Stanford, Maryland, Connecticut and Notre Dame all clinched their places in the women's NCAA Final Four in Nashville.
After having their streak of five consecutive Final Four appearances snapped last year, Stanford sealed their place in college basketball's showpiece event with a 74-65-triumph over North Carolina on Tuesday night.
The game was played at Stanford's Maples Pavilion.
Maryland clinched their spot with a 76-73 victory over Louisville, who lost despite playing in front of their supporters at the KFC Yum! Center in Kentucky.
On Monday, defending champions Connecticut (UConn), who are led by USA women's coach Geno Auriemma, won 69-54 over Texas A&M in Nebraska and Notre Dame, playing at home in South Bend, Indiana, prevailed 88-69 over Baylor.
The celebrations were not as raucous as they might have been at Notre Dame, however, because their Canada international Natalie Achonwa suffered a season-ending knee injury.
The senior had 19 points and 15 rebounds against Baylor but tore her ACL in the second half.
Achonwa, who represented the Canadians at the 2010 FIBA World Championship for Women in the Czech Republic and also played at the 2012 Olympics, has remained upbeat.
After having the severity of the injury confirmed, she tweeted: "HUGE thank you to everyone for their positive thoughts, vibes & prayers! He has a plan for us all... my time will come!"
Achonwa will be with the Irish when they play Maryland on 6 April at the Final Four in Tennessee.
"Natalie has been an extremely valuable contributor to our success, not only this season but throughout her career, and that won't change," Notre Dame coach Muffet McGraw said.
"While she may not be in uniform, her voice will be heard loud and clear in the locker room, on the bench and in the huddle.
"I know that our team is going to continue to feed off her energy, passion and leadership as we head into the Final Four."
Auriemma, whose Huskies will take on Stanford in the other Semi-Final, also went on Twitter to express his angst over Achonwa's injury.
"All other issues aside I was sick to my stomach when I heard about Natalie Achonwa tearing her ACL," he tweeted.
"I've been there and I feel for her."
There are several players who will be at the Final Four who in January were named in the 33-strong USA player pool for 2014-16.
Among them is Maryland forward Alyssa Thomas, who had 23 points, 13 rebounds and three steals in the win over Louisville.
Those wearing the UConn jersey in the USA pool include Breanna Stewart, Stefanie Dolson and Kaleena Mosqueda-Lewis.
Also among those with a chance to make this summer's World Championship squad is Notre Dame guard Kayla McBride.
