NCAA Tournament 2017: Saturday's 2nd-Round Scores, Updated Bracket and Schedule

The 2017 NCAA tournament rolled on Saturday with the start of the second round. The biggest question heading into the weekend was whether the event would finally start living up to its March Madness moniker after a pretty tame opening round in all four regions.

Saturday's action featured the potential for fireworks, with a pair of top seeds facing challenges from power-conference opponents in Villanova (vs. Wisconsin) and Gonzaga (vs. Northwestern). A few Cinderella stories were also on the slate with No. 11 seed Xavier and No. 12 seed Middle Tennessee.

Let's check out the complete schedule as well as the scores from the first day of Round 2, which will get updated through the conclusion of play. That's followed by a look at the current tournament bracket and a recap of each contest.

Updated Tournament Bracket

West Virginia 83, Notre Dame 71

The vaunted West Virginia press is heading to the Sweet 16 after keeping Notre Dame off balance most of the afternoon en route to a 12-point win at the KeyBank Center in Buffalo, New York.

The fourth-seeded Mountaineers held the fifth-seeded Fighting Irish to 40.7 percent shooting and forced 14 turnovers to help spearhead the victory. West Virginia, which led the nation in steals per game during the regular season, now has 13 through two tourney games.

Jevon Carter led the way offensively for WVU with 24 points on the strength of four three-pointers. The team as a whole shot 57.1 percent from long range. Daxter Miles Jr. added 18 points, while Esa Ahmad posted 11 points and nine rebounds.

Bonzie Colson shined in a losing effort for Notre Dame with 27 points and eight boards. His teammates combined to make just 12 of their 39 shots (30.7 percent), however, and Steve Vasturia (11 points) was the only other one to reach double figures in scoring.

Looking ahead, West Virginia advances to play the winner of the aforementioned clash between Gonzaga and Northwestern. If the Zags hold form, it will be intriguing to see whether they can generate open looks against the press after ranking second in field-goal percentage in the regular season.

Wisconsin 65, Villanova 62

A new champion will be crowned. Villanova's title defense came to an end as Wisconsin ended the game on a 15-5 run over the final five-and-a-half minutes to score the second-round upset.

The Wildcats, who trailed at halftime, fought back and looked ready to pull away after Donte DiVincenzo knocked down a three to put the reigning champs up seven with 5:31 to play.

The Badgers defense stepped up from there, though. It allowed the Big Ten side to slowly chip away at the lead. A couple of key buckets down the stretch, highlighted by a Nigel Hayes reserve layup with 14 seconds left, completed the comeback and punched Wisconsin's ticket to the Sweet 16.

Hayes was the team's leading scorer with 19 and also grabbed eight boards. Bronson Koenig enjoyed an efficient day from the field, knocking down seven of his 11 shots en route to 17 points. Ethan Happ added 12 points, eight rebounds and two blocks while battling through foul trouble.

Josh Hart paced Villanova with 19 points, but the offense became too reliant on him down the stretch and the Badgers were able to slow down his drives to the basket in crunch time. DiVincenzo tallied 15 points, six rebounds and three steals off the bench.

Wisconsin moves on to face Florida in the next round.

Gonzaga 79, Northwestern 73

Gonzaga held off a furious rally from Northwestern to avoid becoming the second No. 1 seed to get upset Saturday. The Bulldogs survived the storm to secure the six-point victory at the Vivint Smart Home Arena in Salt Lake City.

The West Region's top seed was up by 12 with less than nine minutes to play and looked primed to roll into the Sweet 16. The Wildcats rallied to within five but couldn't complete the miraculous comeback.

Nigel Williams-Goss paved the way for Gonzaga with 20 points, eight rebounds and four assists. Jordan Mathews chipped in 14 points and seven rebounds, while Zach Collins came through off the bench with 14 points and four blocks.

Bryant McIntosh matched Williams-Goss with a game-high 20 for Northwestern. Vic Law registered 18 points and eight rebounds. The team shot just 40.9 percent from the field and 33.3 percent from beyond the arc, though.

The win for the Zags sets up what should be a highly entertaining encounter with West Virginia. They will need to protect the ball much better against the press of the Mountaineers after turning it over 14 times to help keep the Wildcats in Saturday's game.

Xavier 91, Florida State 66

There will be at least one double-digit seed represented in the Sweet 16 after the Xavier Musketeers thrashed the Florida State Seminoles on Saturday night.

