Jewell Loyd scored 18 of her 26 points in the second half, and No. 2 Notre Dame capped its perfect first run through the Atlantic Coast Conference by beating No. 10 Duke 69-53 on Sunday night in the league tournament final.
Kayla McBride added 25 points to help the top-seeded Fighting Irish (32-0) — last year's Big East champions — win their second consecutive conference tournament and extend the best start in school history with their third victory over the Blue Devils in five weeks.
Haley Peters had 18 points and Elizabeth Williams finished with 17 points and 16 rebounds for the second-seeded Blue Devils (27-6), who shot 44 percent but had 20 turnovers.
They reached the ACC title game for the sixth time in seven years under coach Joanne P. McCallie, but were denied their second straight championship and fell to 1-9 in the series.
Duke's best chance to claw back into the game came when Ka'lia Johnson went to the line with her team down 10 with 2:23 left.
But she missed the front end of a one-and-one, McBride followed with two free throws, and after a turnover, Loyd hit a fast-break layup to put Notre Dame up 65-51 and send the Irish on their way to their seventh tournament title in their third different league. They won what's now known as the Horizon League six times before winning the Big East on their way out of that conference.
Ultimately, the two Blue Devils most capable of keeping up with Loyd — guards Chelsea Gray and Alexis Jones — were on the bench in sweats with season-ending knee injuries.
Loyd, who averaged 19 points in the two previous wins over Duke, had a hand in six of the nine baskets during a 19-4 run early in the second half that put Notre Dame in control.
No. 16 Nebraska 72, No. 23 Iowa 65: Rachel Theriot scored 19 of her 24 points in the second half Sunday, leading No. 16 Nebraska past No. 23 Iowa for the Big Ten tournament title.
It's the first time the Cornhuskers (25-6) have ever won a conference tourney crown, clinching the league's automatic NCAA tournament bid. Nebraska also posted its second straight 25-win season and is tied for the second most victories in school history. The Cornhuskers head into the postseason with plenty of momentum after winning 12 of 13.
Iowa (26-8) was led by Ally Disterhoft with 20 points and Samantha Logic with 14 but had a six-game winning streak snapped.
Nebraska never trailed, though Iowa closed to 57-56 with 7:43 to play. Theriot, the tourney's most outstanding player, helped Nebraska pull away with an 8-3 run.
No. 25 DePaul 78, Georgetown 54: Megan Rogowski and Megan Podkowa scored 17 points apiece as top-seeded DePaul beat No. 8 seed Georgetown in a Big East tournament quarterfinal matchup on Sunday.
Rogowski made three 3-pointers and Podkowa hit 5 of 8 shots for DePaul (25-6). Jessica January added 11 points.
Georgetown held an early 18-14 lead before DePaul went on an 11-0 run, seven by Podkowa, for a 25-18 lead. DePaul scored the final six points of the half to lead 33-22.
Then Rogowski started and capped a 10-0 run with 3-pointers for a 43-22 advantage and DePaul led by double-digits the entire second half.
DePaul converted 24 of 24 free throws, while Georgetown hit just five of their 10 attempts.
No. 2 Wichita St. 83, Indiana St. 69: Fred VanVleet scored 22 points including several key baskets late to lead another strong ensemble effort and No. 2 Wichita State remained the nation's lone unbeaten after defeating Indiana State in the Missouri Valley Conference tournament final.
Tekele Cotton added 20 points — with four 3-pointers — and Ron Baker had 14 points for the Shockers (34-0), who got tested in the second half before putting the title game out of reach with a 13-0 run capped by two 3-pointers from VanVleet that put them up by 18 points with 5:38 to go.
Wichita State matched the NCAA record for victories to start the season held by UNLV in 1990-91 with its third straight convincing tournament win after going 18-0 in the conference regular season. The Shockers won their first conference tournament since 1987.
Manny Arop and Justin Gant had 18 points apiece for second-seeded Indiana State (23-10), which has one of the closer calls against Wichita State with a seven-point loss at home in early February.
Northwestern 74, Purdue 65: Drew Crawford had 27 points and seven rebounds and Alex Olah added 14 points and seven rebounds to lead Northwestern over Purdue in the regular season finale for both teams.
The Wildcats (13-18, 6-12 Big Ten), who snapped a league-worst seven-game skid, closed out the first half on a 6-2 run to take a 28-21 lead at halftime. Northwestern went on a 9-2 run midway through the second half capped off with a 3-pointer by Sanjay Lumpkin with 11:17 remaining for a 45-32 lead.
Rapheal Davis had 13 points and nine rebounds and A.J. Hammons added 13 points for the Boilermakers (15-16, 5-13), who have lost six straight.
The Big Ten Tournament opens on Thursday in Indianapolis.
Ohio St. 69, No. 22 Michigan St. 67: LaQuinton Ross scored 22 points and Aaron Craft added 12, including a late free throw, to lead Ohio State past No. 22 Michigan State.
Keith Appling's jumper with 2 seconds left was off the mark for the Spartans, who failed to score over the final 4:30 as Ohio State scored the game's final four points.
Adreian Payne scored 23 points, Gary Harris had 12 and Denzel Valentine 11 for the Spartans (23-8, 12-6 Big Ten), who have lost seven of their last 11.
Much-maligned center Amir Williams hit a free throw with 37.2 seconds left to put Ohio State (23-8, 10-8) ahead for good. Craft then added a free throw with 20.9 seconds remaining.
Both teams were seeking some traction heading into the postseason. The Buckeyes had dropped their last two on the road to second-tier Big Ten teams.
