Just four teams remain in the 2013 NCAA Tournament.

Louisville, Michigan, Syracuse and Wichita State all have a chance to win this year’s national championship. They will compete in the Final Four on Saturday in Atlanta.

Since the field of 68 was formed, Louisville has been the favorite to win it all. The Cardinals’ Big East Championship victory propelled them to the No.1 overall seed in the tournament, and they are still expected to cut down the nets next Monday.

The online betting Web site Bovada has updated Louisville’s odds of winning the Final Four at -150. The Cardinals are heavy favorites after having gone through the Midwest Region with ease. They won their four tournament games by an average of 21.75 points. Louisville even beat No.2 Duke by 22, despite losing Kevin Ware to a gruesome leg injury.

The worst odds of winning the title belong to Wichita State. The Shockers head to Atlanta with their odds set at +1200.

The No.9 Shockers may be the most surprising team of March Madness, even with FGCU’s run to the Sweet 16. Only four other teams seeded ninth or lower have reached the Final Four. None of them made it to the championship game.

Michigan’s odds of +300 make them the second favorite to be crowned the best team in college basketball. They were atop the national polls for a short time in the regular season, but fell to a four-seed in the South because of a tough stretch of games in February.

The Wolverines came dangerously close to not even reaching the Elite Eight. They trailed No.1 Kansas buy 11 points with less than four minutes remaining in their Sweet 16 matchup. A three-pointer by Trey Burke sent the game into overtime, where Michigan pulled out the 87-85 victory.

Syracuse will take on Michigan in the late game of Saturday’s Final Four action. Bovada has set the Orange’s odds to win the 2013 NCAA Tournament at +425.

The No.4 Orange made it out of the East Region by playing suffocating defense. They’ve allowed less than 46 points per game in the tournament and shut down No.1 Indiana with their 2-3 zone.

Both of Saturday’s matchups are firsts for the 2012-2013 college basketball season. Louisville and Syracuse, though, have already played each other three times in 2013.
