Rick Pitino got the best of his protege Billy Donovan once again.
Chane Behanan netted 17 points, including the go-ahead jumper with 1:04 remaining, as Louisville punched its ticket to the Final Four with a 72-68 triumph over Florida in the West Regional Final.
After Russ Smith nailed a pair of foul shots to put Louisville up by three with 16 seconds left, Bradley Beal and Erving Walker each missed their three- point attempts in the final 11 seconds.
Smith added 19 points for the fourth-seeded Cardinals (30-9), who stormed back from an 11-point second-half deficit and closed the game on a 23-8 run. Peyton Siva had nine points and eight assists, but fouled out with 3:58 to play.
Louisville will play the winner between Kentucky and Baylor in next week's Final Four in New Orleans.
The seventh-seeded Gators (26-11), who were 8-of-11 from beyond the arc in the opening 20 minutes, became stagnant offensively in the second stanza.
Florida went 0-for-9 from three in the second half.
Bradley Beal and Erik Murphy tallied 14 points apiece to pace the Gators.
