Final Four: Duke Coach K makes his 13th trip where they are joined by another regular Villanova making their 7th appendence.

SAN FRANCISCO (AP) — Mike Krzyzewski slowly climbed up the ladder, bowed to the adoring Duke fans and then pointed to his players to give them the credit before cutting the final string of the net.

Coach K’s farewell tour will end at his record-setting 13th Final Four.

The Blue Devils delivered their most complete performance of this NCAA Tournament run to extend the career of their Hall of Fame coach for one more weekend after beating Arkansas 78-69 on Saturday night in the West Region final.

“To see the joy, I can’t explain it, because, you know, I’m a grandfather, I’ve lived through my daughters, I’m living through my grandchildren but now I’m living through these guys,” Krzyzewski said on the court before cutting down the net. “Holy mackerel!”

A.J. Griffin scored 18 points, West Region MVP Paolo Banchero added 16 and and second-seeded Duke (32-6) frustrated fourth-seeded Arkansas (28-9) on the offensive end to get back to the Final Four for the first time since Krzyzewski won his fifth championship in 2015.

Coach K will try to follow the path of the only coach to win more NCAA men’s titles as John Wooden won his 10th championship in his final season at UCLA in 1975. Krzyzewski broke the tie he had with Wooden for most Final Four appearances with the commanding win over the Razorbacks.

SAN ANTONIO (AP) — Villanova coach Jay Wright has won national championships with well-balanced and fundamentally sound teams, yet even he knew staying in contention for another title was going to take a rugged and exhaustive effort.

Ugly at times, the final result was beautiful for the Wildcats, who are going to their third Final Four in the past six NCAA Tournaments.

Jermaine Samuels had 16 points and 10 rebounds as Villanova grinded out a 50-44 victory over gritty and athletic Houston team in the South Region final Saturday.

“You just knew watching this team defensively, like you weren’t going to come out and just outscore them,” Wright said. “We really weren’t talking as much at the end about how we were going to score. We were talking about how we were going to stop them.”

Caleb Daniels added 14 points for the Wildcats (30-7), and fifth-year senior Collin Gillespie’s only made field goal was a clutch shot late, even though Villanova led throughout to clinch the first spot in this year’s Final Four in New Orleans.
