Otto Porter had 17 points and grabbed the game's decisive rebound with 1.4 seconds to play Saturday, leading Georgetown to a 53-51 win over No. 5 Louisville, the Cardinals' third straight loss.

Trailing by one, Louisville had several chances to take the lead in the final 2 minutes. After getting the ball back on a disputed held ball ruling, the Cardinals kept the ball for a final shot. Peyton Siva, who didn't score in the game, missed the jumper, Porter grabbed the rebound and was fouled.

Porter finished with 12 rebounds for the up-and-down Hoyas (14-4, 4-3 Big East), who prevailed in another fast-paced entertaining game to go with the poor-shooting clunkers they have had this season. Georgetown has beaten ranked teams Notre Dame and Louisville in consecutive games, quite a contrast from laborious losses to South Florida, St. John's and Pittsburgh.
