Femi Hollinger-Janzen scored midway through the first half and Indiana held off Creighton 1-0 on Friday night to advance to the NCAA soccer final.
The seven-time champion Hoosiers (15-5-3) will play Georgetown in the title game Sunday. The Hoyas beat Maryland 4-3 on penalty kicks following a 4-4 tie.
The Hoosiers have allowed only two goals in four NCAA tournament games.
"There's no doubt that strong team defense is the formula for having successful tournament runs and winning championships," Indiana coach Todd Yeagley said. "In the final 10 minutes, when Creighton was sending a lot of players forward, that's when you saw the resiliency in this team. And then that save by Luis was fantastic."
Hollinger-Janzen gathered a deflected crossing pass on the right wing and booted an 8-yard shot that bounced in off goalkeeper Jeff Gal for his fourth goal of the season. That was one of only three shots on goal for Indiana in the game.
"They had their one chance, and that's all they needed," Gal said. "In the end that's what it took for us to lose this game."
Hollinger-Janzen had another goal disallowed when it was ruled that the shot occurred just after the end of the first half.
Indiana's pressure defense frustrated Creighton (17-4-3) throughout the game. The Bluejays finished with only two shots on goal — both in the final 3 minutes.
"It was hard for us to move because they pressured so much," Creighton midfielder Jose Gomez said. "It was hard to find a rhythm."
The Bluejays' best scoring chance was taken by Brendan Hines-Ike, who blasted a shot from 25 yards out that goalkeeper Luis Soffner deflected with a leaping hand save.
"Luckily that was really the only thing I had to do all night," said Soffner, who has given up 18 goals in 23 games this season.
It was the first loss for Creighton in 15 games. The Bluejays had gone 12-0-2 after opening 5-3-1.
Indiana won its last title in 2004,
