CHARLOTTE - Tyler Hansbrough always found a way for North Carolina, whether it was carrying the Tar Heels when they lost their point guard or making a shot despite every defender knowing the ball would end up in his hands.

Now, with his relentless drive and unyielding will, Hansbrough has the Tar Heels back in the Final Four.

Hansbrough had 28 points and 13 rebounds Saturday night to help the Tar Heels hold off Louisville 83-73 in the East Regional final. Playing in front of a partisan home-state crowd, they reached the national semifinals for the first time since winning the championship in 2005.

The Tar Heels (36-2) advanced to play the Kansas-Davidson winner next Saturday at San Antonio, setting up a potential matchup between Hall of Fame coach Roy Williams and the Jayhawks program he left behind when he returned to his alma mater in 2003.

On this night, however, the focus was squarely on the Atlantic Coast Conference’s player of the year.

Battling in a physical contest inside, Hansbrough finished 12-for-17 from the floor in 38 minutes and was named regional MVP. That included a pair of clutch jumpers over the outstretched arms of 6-11 center David Padgett as the Tar Heels desperately tried to hold their tenuous second-half lead in the final minutes.

“He does the same thing in practice every day,” Williams said. “He is the most driven, focused player I’ve ever seen in my life. He wants to be the best player he can be and win.

“That’s Tyler Hansbrough. That’s Tyler Hansbrough at practice every day. That’s Tyler Hansbrough on off days. That’s who Tyler Hansbrough is.”

For Hansbrough and his teammates, it was a reversal from last year’s second-half collapse against Georgetown in the NCAA tournament’s round of eight. This time, the tournament’s No. 1 overall seed got to cut down the nets instead of heading to the locker room to wait for next year.

The Tar Heels have won all four of their games in this tournament by double digits. All four victories came in their home state, too, allowing them to celebrate in front of plenty of blue-clad fans Saturday.

“My feelings right now are great,” Hansbrough said. “This just kind of takes all those bad experiences away. At the same time, we want to accomplish more.”

Ty Lawson added 11 points — including a key 3-pointer with about 5 minutes left — for North Carolina, which blew a 12-point halftime lead, then broke away from a tie at 59 to earn their 17th trip to the Final Four.

Last year, nobody could hit a shot when the Tar Heels needed one most against the Hoyas in a loss that had stayed with them all season. But this time, the Tar Heels played with steady poise when the third-seeded Cardinals (27-9) erased the margin and traded baskets with them in the anxious final minutes.

First, with the Tar Heels clinging to a 68-64 lead, Lawson came around the baseline and knocked down a 3 from the corner in front of his bench that pushed the margin to seven. Then, after a basket from Earl Clark inside, Hansbrough knocked down a straightaway jumper over the 6-foot-11 Padgett to make it 73-66 with 2:27 to play.
