The first round of the NCAA tournament is officially in the book, so it's time to look ahead to the matchups they have produced for the next round.
Here's a quick look at what you need to know for all eight of Saturday's second-round games.
East Region: No. 8 Wisconsin vs. No. 1 Villanova (approximately 2:40 p.m. ET)
Many said the Badgers were mis-seeded as an eight, and it looked that way in their opener, as Wisconsin took care of business in an 84-74 victory over Virginia Tech. Now the Badgers have an intriguing matchup with No. 1 overall seed Villanova. The Wildcats beat Mount St. Mary's 76-56, but were actually up by just one at halftime. Jay Wright's club better be careful in this one.
East Region: No. 5 Virginia vs. No. 4 Florida (approximately 8:40 p.m. ET)
Both the Cavaliers (vs. UNC-Wilmington) and Gators (vs. East Tennessee State) were trendy upset picks, but each survived and now face each other. For the Cavs, the key to beating Florida could be junior guard Marial Shayok. Virginia has been looking for a second scorer all year, and they got one in Shayok on Thursday, who put up a career-high 23 points. They'll need a similar effort against a potent Florida team.
Midwest: No. 5 Iowa State vs. No. 4 Purdue (approximately 9:40 p.m. ET)
With both the Cyclones and Boilermakers playing exceptionally well on Thursday it sets up what should be a must-see 4 vs. 5 matchup. Specifically it will be an exciting clash of styles, with Iowa State — led by point guard Monte Morris — taking on Purdue, who plays through Caleb Swanigan in the post. "Biggie" is the nation's second leading rebounder, including 14 in the Boilermakers' opening-round win over Vermont.
South Region: No. 12 Middle Tennessee vs. No. 4 Butler (7:10 p.m. ET)
The darlings of Thursday's afternoon session were the Middle Tennessee Blue Raiders, who — for the second year in a row — toppled a higher-seeded Big Ten team. The scary thing for their opponent Saturday (Butler) is how easy it came for the Blue Raiders, who got 19 points and nine rebounds from senior Reggie Upshaw. Butler cruised past Winthrop thanks to 18 points from Avery Woodson.
West Region: No. 8 Northwestern vs. No. 1 Gonzaga (5:15 p.m. ET)
The story of Thursday's afternoon session was Northwestern, which used a major gaffe from Vanderbilt to pick up the first NCAA tournament win in school history. Things won't be nearly as easy in Round 2 whey the Wildcats face top-seed Gonzaga. The Zags got double-digit scoring from four different players to cruise past South Dakota State in their opener.
West Region: No. 7 Saint Mary's vs. No. 2 Arizona (approximately 7:45 p.m. ET)
The Wildcats were arguably Thursday's most impressive team, cruising past North Dakota 100-82. However, Sean Miller's club will have his hands full with a Saint Mary's club that beat VCU by eight. The Gaels had five different players score in double-figures.
West Region: No. 11 Xavier vs. No. 3 Florida State (6:10 p.m. ET)
Florida State silenced Florida Gulf Coast in their opener and now has a tougher-than-it-looks-on-paper matchup with Xavier. The Musketeers were a preseason Top 10 team, and after a slew of injuries seem to be finally getting right. They largely dominated Maryland in Round 1, thanks to a 21-point performance from Trevon Bluiett.
West Region: No. 5 Notre Dame vs. No. 4 West Virginia (12:10 p.m. ET)
The Irish needed a last-second miss to survive against Princeton, but even as they advance, they will have their hands full with Bob Huggins' West Virginia club. The Mountaineers are one of the nation's most feared defensive teams, and actually forced more turnovers than anyone in the country at over 20 per game.
