An acrobatic tip-in from a player who has scored all of 49 points in three seasons at Georgetown has put No. 5 Louisville into must-win mode. Aaron Bowen contorted his body enough to guide in the ball after a missed layup by D'Vauntes Smith-Rivera with 3 1/2 minutes to play Saturday, the unlikely winning basket in the Hoyas' 53-51 victory which was the Cardinals' third straight loss.
