SPRINGFIELD — To the extent that it's possible to dominate an overtime game, top-seeded Southern Oregon kept eighth-seeded The College of Idaho under its command Friday afternoon in the quarterfinal round of the Cascade Conference Championships.

Finally, with steady rain falling at the Willamalane Sports Complex, the Raiders got the goal they needed for a 1-0 victory in the 91st minute as Zac Hansen headed in Esteban Castaneda's cross just 44 seconds into the first overtime period.

Hansen's golden goal put the Raiders (12-6-1) in today's 4 p.m. semifinals. They'll play Northwest Christian.

SOU's nation-leading shutout total swelled to 11. The Raiders have held seven opponents scoreless during an eight-game unbeaten streak, but the Yotes (9-9) were the first opponent this year — and the first in 32 games dating back to last season — who failed to put a single shot on goal.

SOU accumulated an 18-7 advantage in total shots, and Yotes keeper Grant Billings saved the first five shots on goal he faced. C of I put a minor scare in the Raiders with eight seconds left in regulation when Bekir Cinac took a corner kick, but the resulting shot by Lucas Schlake was blocked and sent out of the box.

Hansen, a sophomore defender from Sacramento, has scored a goal in three of SOU's last four games — all on headers — with a pair of game-winners. Prior to this stretch, he went his his first 30 collegiate appearances without recording a point.

Castaneda's assist was his first of the season, and, with five goals, he's now tied for the team lead in points.

The postseason win was the first ever for the Raiders, who were eliminated in penalty kicks by Carroll (Mont.) in last year's quarterfinals. They also defeated C of I during the regular season, 2-1, on Sept. 17 in Caldwell.

Women's Soccer

SOUTHERN OREGON 1, CORBAN 1 (PK): At Springfield, the Southern Oregon women's soccer team's season was stopped in penalty kicks, an excruciating end to a 1-1 draw against Corban in the quarterfinal round of the Cascade Conference Championships.

By converting four shots in the shootout to SOU's three, the fourth-seeded Warriors (10-6-2) advanced to play sixth seeded Northwest (Wash.) in today's semifinal at the Willamalane Sports Complex. Top-seeded Eastern Oregon will take on seventh-seeded College of Idaho for the right to the other spot in Monday's championship match.

The scenario was a familiar one for the Raiders, who wrapped up at 10-7-1. They've gone to penalty kicks in the first round of the tournament three of the last four seasons and were eliminated in one such game by Corban in 2014. The Warriors have advanced through all five postseason matchups between the teams.

SOU took a 1-0 lead in the 69th minute, when sophomore Aislinn Waite took a ball that deflected off a defender and deposited it for her third goal of the season.

Raider keeper Hannah Ceciliani made three of her four saves in the second half but couldn't stop Holly Moorman from scoring the equalizer in the 84th minute via a through-ball. Emma Kosmala and Annouscka Kordom were credited with assists on the play.

In the shootout, Waite converted SOU's first attempt and Ceciliani stopped Corban's first. The Warriors made their next four, however — Lexi McQueary, Macy Goodwin, Heidi Fronk and Nadine Correa connected in succession — and keeper Sheyenne Brusven gave them the advantage by stopping the Raiders' second and third tries.

In the fourth and fifth rounds, Mia Volpatti and Makena Totushek scored their kicks to keep the Raiders alive. Correa then delivered the decisive blow.

The game was the last for seniors Jacqueline Laird and Kelsey Randall, who in four years helped the Raiders go 36-32-7 and were part of the team's first-ever conference title in 2016.

CORBAN 3, SOUTHERN OREGON 2: At Ashland, Southern Oregon did its best to postpone 10th-ranked Corban's celebration, but the Warriors erased a 2-0 sets deficit to clinch the outright Cascade Conference regular-season title and an automatic NAIA Championships bid with a 22-25, 14-25, 25-18, 25-13, 16-14 victory at Mountain Avenue Gym.

Warriors middle Alaina Gentili totaled 19 kills, and the senior All-American took over the match with 12 kills on 21 attacks and five blocks over the last three sets after the Raiders (15-9, 12-7 CCC) controlled the first two.

Corban (21-7, 16-3) scored the last seven points in a lopsided fourth frame, but SOU reclaimed the momentum in rushing out to an 11-7 lead on a Natalie James ace in the fifth. It was 13-10 in SOU's favor before the Warriors ran off four unanswered as Gentili put down a kill and Bethany Filipenko delivered three in a row. SOU right-side Taylor Ristvedt tied it at 14-all with a kill to stop the run.

Again, Filipenko capped a long rally with a kill, and on match point Adriana Aguayo smacked a ball down the line for the win. Filipenko finished with 12 kills on 15 attacks and no errors.

After winning six consecutive matches, the Raiders have lost back-to-back in five sets against ranked opponents. They'll go into the CCC Tournament with the No. 5 or 6 seed depending on the outcome of today's 5 p.m. match against Northwest Christian, and play in the first round Tuesday night at either 13th-ranked Eastern Oregon or 21st-ranked Northwest (Wash.).

With the top seed, Corban will host the semifinal and championship matches next Friday and Saturday in Salem.

The loss spoiled several outstanding individual performances, including Ristvedt's 16 kills, Malie Rube's 14, Ashlyn Flynn's 38 digs and Natalie James' 42 assists. Freshman middle Deziree McKee, filling in at middle for injured starting freshman Makayla Hoyt, performed admirably with eight kills on 15 attacks and seven of SOU's 10 blocks. Ariana Sattler assisted four blocks, and Emma Ryan added 12 digs.

For the Warriors, All-American outside hitter Amber Parker tallied 16 kills and 12 digs, Haley Wells had 22 digs and Madison Milligan went for 36 assists and nine digs. After attacking at an average of .111 over the first two sets, they hit .371 the rest of the way.

The CCC title marks their first since of the regular-season variety in team history.
