For the first time in program history, Texas A&M is the No. 1 seed in the NCAA softball tournament, with the Aggies staving off four-time reigning champion Oklahoma for the honor in Sunday's 2025 bracket drop.

After adverse weather canceled their conference title game on Saturday, the Aggies and No. 2-seed Sooners became 2025 SEC tournament co-champions, leaving the NCAA selection committee to lean heavily on each team's strength of schedule in making their top-seed decision.

"What set apart Texas A&M is they have 19 Top 25 wins, which is number one in the country," said NCAA softball committee chair Kurt McGuffin on Sunday's ESPN2 broadcast, noting the Aggies' tough nonconference schedule.

Taking on a lighter nonconference slate than usual due to massive roster turnover following the 2023/24 season, Oklahoma relied heavily on their record in a stacked SEC, finishing one half-game ahead of A&M in regular-season play.

While the Sooners look to extend their championship streak, the Aggies will be hunting their third national title and first since 1987.

Standing in their way in the 64-team bracket are a record number of familiar foes, as the SEC boasts 14 teams in the 2025 NCAA competition — the most from any single conference in tournament history.

Even more, nine of the bracket's 16 seeded teams hail from the SEC, and a full seven of the Top 8.

Conference champs, at-large teams score NCAA bracket spots

SEC squads aren't the only teams looking to topple Texas A&M and Oklahoma, however, as conference champions and other elite squads learned their tournament fates on Selection Sunday.

No. 5 Florida State is the highest seeded non-SEC team, despite falling 2-1 to No. 11-seed Clemson in Saturday's ACC title game. Along with No. 14-seed Duke, the ACC will see nine teams in the 2025 tournament.

Behind 2024 National Player of the Year NiJaree Canady — the nation's top pitcher — Texas Tech leads a five-team contingent from the Big 12 after securing both their conference tournament trophy and the national No. 12-seed this weekend.

In the weekend's most upset-filled conference tournament, unseeded Michigan outlasted both No. 9-seed UCLA and No. 16-seed Oregon to score a second straight Big Ten tournament title on Saturday, becoming one of eight teams repping the conference in Sunday's bracket.

Notably, the Bruins — the winningest program in NCAA softball history with 12 titles — have not entered the tournament lower than a No. 6 seed since 2016.

The road to the 2025 Women's College World Series begins with Regionals, in which each of the 16 seeded teams will host a four-team double-elimination mini-tournament this weekend.

With a minimum of 96 games — and a possibility of 112 — Regional play begins at 12 PM ET on Friday, with the 64-team field narrowing to 16 by Sunday night.

All games will air live across ESPN's networks.

NCAA conference realignment drastically altered this year's college sports landscape, affecting volleyball, basketball, and, now, softball, as former titans lose ground while others rise to the occasion.

After years dominating the Big 12, four-time reigning NCAA softball champions Oklahoma are now riding the ups and downs of the stacked SEC.

The Sooners recorded a loss to unranked Missouri and fell twice to then-No. 10 Tennessee last month, before dropping two of three games to then-No. 22 Alabama this week.

With the now-No. 17 Crimson Tide's victories, Oklahoma fell two spots to No. 4 in Tuesday's ESPN/USA Softball rankings update.

Similarly, after adding a pair of weekend losses to then-No. 5 Tennessee alongside earlier stumbles against ranked SEC foes Florida and Mississippi State, former Big 12 standout No. 1 Texas took a tumble, with the 2024 runners-up Longhorns sliding to No. 3 this week.

While those wins earned the Vols a boost to No. 2, a dark horse SEC squad took over the sport's No. 1 spot on Tuesday, when a 12-game winning streak lifted the Texas A&M Aggies atop both the SEC table and the national rankings for the first time in program history.

SEC solidifies itself as top NCAA softball conference

The fall of NCAA softball's recent giants from the sport's elite spots isn't due to a decline in Oklahoma's or Texas's play, but simply a result of the intense level of competition and talent in the SEC.

The conference now lays claim to all of NCAA softball’s top four teams — plus seven of the Top 10.

With the college softball postseason looming next month — not to mention the eight-team Women's College World Series beginning on May 29th — the SEC is proving itself the conference to beat in the 2025 title hunt.

While No. 1 Texas A&M will take the weekend off after closing out a three-game series against Missouri early Friday afternoon, both No. 3 Texas and No. 4 Oklahoma will be battling in SEC series.

The Longhorns hope to sweep No. 9 LSU after claiming a 7-3 series-opening win on Thursday. Friday's first pitch between the pair is at 5:30 PM ET on SECN+, with Saturday's final game beginning at 12 PM ET on ESPN2.

The Sooners will kick off their own three-game slate against No. 15 Mississippi State at 5 PM ET on Friday, streaming live on SoonerSports. The pair will close out the series with a Sunday doubleheader beginning at 3 PM ET, with both games airing on SECN+.
