Here's when all perfect brackets busted in the 2022 NCAA men's and women's tournaments

No. 10 Creighton knocks off No. 2 Iowa

And then there was one. No. 10 Creighton's 64-62 defeat of No. 2 Iowa busts two brackets leaving only one to survive. ESPN user “GO VOLS! GBO!" is the last standing perfect women's bracket. 

Here’s what they picked for the rest of Sunday’s games:

• No. 4 Maryland vs. No. 12 Florida Gulf Coast — Maryland 
• No. 1 South Carolina vs. No. 8 Miami (Fla.) — South Carolina 
• No. 2 Texas vs. No. 7 Utah — Utah

• No. 1 Louisville vs. No. 9 Gonzaga — Gonzaga 
• No. 3 Iowa State vs. No. 6 Georgia — Georgia 
• No. 1 Stanford vs. No. 8 Kansas — Stanford 

Two of the remaining brackets picked No. 2 Iowa to advance past Sunday

Over 1 million women's brackets are down to just three. Two survived from ESPN and one from CBS. As we track the quest for the perfect bracket here's what each challenger picked for Sunday through the first four games:

1. "GO VOLS! GBO!" on ESPN

• No. 2 Iowa vs. No. 10 Creighton — Creighton
• No. 4 Maryland vs. No. 12 Florida Gulf Coast — Maryland

Following two thrillers with higher seeds No. 3 LSU and No. 5 Oregon on severe upset alerts — No. 12 Belmont took down the Ducks — only six brackets are still perfect among the major online women's bracket games. We're following more than 1 million brackets on the Women's Bracket Challenge Game, ESPN and CBS.

No. 14 seeds are now 0-112 all-time against No. 3 seeds, though Jackson State rallied from down 17 down in the third quarter to take a 74-64 lead. However, LSU then stormed back to escape 83-77 thanks to Khayla Pointer's 26 points and a clutch 3-pointer late.

Later, Belmont upset Oregon as the Bruins advanced to the second round as a No. 12 seed for the second year in a row. Belmont's Tuti Jones posted 22 points, six rebounds and four steals in the win.

No. 11 Princeton's 69-62 upset of No. 6 Kentucky took a big bite out of the perfect brackets, leaving only 24 alive among the major online bracket games: Women's Bracket Challenge Game, ESPN and CBS. We have been tracking more than 1 million brackets across these games.

The Tigers' win dropped the total down to 24 from 81. It also eliminated the final WBCG bracket.

Here's the running counter, through 26 games:

• ESPN: 15
• CBS: 9
• WBCG: 0

We'll see how much longer our remaining flawless brackets can go.

NO. 3 IOWA STATE WINS FIRST MATCHUP

One day into the women's round of 64 and hundreds of thousands of brackets are busted. Only 28 are flawless in our Bracket Challenge Game after No. 3 Iowa State finished off No. 14 UT Arlington.

Here's how the early games could shake up the remaining perfect brackets:

• If (8) Washington State beats (9) Kansas St. — 6 brackets 
• If (9) Kansas St. wins — 22 brackets 
• If (6) BYU defeats (11) Villanova — 15 brackets
• If (11) Villanova wins — 13 brackets

No. 11 Iowa State beat No. 6 LSU Friday.

There will be no perfect men's bracket this year.

With No. 11 Iowa State's 59-54 upset win over No. 6 LSU, the final perfect bracket of the 2022 basketball tournament — created by ESPN user "Bekins24" — was busted.

It took 28 games to eliminate the last perfect bracket. Entering Friday, there were 192 perfect brackets across the major games, Men's Bracket Challenge Game, ESPN, CBS and Yahoo. 

Here's how many perfect brackets remained after each game:

• No. 7 Ohio State 54, No. 10 Loyola 41 — 91 perfect brackets
• No. 2 Auburn 80, No. 15 Jacksonville State 61 — 81
• No. 3 Texas Tech 97, No. 14 Montana State 62 — 63
• No. 3 Purdue 78, No. 14 Yale 56 — 47
• No. 2 Villanova 80, No. 15 Delaware 60 — 42
• No. 10 Miami 68, No. 7 USC 68 — 18
• No. 11 Notre Dame 78, No. 6 Alabama 64 — 4
• No. 6 Texas 81, No. 11 Virginia Tech 73 — 2
• No. 2 Duke 78, No. 15 Cal State Fullerton 61 — 2
• No. 4 Illinois 54, No. 13 Chattanooga 53 — 1
• No. 1 Arizona 87, No. 16 Wright State 70 — 1
• No. 11 Iowa State 59, No. 6 LSU 54 — Zero

This marks the second year in a row the chase for perfection ended on the second day of the first round. But in 2019, Gregg Nigl correctly picked the first 49 games.

