Two tickets to next weekend's Final Four were punched on Saturday, with both games living up to the thrilling form of Thursday night's contests. In the Southeast final Butler made a bit of history, becoming the first team to make consecutive trips to the Final Four when being seeded three or lower with a 74-71 overtime win over Florida. Shelvin Mack scored a game-high 27 points, Matt Howard added 14 and freshman Khyle Marshall scored 10 off the bench. Also, Butler's three-point defense was a factor in the win as they limited the Gators to 3-for-14 on the afternoon.

The first two tickets to the Final Four will be punched on Saturday, and one can make a good argument that three of the four teams slated to play were not supposed to have reached this point. But what's expected beforehand means nothing when compared to actual achievement, which is why Butler, Arizona and Connecticut all find themselves 40 minutes away from a trip to Houston. Two of the best players in the nation will be on display in the West final in Arizona's Derrick Williams and Connecticut's Kemba Walker.

Countless times over the past few weeks Kentucky head coach John Calipari has noted that his upperclassmen deserve some of the credit for the Wildcats' improved play as many rush to credit the highly-touted freshman class. Friday night was just the latest example of what the veterans mean to the team but when the game is on the line the basketball will end up in the hands of a freshman. Just as he did in the second round against Princeton Brandon Knight struggled offensively, shooting 2-for-9 over the first 39 minutes of the game.

The East Regional tips off tonight at the Prudential Center in Newark, N.J. and while three of the top four seeds have done as expected in reaching this point, there is a surprise as well. Marquette, who looked like a mediocre basketball team in their regular season finale against Seton Hall in this same arena, has knocked off Xavier and Syracuse to reach this point. North Carolina and Kentucky had turning points as well, with the Tar Heels improving once Kendall Marshall took over at the point and the Wildcat veterans stepping up late in the season has helped them.

Of the four games played on Thursday night the matchup between West top-seed Duke and five-seed Arizona was the game people thought could provide a double-digit margin. The defending national champions were a solid favorite going in and they played as such in the first half, taking a 44-38 lead into the locker room thanks to a 16-6 edge in points in the paint and 12-5 in points off turnovers. Kyle Singler and Kyrie Irving scored 14 points apiece to lead the Blue Devils, who were far more balanced than an Arizona team that featured a lot of Derrick Williams and little of much else.

The NCAA Tournament moves on to the regional rounds this weekend, beginning with matchups in the West and Southeast regions on Thursday night. The West has gone mostly according to form with the top three seeds arriving in Anaheim, joined by five-seed and Pac-10 regular season champ Arizona. Each of the four teams has an All-America candidate on its roster but the five national titles the head coaches account for below to two: Duke's Mike Krzyzewski (three) and Connecticut's Jim Calhoun (two). Below is a preview of each of the two games, both of which can be seen on CBS Thursday night.
