OMAHA, Neb. -- Nathan Dettmer pitched three-hit ball over seven shutout innings, and Texas A&M capitalized on Notre Dame's mistakes to beat the Fighting Irish 5-1 in a Men's College World Series elimination game Tuesday.
Texas A&M (44-19), the No. 5 national seed, will play Oklahoma in the Bracket 1 final. The Aggies need to beat the Sooners on Wednesday and again Thursday to reach the CWS finals this weekend.
"This time last year we didn't even have a coaching staff,'' first-year coach Jim Schlossnagle said. "A third of this team wasn't even a Texas A&M Aggie yet. We were still recruiting out of the transfer portal. You look up a year later and you're playing in the final four of college baseball.''
Dettmer (6-3) was working on three days' rest after giving up seven runs and getting pulled in the second inning of Texas A&M's 13-8 loss to Oklahoma on Friday. He bounced back with his best performance of the season.
"I'm not going to lie to you. After Friday, I felt just terrible, like I let my team down,'' said Dettmer, who induced 10 groundouts. "But to come back and have Coach give me the ball just two games later, all that confidence just flowed through me and to know they trust me ... all I had to do was believe in myself. That's what happened and had some success today.''
Notre Dame reached base on an error and hit batter but didn't get their first hit until David LaManna singled with one out in the fourth.
Dettmer, who struck out six and walked none, had his longest outing since he went seven innings against Vanderbilt on April 28. He threw 99 pitches, 68 for strikes.
"They obviously didn't have fun with [Dettmer's sinker],'' Aggies third baseman Trevor Werner said. "It's fun to play behind that because you know you're going to get a lot of rollovers. We know when he's on, we're going to get a lot of plays. The whole team's feeling good when Dettmer's going.''
The Aggies converted two walks, a balk, two singles and a throwing error into three runs in the third, the first two off starter Liam Simon (2-1).
The Irish (41-17) ended the season with their most wins since 2006 and first Omaha appearance since 2002.
"Well, if there's a place you want to end it, it's obviously here,'' Notre Dame coach Link Jarrett said. "How we ended it was tough. That hurts. That wasn't indicative of how our team plays.''
Werner led off the fifth inning with a home run off Jack Findlay, and Dylan Rock later had an RBI single to make it 5-0.
Findlay, the Irish's star freshman left-hander, had allowed only one earned run over his 14⅓ innings in the NCAA tournament before giving up the two in the fifth.
Brad Rudis took over for Dettmer starting the eighth inning, and Brooks Coetzee drove Rudis' second pitch more than 400 feet over the left-field fence for his 12th homer. After Rudis walked the next batter, lefty Joseph Menefee came in for the Aggies and allowed one hit in two innings for his second save.
"We came in here to win the whole thing,'' Notre Dame's Jared Miller said. "This whole platform was special. We acknowledge that we ran through some tough teams. Maybe the outside didn't really give us a chance. But we wanted to win the whole thing. So it's tough right now.''
All nine games in the Men's College World Series this year have been decided by four or more runs -- a first in the event's 75-year history.
