Much like Alabama on Thursday night, Oregon didn't waste any time Saturday afternoon against Tennessee in an elimination game at the Women's College World Series.

The No. 11-seed Ducks' first batter, right fielder Samantha Pappas, hit a solo home run off Lady Vols' starting pitcher Ellen Renfroe on the second pitch of the game.

Oregon (45-17) added another run later in the first inning, giving the Ducks all they needed in a 3-1 victory over seventh-seeded Tennessee (52-14) at ASA Hall of Fame Stadium in Oklahoma City, Okla.

The loss ends the Lady Vols' season.

"We lost two very close ball games," co-head coach Ralph Weekly said. "Our kids gave it everything we had. We just couldn't hit in the clutch. We're hitting the ball pretty good in BP and hitting the ball pretty good yesterday, and that happens at times. It's really not anybody's fault. There was no lack of effort out there, and we just got beat both times."

It was Tennessee's fifth appearance at the WCWS in eight years, and the first since 2010.

The Lady Vols' only run against Oregon pitcher Jessica Moore came on a two-out RBI single by centerfielder Tory Lewis in the bottom of the second inning, which scored catcher Ashley Andrews. Andrews was one of four Lady Vols senior along with Shelby Burchell, Cat Hosfield and Holly Baker, who were apart of 190 wins during their Tennessee careers.

Moore pitched a complete game for the Ducks and held Tennessee to just four hits en route to her 33rd win of the season.

"I have to give credit to Oregon," Weekly said. "They had a great game plan, and their pitcher did well. We hit a lot of ground balls."

Ellen Renfroe pitched just two innings before her sister, Ivy Renfroe, replaced her in the top of the third. Ivy Renfroe allowed a run in the fourth inning, which turned out to be the last run of the game.
