Freshman Tommy Edman hit a two-run homer in the bottom of the ninth inning Monday to lift Stanford to a 5-4 win over host Indiana, the No. 4 national seed, in the championship game of the NCAA's Bloomington Regional.
Stanford (34-24) will play at Vanderbilt (47-18) in the best-of-three super regional beginning Friday or Saturday.
"It was a fantastic win for us," said Stanford coach Mark Marquess. "Very proud of our team the way we battled back, and we beat an outstanding team."
Wayne Taylor started the ninth with a single through the middle, and pinch runner Drew Jackson moved to second on Brett Michael Doran's bunt before Edman's blast.
Edman said he was "just trying to get on base, to be honest. Home run was the last thing I expected."
Freshman ace Cal Quantrill, who started and won Friday's regional opener, worked 21/3 innings in relief to get the win. He allowed one unearned run on four hits and struck out three on two days' rest.
Indiana's Nick Ramos broke a 3-3 tie with an infield single in the top of the eighth.
The Hoosiers (44-15) led 3-0 early, but Stanford answered with run-scoring singles by Alex Blandino and Zach Hoffpauir in the bottom of the third. Dominic Jose tied the game at 3 with a solo homer in the sixth.
The game was delayed by rain for 2 hours, 51 minutes in the third inning, and starting pitchers Logan James of Stanford and Brian Korte of Indiana did not return after the delay.
The Cardinal was 30-25 this season, 5-19 in Pac-12 play.
San Jose Giants
Ydwin Villegas hit a two-run homer, his first of the season, and Joe Biagini pitched six strong innings to lead the Giants to a 6-4 win over the host Inland Empire 66ers. Biagini (3-3) allowed two runs on four hits, striking out eight.
