Connecticut played every late possession to near perfection, bleeding the clock and usually getting points.
The biggest one came from Boatright, who splashed a 10-foot floater as the shot buzzer sounded, making it 56-50 with 4:09 remaining. Only minutes earlier, Boatright had gone to the bench with a slight ankle sprain, but he was determined to fight through.
"I've got a lot of heart and I wasn't coming out," Boatright said. "We put in too much work all year for me to give up on an ankle sprain."
The Wildcats answered with an Alex Poythress follow slam, but he missed a free throw that would have cut it to three, and after DeAndre Daniels scored inside for the Huskies, Kentucky never got the ball back with a chance to tie or take the lead.
The final two minutes passed and Kentucky coach John Calipari decided not to put Connecticut at the line. This allowed the Huskies to burn the clock and keep the ball in the hands of senior point guard Shabazz Napier.
He did wonders with it.
Napier, voted the Final Four's most outstanding player, was a maestro throughout the tournament, and especially on Monday. His 22 points led the way. Napier set the early tone with three-point shooting and controlled the action late.
Napier will now go down with Kemba Walker, Emeka Okafor, Rip Hamilton, Ray Allen and all those other UConn greats. This adds to the school's titles in 1999, 2004 and 2011.
"When they say Ray, Rip, Ben, Emeka, Kemba -#8212; they'll soon say Shabazz," said their former coach, Jim Calhoun, who was in the crowd along with former Presidents Bill Clinton, George W. Bush.
When Kentucky's James Young started an 8-0 run with an acrobatic slam for three-point play, it appeared the Wildcats were in a position to take its first lead.
But Napier banged in a three-pointer.
"Dagger," Calipari said.
Teammate Niels Giffey followed with a corner three, and at the moment it looked like Connecticut could pull it off. This from a team that lost to Louisville by 33 points late in the season.
But in the second year under Ollie, the former UConn player and hand-picked successor for three-time national champion Jim Calhoun, the Huskies were never deterred.
They were underdogs in the national title game to a team that seemed even more destined.
Youth made Kentucky the story entering the game. When the starting five took the floor, it marked the second time in NCAA Tournament history that an all-freshman squad opened a championship game. It first happened in 1992 when Michigan faced Duke.
This was an eighth-seeded team that had lost 10 games during the season.
But the inexperience hadn't been a factor in the tournament as the Wildcats took down Kansas State, Wichita State, Louisville, Michigan and Wisconsin, reaching the final for the second time in three years.
And in the previous four games, the Wildcats won them in clutch fashion. Guard Aaron Harrison was the hero in the previous three with a stretch of late-moment game-winning shots unparalleled in the tournament's history.
