted to its past form.

The Wildcats entered Saturday ranked fourth in the Pac-12 in total defense, yielding 362.4 yards per game. USC had 360 at halftime and finished with 547, the most by a UA opponent this season

USC quarterbacks Kedon Slovis and Jaxson Dart combined to complete 27 of 39 passes for 313 yards and four touchdowns.

The UA defense stiffened in the second half — when the Trojans played without star receiver Drake London — limiting USC to six points. But a 21-point halftime deficit proved too steep to overcome.

"We're putting a new offense in, a new defense, a new special teams and a new culture. It's a lot," Fisch said. "I’m proud of the way these guys battled, and I hope this second half is the start of something really special."

Four years ago, Tate led Arizona back from a 35-6 deficit. The Wildcats tied the score at 35 with 8:23 to play. They ultimately lost 49-35, ending a four-game winning streak.

Arizona trailed this one 35-14 at halftime. But the Wildcats got the ball to start the second half, and they advanced into scoring range.

Arizona appeared to move into the red zone on the latest of several trick plays drawn up by Fisch and his staff. With Joiner in the shotgun, Plummer went in motion and took a handoff. He then threw a backward pass to Joiner, who connected with Stanley Berryhill III for a 10-yard gain to the USC 16. But Arizona was flagged for an illegal formation, negating the play.

A sack on third-and-11 forced a field-goal attempt. Lucas Havrisik missed wide left from 51 yards.

The Wildcats kept battling. Linebacker Anthony Pandy intercepted Slovis on the next possession and returned the ball 37 yards for a touchdown. It was Arizona’s first pick-six since it had two against Cal on Oct. 6, 2018.

"It felt really good being in my hometown, at the Coliseum," said Pandy, who finished with nine tackles. "A lot of my family is here. So it was good that I made a play and they all saw it."

Pandy’s play also enabled the Wildcats to end at least one streak. They had failed to score 20 points in 10 consecutive games. The pick-six and Tyler Loop’s PAT put them at 21.

Arizona wasn’t done. Plummer capped a nine-play, 60-yard drive with the aforementioned 16-yard TD scamper. That made it 38-28 with 12:50 left in the fourth quarter.

After a second straight defensive stop, Arizona advanced to the USC 8. Three incomplete passes forced a field-goal attempt. Tyler Loop’s 25-yarder made it a seven-point game with 6:04 left.

The Trojans responded with a five-play, 52-yard drive that culminated in a field goal. The key play: Keaontay Ingram’s 45-yard rush. He finished with 204 yards.

Arizona drove for another field goal by Loop, a 40-yarder with 1:26 left. The Wildcats couldn’t recover the onside kick.

"We made a huge point of emphasis (of) what the fourth quarter should look like, how you compete all the way through the fourth quarter," said Fisch, whose team had been outscored 48-0 in the fourth period in Pac-12 play. "I think we all saw that there was absolutely no flinch, no letdown, no anything."

London and his teammates had their way with a depleted Arizona secondary in the first half. London caught nine passes for 81 yards and two touchdowns before exiting late in the second quarter. His right leg got caught underneath cornerback Christian Roland-Wallace after a 6-yard TD catch. London, a projected top-10 draft pick, had to be carted off.

Fisch and his staff threw several wrinkles at the Trojans — including playing Joiner as a traditional quarterback. With Arizona trailing 7-0 in the first quarter, Joiner threw a 73-yard touchdown pass to Tayvian Cunningham. It was the Wildcats’ longest play since Cunningham’s 75-yard TD vs. USC in last year’s opener.

After Slovis threw a 62-yard touchdown pass to Gary Bryant to make it 14-7, Arizona pulled another trick out of its bag. In punt formation to start the second quarter, Pandy took a direct snap and ran 32 yards for a first down.

Arizona advanced to the USC 24-yard line, but a holding penalty and a sack halted the drive.

Kyle Ostendorp pinned the Trojans at their 4-yard line, but they marched 96 yards for a touchdown to make it 21-7 midway through the second quarter. London finished the drive with a 2-yard TD catch from Dart.

London’s second TD made it 28-7. Arizona answered with a touchdown, which was preceded by a near-touchdown. Plummer threw a long pass to Cunningham, who seemed to be on his way to a 72-yard TD. But Isaac Taylor-Stuart ripped off Cunningham’s helmet at the USC 37. By rule, the play had to be stopped there.

After a 24-yard pass from Plummer to Alex Lines, Michael Wiley scored from the 1 to make it 28-14 with 2:36 left in the half.

With Slovis back in at quarterback, the Trojans went 75 yards in just over two minutes. Slovis’ 15-yard TD pass to Bryant made it 35-14.

The Wildcats lost starting free safety Jaxen Turner to a targeting disqualification in the first quarter. Gunner Maldonado, who missed last week’s game because of a shoulder injury, initially replaced him but wasn’t healthy enough to continue. That left Arizona with backups Jaydin Young and Rhedi Short at the safety spots, and USC took full advantage.

That Arizona was able to counterpunch was an encouraging sign. The Wildcats' 466 yards were a season high.

"I thought we had the best week of practice we’ve had all season this past week," Plummer said. "Our offense looked really good. We made a lot of big plays in practice. It seemed like everybody just started to understand the offense. It was amazing to see.

"It seemed like something just clicked. I don't know what it was. But everybody was locked in. Everybody was ready to just come back to work, and it's showing."
