HOUSTON — We’re not done yet! Unfinished business, baby!” That was the rallying cry from the Butler Bulldogs, who are headed back to the title game, not as lovable underdogs but a team intent on making up for last year’s heartbreak.Maybe this time that final, riveting shot will go in.Maybe this time Butler won’t need it.Shelvin Mack scored 24 points, Hahn scored all eight of his points during a 90-second span in the second half that gave Butler control of the game for good and the Bulldogs shut down hot-shooting Virginia Commonwealth with their trademark unforgiving defense. The eighth-seeded Bulldogs (28-9) will face Connecticut on Monday night, the lowest-seeded team to play for the national title since Villanova won it as a No. 8 seed in 1985. VCU (28-12) sure didn’t look like a team critics dismissed as “unworthy” — and a whole lot worse — after it skidded into the NCAA tournament with five losses in its last eight games. But Butler’s stifling defense was too much for the Rams, only the third No. 11 seed to reach the Final Four.But not enough of them.Jamie Skeen scored 27 and Bradford Burgess had 15, including three 3-pointers before the game was even seven minutes old. But Stevens is known for his tactical acumen, and this game was no different. He tweaked Butler’s defense, and Burgess had just one more three the rest of the night.

When the options boil down to winning or heading home, nobody’s better than Kemba and Connecticut.Kemba Walker scored 18 points Saturday night to lift UConn to its 10th straight victory since finishing off a .500 Big East regular season, a 56-55 win over cold-shooting Kentucky that moved the Huskies a victory away from their third, and most improbable, NCAA title.Walker, a quick-handed junior from the Bronx, added seven assists and six rebounds to help the young UConn team (31-9) extend a winning streak that started with a five-wins-in-five-nights leg-drainer at the conference tournament and now includes five more at the tournament that really counts.The third-seeded Huskies — lowest seed left in a tournament that has been as unpredictable as any in history — will face No. 8 Butler, a 70-62 winner over 11th-seeded VCU in the first semifinal, on Monday. But this win, which improved Calhoun to 5-1 in his four Final Four appearances, was not a work of art on either end.Fourth-seeded Kentucky (29-9) shot 33.9 percent for the game and went 5:39 without a point late in the second half. UConn wasn’t much better, but Walker, Alex Oriakhi and Shabazz Napier all made baskets to turn a 48-48 tie into a 54-48 lead with 2:29 left. DeAndre Liggins made a 3-pointer for the Wildcats to cut the deficit to three, and Kentucky had its chances. But Brandon Knight, one of John Calipari’s three sensational freshmen, barely drew iron on a 3-pointer. After Kentucky got the rebound, Liggins drew a foul but only hit one of two free throws.Kentucky forced one more turnover and went for the win, but this time, it was Liggins whose 3-pointer was short. Napier made two free throws to make it 56-52, then Knight ended the game with a 3-pointer at the buzzer — a meaningless make and a cruel close to what has otherwise been a remarkable season for Calipari and Co. — Kentucky’s first trip to the Final Four since winning it all in 1998. The Wildcats, the nation’s all-time winningest program, stayed stuck on 105 NCAA-tournament wins in the program history, still tied for first with North Carolina, the team they beat to get here.
