NEW YORK — John Thompson led Georgetown to six Big East tournament titles, and its last appearance in the championship game. Now, his son has a chance to experience a conference final.

Jeff Green had a career-high 30 points, including the winning basket with 13 seconds left, and 12 rebounds to lead the ninth-ranked Hoyas to an 84-82 victory over No. 20 Notre Dame in the semifinals Friday night.

DaJuan Summers added 18 points and Patrick Ewing Jr. tied his career high of 15 to help top-seeded Georgetown (25-6) advance to the final for the first time since 1996 with its 14th win in 15 games.

"It is extremely rewarding to have the opportunity to play for the tournament championship," Hoyas coach John Thompson III said. "That's something that's special. Something that so few people get the opportunity to do is walk out on that floor tomorrow night and get a chance to play for the tournament championship."

Georgetown will face third-seeded Pittsburgh, which rallied to beat Louisville 65-59 in the other semifinal.

Green muscled his way through the lane for the go-ahead layup, before missing the ensuing free throw.

"Pat just threw it down and I went into my move and they fouled me and I got the lucky roll," Green said. "I jut put it up there and tried to get it on the rim and it went in. It was a lucky shot."

The Irish had a chance to win, but Russell Carter's 3-point shot with 6 seconds left bounced high off the rim. The Hoyas' Jon Wallace chased down the loose ball and heaved it high in the air toward midcourt.

Summers hugged Green near midcourt after the final buzzer and Thompson got a high-five and pat on the back from his father, who led the Hoyas to their six Big East titles from 1982-89.

"The performance Jeff Green put on today was special, and just our team in general hanging in there," Thompson said. "We could have caved on several occasions from the beginning of the game midway through the second half, and we fought, we hung in together.

"And then at the end of the day, great players make great plays and Jeff did that."

Carter had 21 points, including five 3s, and freshman guard Tory Jackson added 20 for fourth-seeded Notre Dame (24-7), which ended a six-game winning streak. Georgetown, which beat the Irish for the fourth straight time, also eliminated Notre Dame last year with a 67-63 win in the quarterfinals.

Jackson scored the first seven points during a 9-0 run that gave the Irish their last lead, 78-76, with 2:54 to go. The freshman had a three-point play, a layup after he spun around a defender in the paint, and the tying basket with 3:24 left.

"We were riding him there and he's a fearless young man," Notre Dame coach Mike Brey said. "Our guys understood to open the floor up and let him go. He made some great plays."
