EUGENE, Ore. -- Continuing its best run of postseason success, Oregon (42-15) won its third consecutive NCAA Regional with a 4-1 win against Western Athletic Conference Tourney Champion BYU (45-15) on Saturday afternoon at Howe Field.

After a scoreless first four innings, the Ducks scored all four of their runs in the fifth inning, thanks to juniors Samantha Pappas and Kaylan Howard who each knocked in two runs with their double and homer, respectively.

Sophomore Alexa Peterson opened the inning with a walk, and junior Allie Burger beat out a bunt to the pitcher with one out. Pappas followed with her team-leading 16th double of the year to right-center field, and moved into a tie for second all-time for UO for two-baggers in a season.

The next pitch, Howard drilled her team-high 12th homer of the campiagn to center field -- seventh-most season-wise for Oregon.

BYU answered with a run in the bottom of the fifth, after J.C. Clayton lined an RBI single to right field after a pair of one-out walks.

In the circle for UO, junior Jessica Moore (30-12) struck out seven, walked two, scattered six hits, and her run allowed was earned.

Only the second Duck to ever post 30 wins in a season, the two-time All-Pac-12 pick also moved up the team’s career list in complete games (sixth, 60), and season charts in for appearances (third, 46), complete games (fifth, 29-tie) and innings (third, 265.2),

BYU starter Tori Almond (20-4), struck out eight, walked four, allowed five hits, and all four runs allowed were earned.

At the plate for the Cougars, six batters hit safely once.

Earlier in the tourney, UO defeated Portland State, 7-3, on Thursday, and the Cougars, 6-4, on Friday.

The Ducks are now 9-0 in regional play under third-year head coach Mike White, and look forward to their third-ever Super Regional bid.
