Green spun and banked in a short, off-balance shot with 2.5 seconds to play and the Hoyas earned a harder-than expected 66-65 victory over Vanderbilt in the East Regional semifinals tonight.

The victory was the seventh straight and 18th in 19 games for second-seeded Georgetown (29-6) and put them in the regional final for the first time in 11 years.

Vanderbilt (22-12) had one last chance to win the game but a long 3-pointer by Alex Gordon was contested by Green, the Big East player of the year.

The sixth-seeded Commodores had taken a 65-64 lead with 17.9 seconds to play when Dan Cage hit two free throws after being fouled grabbing the rebound of a Patrick Ewing Jr.'s missed jumper.

After a timeout, Georgetown inbounded the pass and Jessie Sapp brought the ball upcourt and gave it to Green at the foul line extended.

Green started to make a move and fumbled the ball. He recovered, made a turnaround move and banked home the short jumper. Replays seemed to indicate he may have walked by switching his pivot foot.

Green came up big with the Hoya's big man on the bench. Roy Hibbert, the 7-foot-2 center, had fouled out with 3:58 to play and Georgetown down 58-57.

Green finished with 15 points for Georgetown, which rallied from an eight-point halftime deficit against the Commodores. Hibbert added 12 points and 10 rebounds — mostly all in the second half. Freshman DaJuan Summers added 15 points, including three clutch 3-pointers in the second half.

Cage and SEC player of the year Derrick Byars had 17 points apiece to lead Vanderbilt, which was looking to reach the regional final for the second time in school history. Shan Foster added 16 points.
