NEW ORLEANS — Matt Howard and Butler are starting to make this look a little bit easier.

NEW ORLEANS — Matt Howard and Butler are starting to make this look a little bit easier.

After narrowly surviving its first two NCAA tournament games by margins of two points or less, Butler led by 20 points before holding on for a 61-54 victory over Wisconsin on Thursday night.

Now the Bulldogs are a win away from their second straight Final Four appearance.

Howard had 20 points and 12 rebounds, Shelvin Mack scored 13 points and Shawn Vanzant 10 for the eighth-seeded Bulldogs (26-9), who upset top-seeded Pittsburgh by one point in the second round and now have knocked off another higher seed in fourth-seeded Wisconsin.

The victory sent Butler into the Southeast regional final, where the Bulldogs meet second-seeded Florida (29-7) on Saturday for a trip to the Final Four.

Jordan Taylor scored 22 for Wisconsin (25-9), which shot 30.4 percent (17 of 56). Jon Leuer, normally one of the Badgers' top offensive forces with 18.7 points per game coming in, was 1 of 12 shooting and finished with three points.

Butler was the aggressor from the outset, using quickness and heady play to counter Wisconsin's size advantage. The Bulldogs took a 6-5 lead on Vanzant's 3 from the corner and never trailed again in the first half.

While the Bulldogs shot 50 percent (12 of 24) in the opening 20 minutes, their defense was equally impressive. Wisconsin came in averaging only 7.5 turnovers per game, but had eight in the first half alone. Taylor, who entered the contest with the nation's best assist-to-turnover ratio at 4.18, had one assist and two turnovers to that point.

The Badgers' shooting woes only made matters worse. They missed 15 of their first 23 shots. They also uncharacteristically missed four of their first eight free throws after coming in with nation's best .823 free throw percentage.

Wisconsin wound up with 11 turnovers for the game and went 13 of 19 (68.4 percent) from the foul line.

Butler began to gradually pull away when Smith scored inside and Chase Stigall turned a steal into a transition 3 to make it 23-16.

The Bulldogs later scored the final four points of the first half on Smith's free throw and Howard's second 3 in as many tries, giving Butler a 33-24 lead heading into the locker room.

Butler then scored the first nine points of the second half, with Mack scoring five during the spurt, to open up a 42-24 lead.

Florida 83, BYU 74

At New Orleans, Alex Tyus scored 19 points and grabbed 17 rebounds to help Florida chase Jimmer Fredette and the Cougars (32-5) out of the NCAA tournament.

While Fredette was the star attraction, scoring 32 points on 11 for 29 shooting in the final game of his college career, Florida countered with balance.

Kenny Boynton added 17 points while Erving Walker and Chandler Parsons both scored 16. Boynton and Parsons each hit 3-pointers in overtime as Florida (29-7) outscored BYU 15-6.

Fredette made just 3 of 15 from 3-point range and had to work for his points against Florida's physical defense. By the end of the game, he had a bandage on his chin from a blow in the second half, but the baskets kept coming until he was held scoreless in overtime.

Connecticut 74,San Diego State 67

At Anaheim, Calif., Kemba Walker scored 22 of his 36 points in another dynamic second-half performance, and Connecticut moved to the brink of its fourth trip to the Final Four.

Freshman Jeremy Lamb added 24 points and hit a clutch 3-pointer with 1:43 left for the third-seeded Huskies (29-9), who needed five wins in five days to capture the Big East tournament before advancing to an NCAA regional final for the 10th time.

D.J. Gay scored 16 points for the second-seeded Aztecs (34-3), who couldn't quite catch up to Walker during a scintillating second-half stretch run.

Walker scored 12 consecutive points for UConn in that late duel with Gay, whose 3-pointer cut the Huskies' lead to 65-64 with 2:53 left. Lamb replied with his 3 before an emphatic last-minute dunk.
