LA GRANDE – Southern Oregon volleyball coach Josh Rohlfing picked up his 400th victory on Saturday to join an elite club. Few within it will be able to match his milestone story.

Rohlfing's Raiders went on the road and took down the top-ranked team in the NAIA, rival Eastern Oregon, in four sets at Quinn Coliseum. The only thing more shocking about the outcome was the relative ease with which it came to be in the 25-20, 14-25, 25-23, 25-17 decision.

Tossing aside EOU's second-set victory, the Raiders stormed out to leads of 17-11 in the first set, 19-11 in the third and 13-4 in the fourth. They fired on all cylinders behind Friley Curtiss' 17 kills and six blocks, Andressa Ribeiro Soares' 10 kills and eight digs, and outstanding performances from setters Annie Hite (23 assists, 8 digs) and Amanda Moffat (14 assists, 3 digs) that led them to a .243 attacking average – the highest for a Mountaineer opponent this season.

"The cool part about getting the 400th here is just putting a milestone on what this team has done to get to this point, to be able to go into a packed gym with so much poise and beat a team of that caliber," Rohlfing said. "It was one of those special nights when we got to see our team look so mature on the court, watching all those little things you talk about all year come together in one moment. They'll remember that for a long time."

SOU, which was a handful of points away from upsetting No. 19 College of Idaho a night earlier, has won five of its last seven to climb to 11-12 overall and 8-8 in the Cascade Conference. EOU dipped to 22-2 and 14-2.

The Mountaineers have won 38 of their last 41 home matches. The Raiders have been responsible for all three exceptions over the last two seasons.

They'd upset a top-ranked opponent once previously: on Aug. 19, 2011, when they knocked off preseason No. 1 Fresno Pacific. FPU went on to have a middling season; EOU has not.

Rohlfing, who took over at SOU in 2007, became the 21st active head coach in the NAIA to reach 400 wins. Among that group, his winning percentage of .731 is the eighth best.

His team's aggressive serving – led by Maelle Garon and Tais Vega, who had two aces apiece – set the tone. So did a defense at the net that got a match-high eight blocks from Tessa Zimmermann and compiled 13 total. EOU's top attacker, Keira Vaughn, totaled 10 errors compared to 12 kills.

After building their big lead in the third, the Raiders were in danger of watching the match swing the other way as EOU scored five straight points to tie it at 23-all. Ribeiro Soares put them back in front with a kill, and moments later Curtiss and Lanie Snow teamed up to block All-American middle Kiauna Mack and end the set.

The momentum continued into the fourth, where Hite served SOU to a 7-0 lead. EOU never got within five points of the Raiders the rest of the way.

"Eastern looked like the same team we played earlier in the year, I didn't feel like they let up or down, we just rose to the occasion," Rohlfing said. "Hopefully that gives us confidence to keep pushing through."

Ane Tuinauvai also came up big with nine kills on 16 attempts. She totaled five of those and added two blocks in the third set alone. Snow, meanwhile, assisted four blocks.

With four matches left in the regular season, the Raiders are alone in seventh place. They're home for the last time next week, facing Evergreen (Wash.) at 6 p.m. Friday and Northwest (Wash.) at 6 p.m. Saturday.
