Storrs, CT (Sports Network) - Otto Porter Jr. carried the Hoyas again.

Porter scored all but one of his 22 points after halftime, including the game- winning basket with 9.5 seconds left in double-overtime to give No. 7 Georgetown a miraculous 79-78 road victory over Connecticut.

Georgetown blew a 12-point lead in the final four-plus minutes of regulation when Omar Calhoun made a game-tying 3-pointer with 2.2 seconds on the clock.

The Hoyas then found themselves down by seven in the last two minutes of the second OT before a pair of 3-pointers -- and Porter's dribble-drive through three defenders -- gave them a 79-78 lead with 9.5 ticks left.

Huskies guard Ryan Boatright, who missed a buzzer-beater at the end of the first extra session, was forced into the corner and came up empty on a desperation try as time expired.

The thrilling win marked the 10th straight for Georgetown (22-4, 12-3 Big East), which stayed atop the Big East standings with another tough road win after ending Syracuse's lengthy home winning streak last Saturday.

UConn (19-8, 9-6) lost for the first time in six games at Gampel Pavilion this season.
