EUGENE, Ore. (Interstat) — A familiar rivalry takes center stage Sunday evening in the NCAA Division I Baseball Championship when Oregon State meets Washington State at PK Park. The Beavers (44-13) are the higher seed and carry momentum into the postseason after a 9-2 win over Yale on Saturday. Washington State (31-27) is coming off a 4-0 loss to Oregon and will need to rebound quickly.

The pitching matchup features two aces who have dominated at times this season. Oregon State right-hander Eric Segura is scheduled to start after a dazzling outing against Yale on May 30: 6⅔ innings, no hits, one earned run and 10 strikeouts. That performance followed a rough start against Air Force on May 15 (3⅓ IP, 7 H, 4 ER) and a gem at Long Beach State on May 9 (5 IP, 0 H, 1 ER, 7 K). For Washington State, left-hander Luke Meyers will take the mound. He threw 7⅓ innings against Oregon on May 30, allowing five hits and one earned run while striking out seven. Meyers also had a dominant seven-inning, no-hit outing at San Diego State on May 23, though he yielded four earned runs in six innings at Air Force on May 10.

The teams have split their last three meetings, with Washington State winning 3-2 on Friday, May 29, and 7-6 on April 7, while Oregon State trounced the Cougars 18-0 in a seven-inning game on April 6. The Beavers have won nine of their last 10 games, including a series sweep at Long Beach State in early May. Washington State has gone 4-4 in its last eight, with two wins over Air Force and a series victory at San Diego State.

Oregon State’s offense has been potent. Shortstop Tyler Inge went 2-for-4 with three RBIs against Yale, and reliever Isaac Yeager threw 1⅓ scoreless innings. Washington State’s lineup struggled against Oregon, managing only one hit, but catcher Cam Macleod had a single. The Cougars will need to generate more run support for Meyers, who has a 1.80 ERA over his last two starts but has received only two runs of support.
