NEW YORK -- It was only fitting that the last meeting between Georgetown and Syracuse, the foundation of the Big East Conference that has crumbled, went into overtime.
No. 19 Syracuse (26-8) prevailed in the tournament semifinal with a 58-55 over No. 5 Georgetown Friday night before a frenzied, sold out Madison Square Garden crowd.
Syracuse's Brandon Triche scored three points in the extra session, including a free throw that put the Orange up 58-55 with 18 seconds left.
The top-seeded Hoyas were looking to tie the game, but Otto Porter Jr.'s pass from the corner was picked off by C.J. Fair with 3.2 left. Fair was fouled, but missed both shots.
Jabril Trawick's heave for the Hoyas just beyond half court to tie it bounced off the backboard as time expired.
Triche's layup in traffic 10 seconds into the overtime gave Syracuse a 53-51 lead it never lost. Baye Keita's follow with 2:47 provided the Orange, seeded sixth in the tournament, a 55-51 advantage with 2:47 left.
Mikael Hopkins scored on a drive to draw the Hoyas to within two at 55-53 with 2:28 left, Fair's dunk moved the Syracuse cushion to 57-53 with 1:58 left.
Keita topped Syracuse with 13 points. Hopkins led the Hoyas with 15 points and eight rebounds.
Porter sent the game into overtime when he sank both ends of a one-and-one with 7.3 seconds left. Michael Carter-Williams 15 foot jumper went off the side rim for Syracuse as time expired.
Keita gave the Orange a 51-49 lead when he sank two free throws with 1:23 left to play.
The Hoyas trailed by as many as seven points in the second half, but methodically climbed back until finally tying the game at 49-49 on two free throws from Trawick at the 1:47 mark.
Georgetown's next possession came up empty due to a shot clock violation.
Syracuse, a charter Big East member, is headed to the ACC next season, while Georgetown will remain in a modified version of the conference.
The semifinal was the 14th Big East Tournament meeting between the two schools. The only other Big East series with more tournament games is Syracuse vs. Connecticut with 15.
Syracuse erased a 17-14 Georgetown lead by going on a 15-3 run to grab a 29-20 halftime lead. The run started with 8:05 left and featured little-used Trevor Cooney.
The sophomore swingman provided the spark off the bench, draining two 3-pointers and a layup in the burst. Cooney came in because Triche picked up two fouls with 13:58 still left in the half.
The Hoyas sank just 8 of their 26 shots from the field in the half.
