LOS ANGELES -- In one of its most impressive wins ever, No. 8 Oregon (11-0) ended a 21-away match losing streak at No. 2 USC (13-1) Friday night to cap its opening week of Pac-12 play.

After losing twice at USC in five sets the last four years, UO held the upper hand with its 25-19, 25-15, 25-23 decision against the returning Pac-12 Champions, who had also beaten No. 1 UCLA earlier in the week at home.

"USC is always a good team that makes you raise your level and play your best," Oregon head coach Jim Moore said. "We didn't much differently than we had in past matches. That said, tonight was one win and we have a lot more matches ahead of us, so we can't get too excited."

The Oregon offense featured three hitters with +.300 hitting marks for the sixth time this year - senior outside hitter Alaina Bergsma (18 kills, .438), sophomore outside hitter Liz Brenner (16 kills, .577) and junior middle blocker Ariana Williams (8 kills, .375).

Brenner added a team-high two blocks and her nine digs left her just shy of her first double-double of the campaign.

Senior outside hitter Katherine Fischer added 12 kills and 12 digs for her third double-double of the season and 31st career-wise, and also tied for the team high in aces (1) with junior setter Lauren Plum.

Senior libero Haley Jacob made an impressive return to the starting lineup and racked up 21 digs - a season high by one over the team's previous best (20) in a five-set win at No. 24 Ohio State a month ago. The A2 National Team member also posted her 16th career 20-dig total (and second ever in a three-set match).

Plum ended with 46 assists, and directed the offense to a .357 combined hitting mark (compared with .189 for USC).

In other team comparisons, UO held notable edges in kills (55-32), assists (52-31), aces (2-1) and digs (57-37), while USC owned an advantage in blocks (8.0-4.0).On UO all-time lists, Bergsma joined Fischer on the career 1,000 kills list and now sports 1,001 - just behind Fischer's sixth-best total (1,016).

Plum also became the third Duck setter to connect on 3,000 assists and her 3,034 tally trails onlywith Nevena Djordjevic (4,400, 2006-09) and Stephanie Snyder (3,883, 1986-89).

"I was happy with how we served and passed, and I thought that would decide who won," Moore said. "Lauren was great at mixing it up and kept us in it in games one and two. In the third set, we got rattled a little, but then calmed down. Alaina helped us pull through that final set, and Kat had a big swing late to help seal it."
