CORVALLIS, Ore. >> Elijah Hainline hit a three-run home run to spark a five-run second inning, and No. 15 national seed Oregon State pulled away to beat UC Irvine 11-6 on Monday, winning the rain-delayed Corvallis Regional and grabbing a spot in the super regionals.

“It’s tough coming out of the loser’s bracket on these deals,” UCI coach Ben Orloff said. “I think since the start of the regional era, it’s over 80% the team that wins it does so by winning the first two games and when you don’t do that, you’re in a bind.”

Oregon State (45-14) had to wait a day to advance after the game was suspended Sunday night with the Beavers leading 6-4 in the bottom of the fourth inning. Oregon State hits the road to take on No. 2 national seed Kentucky in the best-of-3 Lexington Super Regional this weekend.

Dub Gleed had a three-run home run to cap a four-run bottom of the first inning for UC Irvine (45-14) off Beavers starter Eric Segura.

Oregon State answered with a five-run second inning and never trailed again.

UC Irvine starter Nick Rincover left after issuing a leadoff walk to begin the big inning. David Utagawa took the mound and walked Wilson Weber. Hainline homered to center field to drive in three. Traves Bazzana added a sacrifice fly and Gavin Turley drove in the fifth run with a two-out double.

Mason Guerra had an RBI single and Dallas Macias drew a bases-loaded walk in the top of the fifth to put Oregon State ahead 8-5.

Gleed hit a solo shot in the bottom of the inning for the Anteaters’ final run.

“This is one of the best groups of guys that I’ve ever been a part of, best-coached team I’ve ever been a part of,” Gleed said. “All year we just try to grind out games. We know at times it’s not going to be perfect. We’re OK with that. We’re ready for whatever comes our way. We just fought as long as we could, unfortunately we came close but were just short.”

Micah McDowell drove in a run in the sixth with a two-out, bases-loaded infield single. Guerra hit a solo shot in the eighth and Macias hit the team’s 118th homer of the season — a two-run shot in the ninth.

Hainline, Guerra and Jabin Trosky bat 7-8-9 in the order, respectively. All three had two hits, combining for five RBIs and six runs scored.

Reliever AJ Hutcheson (4-2) was tabbed for the win. He retired all four batters he faced, striking out one.

Utagawa (3-1) did not retire a batter in taking the loss. He gave up four runs on two hits and two walks.

Oregon State beat the Anteaters 5-3 on Saturday.