Head coach Chris Mack's burgeoning Big East squad was on fire all night, and it shot 55.6 percent from the field and 64.7 percent (11-of-17) from three in the 25-point rout.

Trevon Bluiett shined throughout, pouring in a game-high 29 points (8-of-14 shooting) as he burned FSU both inside and out. All told, Bluiett made three triples and 10 free throws to catapult Xavier into the regional semifinal.

Dwayne Bacon paced the Seminoles with 20 points, but a collective 4-of-21 shooting performance from beyond the arc doomed the boom-or-bust ACC contenders in the end.

By virtue of the win, the Musketeers will now meet the seventh-seeded Saint Mary's Gaels, who beat the second-seeded Arizona Wildcats in their Saturday night game.

Butler 74, Middle Tennessee 65

The Butler Bulldogs tamed the Winthrop Eagles with a sensational shooting display in the round of 64, and the same was true Saturday when they dispatched the Middle Tennessee Blue Raiders by nine points.

Butler shot 51.1 percent from the field as a team, including 53.3 percent from three, as Kelan Martin led the Bulldogs with 19 points to clinch a Sweet 16 berth for the first time in six years, per USA Today's Nancy Armour:

However, it wasn't just about offense.

The Bulldogs also clamped down on the Blue Raiders' vaunted attack and limited the South Region's No. 12 seed to 4-of-19 shooting from three.

Furthermore, MTSU stud scorer Giddy Potts was held scoreless on 0-of-8 shooting (0-of-3 from three) in 35 minutes.

Now headed to the NCAA tournament's second weekend, Butler will square off against the North Carolina Tar Heels or Arkansas Razorbacks with a spot in the Elite Eight on the line.

Arizona 69, Saint Mary's 60

It wasn't pretty, but the Arizona Wildcats are moving on to the Sweet 16 after surviving a scare from the Saint Mary's Gaels.

The Wildcats trailed by one at the break as they struggled to score against the Gaels' stout defense in the first half, but a 40-point surge in the second half allowed head coach Sean Miller's club to take home the win.

Lauri Markkanen starred for Arizona with 16 points, 11 boards and two blocks, and he was joined in double figures by Allonzo Trier (14 points), Kadeem Allen (12 points) and Dusan Ristic (13 points).

Saint Mary's, meanwhile, was paced by 19 points, 11 boards and four dimes from stud big man Jock Landale.

With the round of 32 triumph in tow, Arizona will now turn its attention the Musketeers in what could be a regional semifinal matchup devoid of defense.

Florida 65, Virginia 39

The Florida Gators cruised into the Sweet 16 with a 26-point win over a Virginia Cavaliers team that was listless to a historic degree, per ESPN Stats & Info:

While it's no secret the Cavaliers had trouble scoring all year long, their performance Saturday evening was eye-opening, to say the least. In the 26-point loss, head coach Tony Bennett's squad shot just 29.6 percent from the field and 1-of-15 (6.7 percent) from three.

Conversely, the Gators drilled 46 percent of their total shots and converted eight triples, as Justin Leon and Devin Robinson dropped 14 points apiece to lead Florida's balanced attack.

Now in something of a groove, the Gators will attempt to replicate Saturday's stellar effort when they square off against the Badgers at Madison Square Garden.

Purdue 80, Iowa State 76

The Purdue Boilermakers and Iowa State Cyclones saved the best for last Saturday night, as the Big Ten ballers snagged a tight four-point win on the back of Caleb Swanigan.

Not only did Swanigan pour in 20 points and dole out seven assists, but he came up with 12 rebounds—including a clutch board with 10.5 seconds remaining that set up game-clinching free throws, as NCAA March Madness documented on Twitter:

Vincent Edwards got in on the action with 21 points and 10 boards of his own, while Isaac Haas rounded out Purdue's trio of double-figure scorers with 14 points on 6-of-8 shooting.

Not to be forgotten, Iowa State's Deonte Burton went nuclear in the second half and nearly willed the Cyclones to victory as he finished with 25 points. Cyclones point guard Monte Morris added 18 points and nine dimes in the loss.

Next up for the Boilermakers is the winner of Sunday's round-of-32 clash between the top-seeded Kansas Jayhawks and ninth-seeded Michigan State Spartans.
