The Seahawks play top-seeded LSU at 1 p.m Sunday and must beat the Tigers twice to advance to Super Regional play.
After Tulane scored a run in the top of the tenth, Brad Denson doubled to lead off the bottom of the inning and scored on a RBI single by left-fielder Chip Grawey.
Grawey advanced to second on Matt Wright's sacrifice bunt, and Tulane coach Rick Jones then decided to intentionally walk Jamie Hemingway before inserting closer Joey Charron.
Matt Sutton took Charron's first pitch into right field scoring Grawey to give the Seahawks the victory.
After seeing nothing but fastballs from Friday's match up with Charron, Sutton knew what was coming.
"Coach told me to sit on the fastball," Sutton said. "That's what he threw and I jumped on it."
UNC-Wilmington head coach Mark Scalf was very happy for his team after the Seahawks advanced to their first championship game in an NCAA regional.
"I can't say enough about this team," Scalf said. "I'm so happy for them. We have a tough road ahead of us tomorrow and we're going to give it are all."
Having to beat LSU twice on Sunday, Scalf said he will be creative with his pitching staff.
"I'm hoping for two no-hitters," Scalf said. "We're going to go with Chris Coughlin in the first game. He's started a lot of games for us this year, and he's our freshest starter as anyone can be at this point of the season.
"After that is Johnny Wholestaff."
