Indianapolis – Nobody will accuse these Kentucky kids of being the fastest learners. Not this season. And certainly not during most of Friday night's game against Louisville.

But once again, late in the game with everything on the line, they figured things out just in time.

Aaron Harrison hit a three-pointer for the go-ahead score with 39 seconds left Friday night and Julius Randle made a pair of clutch free throws to lift the fantastic freshmen of Kentucky to a 74-69 victory over their in-state rivals.

The eighth-seeded Wildcats (27-10) led for a grand total of 65 seconds in this Midwest Regional semifinal. They'll play Michigan on Sunday for a trip to the Final Four.

"I told them before the game, you'll get punched in the mouth and you're going to taste blood," coach John Calipari said. "You can fight or you can brace yourself for the next shot. They fought."

Fourth-seeded and defending champion Louisville ended its season at 31-7.

Few expected a run this deep for the Wildcats as this season played out, and their five freshmen starters struggled to play a team game. But they've been learning slowly. They trailed by 13 midway through the first half, then by seven with 4 minutes left.

A 7-0 run tied the game at 66 with 2:11 left and the Kentucky freshmen showed their poise against a team led by senior Russ Smith with 23 points.
