Saturday Recap

West Virginia 83, Notre Dame 71

The West Virginia Mountaineers are in the Sweet 16 for the second time in three years following an 83-71 win over the Notre Dame Fighting Irish.

Defense has been West Virginia's calling card for much of the season, as the team ranks fifth in adjusted defense on KenPom.com. Efficient shooting, however, was the key to the Mountaineers' victory.

They were 8-of-14 from three-point range as a team and made 50 percent of their 54 field-goal attempts. ESPN's Jay Bilas noted such hot shooting was a departure from the regular season:

Jevon Carter was 4-of-5 from beyond the arc en route to a 24-point game.

Bonzie Colson tallied a game-high 27 points, but West Virginia did a good job hounding Notre Dame's second-leading scorer, V.J. Beachem. The senior forward scored nine points on 2-of-14 shooting and was 1-of-9 from the perimeter.

Wisconsin 65, Villanova 62

College basketball will have a new national champion after the Wisconsin Badgers upset the Villanova Wildcats 65-62.

After Vitto Brown missed a foul shot, Donte DiVincenzo grabbed the rebound, giving Villanova the faint chance of tying the game. However, he struggled to deal with a double team by the Badgers, and his pass to Jalen Brunson came too late to get a shot off. NCAA March Madness shared a replay of the finish:

The senior duo of Nigel Hayes and Bronson Koenig stepped up for Wisconsin. Hayes scored 19 points and collected eight rebounds, while Koenig scored 17 points.

Kris Jenkins, on the other hand, had a day to forget. Last year's hero in the national championship shot 2-of-9 and scored six points.

Gonzaga 79, Northwestern 73

The Northwestern Wildcats' maiden voyage into the NCAA tournament lasted two games after they fell 79-73 to the Gonzaga Bulldogs.

Gonzaga's win wasn't without controversy. With four minutes, 57 seconds left in the game, Zach Collins was credited with a block on Derek Pardon as the Zags hanged onto a 63-58 lead. However, replays showed Collins reached his right hand up through the basket, which should've been basket interference.

Instead, Northwestern head coach Chris Collins was assessed a technical foul after arguing the call. Nigel Williams-Goss made two free throws to make it a seven-point game.

While the blown call impacted the game, it would be a stretch to say it altered the outcome. Gonzaga led by 18 at halftime and was in the driver's set for much of the evening.

Xavier 91, Florida State 66

One could be forgiven for forgetting the 11th-seeded Xavier Musketeers were supposed to be the underdogs against the third-seeded Florida State Seminoles.

Xavier shot 55.6 percent from the field and 64.7 percent from three-point range as they beat FSU by 25 points, 91-66.

ESPN.com's Jeff Borzello praised Xavier head coach Chris Mack for putting his team in a great position to succeed Saturday:

CBSSports.com's Matt Norlander thought the Musketeers played up to their March reputation and the Seminoles played down to theirs:

Trevon Bluiett had a nice game, leading Xavier with 29 points, six rebounds and three assists. 

Butler 74, Middle Tennessee 65

The Butler Bulldogs survived a tough game against the Middle Tennessee Blue Raiders to advance to the Sweet 16 for the first time since the second of their back-to-back runner-up finishes in 2011.

It's an impressive result for a team the Big East coaches picked to finish sixth in the conference at the start of the 2016-17 season. While the Bulldogs haven't enjoyed the same success they had under Brad Stevens, CBS Sports' Gary Parrish showed how Butler head coach Chris Holtmann is building a strong resume:

Kelan Martin came off the bench to lead Butler with 19 points, adding six rebounds and four assists to a solid all-around performance.

JaCorey Williams scored a game-high 20 points, but the Bulldogs did a great job of keeping Middle Tennessee's second-leading scorer, Giddy Potts, in check. Potts missed all eight of his field-goal attempts and failed to score a single point. 

Arizona 69, Saint Mary's 60

The Arizona Wildcats used a big second half to earn a 69-60 victory over the Saint Mary's Gaels and a trip to the Sweet 16 for the fourth time in five seasons. 

After trailing 30-29 at halftime, Arizona shot 56 percent from the field in the second half. Four of the Wildcats' five starters scored in double figures, with Lauri Markkanen leading the way with a double-double of 16 points and 11 rebounds. 

Greg Hansen of the Arizona Daily Star pointed out a key stat that helped carry the Wildcats to victory:

Arizona's size and ability to attack the basket overwhelmed Saint Mary's. The Wildcats attempted 15 more free throws than the Gaels, which was also stifled from three-point range (5-of-21). 

Jock Landale did have a strong game in defeat. The Saint Mary's junior scored a game-high 19 points and grabbed 11 rebounds. He and Calvin Hermanson combined to make 14 of the team's 25 field goals. 

Florida 65, Virginia 39

The Florida Gators continue to roll in the NCAA tournament, earning a spot in the Sweet 16 with a 65-39 blowout win over the Virginia Cavaliers.

Things fell apart for Virginia after a solid start, per ESPN's Jeff Borzello:

At the time of the sixth made field goal, Virginia actually held a 13-11 lead. Florida would close the first half on a 20-6 run to take control of things and it would only get worse in the second half. 

Virginia's 39 points also put it on a very dubious list in NCAA tournament history, per ESPN Stats & Info:

None of the Cavaliers players reached double figures in scoring, including three starters who were held scoreless. 

Things have worked out great for Florida to make a deep tournament run. The Gators were able to avoid No. 1 seed Villanova in the Sweet 16 after Wisconsin knocked out the defending national champions. 

Purdue 80, Iowa State 76

Holding off a furious second-half rally, the Purdue Boilermakers reached the Sweet 16 with an 80-76 victory over the Iowa State Cyclones.  

Purdue led by as many as 19 points in the second half, taking a 58-39 advantage with 14:24 left to play. It would evaporate when Iowa State went on a 34-13 run over the next 11 minutes to take a two point lead. 

The Boilermakers responded by scoring the next seven points and wouldn't trail again. Caleb Swanigan made a game-saving play with a rebound following Dakota Mathias' missed free throw on the front end of a one-and-one, via NCAA March Madness:

Swanigan, not surprisingly, was all over the court for Purdue. The sophomore sensation recorded his 28th double-double this season with 20 points and 12 rebounds. Vince Edwards joined his teammate on the double-double train with 21 points and 10 rebounds. 

Iowa State fought valiantly on the strength of Deonte Burton, Matt Thomas and Monte Morris combined for 63 of the team's 76 points. The Cyclones' lack of size played an instrumental role in defeat, as they were outrebounded 39-27 by Purdue. 

Purdue will play in the second weekend of the NCAA tournament for the first time since 2010.