At the opening tip of the first round, there were more than 20 million men’s brackets in the major online games — the Men’s Bracket Challenge Game, CBS, ESPN and Yahoo.

Now, 26 games into the 2022 NCAA men’s basketball tournament, just one perfect bracket remains after No. 4 Illinois rallied to beat No. 13 Chattanooga 54-53. Click or tap here to check out the final perfect bracket on ESPN.

There were only 192 brackets across the four major games after Thursday's 16 games thanks to a flurry of upsets and overtime games. Here are the biggest bracket busters which brought us down to one, beginning with the 15-over-2 stunner of Saint Peter's beating Kentucky:

• No. 15 Saint Peter’s 85, No. 2 Kentucky 79 (OT) — Fewer than 1,000 perfect brackets remained after this one. A 15-over-2 upset had happened just nine other times in NCAA tournament history. Saint Peter’s made it 10. The Peacocks were picked to win the first round in less brackets (3.04 percent) than Kentucky was picked to win the national championships in the Men's Bracket Challenge Game (6.01 percent).
• No. 7 Ohio State 54, No. 10 Loyola 41 — There were 192 perfect brackets entering Friday. After the first game, only 91 remained.
• No. 11 Notre Dame, No. 6 Alabama 64 — Notre Dame, less than two days after its double-overtime win over Rutgers in the First Four, beat Alabama and brought the number of perfect brackets from 18 down to four.
• No. 4 Illinois 54, No. 13 Chattanooga 53 — Illinois' win knocked out the second-to-last perfect bracket.

ESPN user "Bekins24" has the only remaining perfect bracket. Here's who they have through the remainder of Friday's games, along with their Final Four, championship and national champion picks:

• No. 6 LSU vs. No. 11 Iowa State — LSU
• No. 5 Houston vs. No. 12 UAB — Houston
• No. 7 Michigan State vs. No. 10 Davidson — Davidson
• No. 3 Wisconsin vs. No. 14 Colgate — Wisconsin
• No. 8 Seton Hall vs. No. 9 TCU — TCU
• Final Four — Gonzaga, UCLA, Houston, Providence
• Championship — Gonzaga vs. Houston
• National Champion — Houston

Last year, perfect brackets remained into 28 games. In 2019, Gregg Nigl correctly picked the first 49 games.

No. 6 Texas beat No. 11 Virginia Tech Friday.

And then there were two.

Of the more than 20 million combined men's brackets submitted in the the major online games of the Men's Bracket Challenge Game, ESPN, CBS and Yahoo, only two remain perfect following No. 6 Texas' 81-73 win over No. 11 Virginia Tech.

There are still eight games remaining in Friday's action. Here's who the two remaining perfect brackets, which have agreed through the first 24 games, have winning each game:

• (4) Illinois vs. (13) Chattanooga — Illinois (one), Chattanooga (one)
• (2) Duke vs. (15) Cal State Fullerton — Duke (both)
• (6) LSU vs. (13) Iowa State — LSU (one), Iowa State (one)
• (1) Arizona vs. (16) Wright State — Arizona (both)
• (5) Houston vs. (12) UAB — Houston (both)
• (7) Michigan State vs. (10) Davidson — Michigan State (one), Davidson (one)
• (3) Wisconsin vs. (14) Colgate — Wisconsin (both)
• (8) Seton Hall vs. (9) TCU — TCU (both)

No. 2 Baylor blows out No. 15 Hawaii

No. 2 seeds Iowa and Baylor both blew out their No. 15 opponents by 40 points. That slightly dropped the Women’s Bracket Challenge perfection percentage to 0.36%. 

The Hawkeyes and Bears are both heavily chosen to make it deep in the tournament. 

Sweet Sixteen — Baylor 94.79%, Iowa 95.40%
Elite 8 — Baylor 87.44%, Iowa 86.93%

No. 10 Miami beat No. 7 USC Friday.

With No. 10 Miami's 68-66 thrilling victory over No. 7 USC, the last two perfect brackets remaining in the Men's Bracket Challenge Game have been busted. No. 2 Villanova's win over No. 15 Delaware eliminated the last remaining perfect bracket on CBS.

Just 18 perfect brackets remain across the major games — 17 on ESPN and one on Yahoo.

There were 192 perfect brackets remaining this morning. After the first four games, just 47 remained. Here's how Villanova's and Miami's wins eliminated the remaining brackets:

• (2) Villanova 80, (15) Delaware 60 — 42 perfect brackets remained.
• (10) Miami 68, (7) USC 66 — 18 brackets.

While Villanova was a heavy favorite in brackets, USC held the slight edge over Miami in all four bracket games. Here's the percentage of brackets which had USC advancing:

• MBCG — 50.62 percent
• ESPN — 55.2 percent
• CBS — 56 percent
• Yahoo — 57.05 percent
