Half of this year's Final Four is set, and today we'll find out which other two teams will be joining Big East powers Connecticut and Villanova in Detroit next week. Find out who's still alive and who's going home with more analysis from Sunday's Elite Eight games.

Midwest Regional: Michigan State 64, Louisville 52

Louisville came into its Elite Eight matchup having posted wins over Morehead State, Siena and Arizona as the NCAA tournament's No. 1 overall seed, but this one was all Michigan State from the start. The Spartans lit up Rick Pitino's pressing defense with a 50-percent clip from beyond the arc and dominated the paint with a commanding 35-27 rebounding advantage to reach the Final Four for the first time in four years. Much of that discrepancy on the glass was due to Tom Izzo's frontline of center Goran Suton and reserve forward Draymond Green, who each tallied 10 rebounds and shut down Louisville big man Samardo Samuels. The 6-foot-9 freshman forward from Jamaica, in fact, was held to no points for only the second time this season (the other time coming at Connecticut on Feb. 2) while committing four turnovers and three fouls in 22 minutes. Suton, meanwhile, was just as influential on the offensive end as he was defending Samuels, scoring 17 points in the first half and finishing with a team-high 19 with a 3-for-5 shooting performance from three in addition to four assists. The Spartans also got a lift off the bench from sophomore guard Durrell Summers, who played 25 minutes and chipped in 12 points on 4-of-6 shooting from the floor, and Sweet 16 hero Kalin Lucas added 10 points, five assists and three rebounds in the 64-52 victory at Lucas Oil Stadium. Louisville's backcourt, on the other hand, struggled considerably against Michigan State's defense, as Andre McGee was held scoreless and Jerry Smith finished with just eight points. Junior wing Earl Clark led the way for the Cardinals with 19 points, but senior forward Terrence Williams couldn't have finished out his career at Louisville in a worse way, making only one of his seven field-goal attempts to finish with five points, six rebounds and four assists. While it was a sad ending for Williams, Izzo couldn't be happier for his team, which gets the opportunity to play only 90 minutes away from its East Lansing campus next Saturday against Connecticut. "Detroit, here we come," the 14-year coach said after the win Sunday. "I can't tell you how much I'm looking forward to that."

South Regional: North Carolina 72, Oklahoma 60

While those of you at home finally got to see one of the most anticipated matchups between two of the country's best big men, this one was never really close. Blake Griffin certainly got the better of Tyler Hansbrough with a game-high 23 points and 16 rebounds, but it's the Tar Heels who are headed back to the Final Four for a second straight year and a record 18th time (UCLA also has 18 but its appearance in 1980 Final Four was later vacated by the NCAA because of rules violations) after claiming a 72-60 win in Memphis. Hansbrough, surprisingly enough, never found his rhythm against the Sooners, getting into early foul trouble and finishing with only eight points, six rebounds and three assists - just the third time this season the North Carolina senior didn't score in double figures. But Roy Williams' team found its offensive chemistry through senior wingman Danny Green, who scored 14 of his 18 points in the first half to help UNC grab a nine-point lead at halftime. From there, it was junior point guard Ty Lawson who took over, canning 6-of-13 from the field - including 2-of-4 from three and 5-of-6 from the free-throw line - to lead the Tar Heels with 19 points, five assists and five rebounds. Oklahoma's floor leader Austin Johnson, however, didn't have the same kind of success Sunday, struggling to find his shot and managing to muster up only two points and three assists in 29 minutes. The Sooners did get a solid effort in the backcourt from freshman guard Willie Warren (18 points and three assists), but Jeff Capel's club couldn't stay with the ACC regular-season champs, largely because of its 2-for-19 effort from three - Oklahoma missed its first 15 attempts from behind the arc - and its perimeter defense against North Carolina's backcourt.
