NEW YORK (AP) — James Madison announced itself by beating a Big Ten team to start this season.

When the Dukes did it again to start their NCAA Tournament, they made sure everybody knew: “It’s not an upset,” Xavier Brown yelled, popping his jersey in the middle of the celebration with teammates and in front of the fired-up JMU family section at Barclays Center.

Terrence Edwards Jr. scored 14 points and James Madison became the first 12 seed to advance in this March Madness, beating Wisconsin 72-61 on Friday night.

The Dukes (32-3) will face fourth-seeded Duke on Sunday in the second round of the South Region in Brooklyn, where the JMU fans made themselves right at home.

“Told the team, I’m proud of them, but not surprised,” James Madison coach Mark Byington said.

The Dukes had not been in the tournament since 2013, when they won a First Four game against LIU. Now, they are into the second round for the first time since 1983 — bringing with them a 14-game winning streak that is the longest in the nation.

EAST REGION

#1 Connecticut 91, #16 Stetson 52

Donovan Clingan scored 19 points and Cam Spencer had 15 as top-seeded UConn began defense of its national championship by cruising past 16th-seeded Stetson 91-52.

Stephan Swenson scored 20 points for the Hatters, the ASun champions who were making their first appearance in the NCAA Tournament.

UConn recorded its most lopsided NCAA victory since beating Chattanooga by 56 in the first round of the 2009 tournament.

#13 Yale 78, #4 Auburn 76

Auburn’s Chad Baker-Mazara was ejected for a flagrant 2 foul less than four minutes into the fourth-seeded Tigers’ first-round NCAA Tournament game against No. 13 seed Yale.

Replays showed that Baker-Mazara appeared to throw an elbow toward Yale’s August Mahoney as the pair ran downcourt. Auburn coach Bruce Pearl questioned why officials decided the foul merited an ejection.

He says it was “clearly a flagrant 1” but elevating it beyond that was “a pretty tough call.” Pearl says Baker-Mazara is one of Auburn’s best players and he was clearly missed as the Tigers ended up losing 78-76.

#5 San Diego State 69, #12 UAB 65

Jaedon LeDee dominated inside on the way to 32 points, Lamont Butler added 15 and San Diego State held off 12th-seeded UAB 69-65.

A year after marching to the national title game, also as a No. 5 seed, the Aztecs saw a 12-point second-half lead disappear before putting together a late surge on the strength of their star 6-foot-9 forward. That ensured San Diego State avoided a March Madness surprise.

Efrem Johnson scored 19 points to lead UAB. He had a chance at a tying 3-pointer with 8 seconds left, but it rimmed off.

#9 Northwestern 77, #8 Florida Atlantic 65 (OT)

Ryan Langborg scored 12 of his career-high 27 points in overtime, and ninth-seeded Northwestern finally put away No. 8 seed Florida Atlantic 77-65. The injury-depleted Wildcats recovered after squandering a nine-point lead late in the second half.

Brooks Barnhizer’s driving layup tied it with nine seconds left. Next up for Northwestern is No. 1 overall seed UConn in the second round of the East Region on Sunday in Brooklyn.

Vlad Goldin had 19 points for the Owls, who returned nearly their entire team from a surprising Final Four run last year but were unable to muster that same March magic this time.

And he did it all in 30 minutes while going 11 of 17 from and helping the Boilermakers post a 48-23 rebounding advantage

The Boilermakers tied the school’s single-season record with the their 30th win and can break that mark Sunday against either eighth-seeded Utah State.

Wade Taylor IV led five Aggies in double figures with 25 points as No. 9 seed Texas A&M sent eighth-seeded Nebraska home still looking for its first NCAA Tournament victory after beating the Huskers 98-83 Friday night.

Grand Canyon became the second No. 12 seed to pull a late-night upset after James Madison took down Wisconsin.

The Antelopes did it with style, slashing and shooting their way to expose the No. 2 scoring defense in the country. Grant-Foster was the instigator but he had help. Gabe McGlothan had 12 points and 11 rebounds and Ray Harrison scored 17 points. Mitchell Saxen led Saint Mary’s with 14 points.

Aidan Mahaney added 13, but the regular season and tournament champions of the West Coast Conference were bounced.

Chase Hunter scored 21 points and sixth-seeded Clemson ended No. 11 seed New Mexico’s hopes of repeating the Mountain West’s run in the NCAA Tournament, beating the Lobos 77-56.

The Lobos came in as the Mountain West Tournament champs, a popular pick to be this tournament’s version of San Diego State a year ago. New Mexico was favored by 2 1/2 points in this game, according to FanDuel Sportsbook.

But Clemson dominated on both ends, leading by 19 points in the first half and 23 in the second. Nelly Junior Joseph had 14 points and 12 rebounds for New Mexico.
