While NCAA basketball's Power Four conference tournaments wrapped up on Sunday, teams from mid-major Division I leagues are still battling for invites to the Big Dance, where they'll aim to upset top March Madness contenders.

Already harnessing upset momentum is former Pac-12 squad Oregon State, who won the West Coast Conference (WCC) tournament as the No. 4 seed on Tuesday.

After conference realignment saw most of the starters from last season's Elite Eight team transfer to Power Four programs, Oregon State finished the 2024/25 regular-season at 16-15 (12-8 in WCC play).

This week, however, the Beavers found another gear, tearing through their tournament and upsetting the two WCC regular-season co-champions along the way.

Oregon State paves a path to NCAA tournament underdog

First, Oregon State narrowly defeated top-seeded Gonzaga 63-61 in Monday's semifinals, before beating back-to-back defending champion No. 2-seed Portland 59-46 in Tuesday's tournament finale — only the fourth loss suffered by the Pilots all season.

Oregon State's unlikely March Madness bid is the program's 13th overall, and the ninth in the NCAA tournament's last 11 editions.

"I'm just so happy and so proud of this team," said Oregon State head coach Scott Rueck. "For this group to cover the ground that they did this year, from day one until now, is absolutely remarkable. It's one of the most special things I've been a part of."

The Beavers’ surge, however, holds consequences for both Portland and Gonzaga, whose slim chances of making Sunday's bracket now rest with the NCAA selection committee.

While Portland is a more recent contender on the national stage, Gonzaga hasn't missed an NCAA tournament since 2016, with the Bulldogs appearing in all but two brackets since their 2007 March Madness debut.

NCAA underdogs looks to spur chaos in March Madness

Should they make the cut, at-large underdogs Portland and Gonzaga would join Oregon State and other smaller conference champions in trying to bust brackets by upsetting top contenders in the first few rounds of the NCAA's competition.

Other mid-major standouts are already considered likely members of the 68-team national pool, with current projections listing Fairfield University (Metro Atlantic Athletic Conference) and new No. 24-ranked South Dakota State (Summit League) claiming seeds as high as No. 9.

Projections also show that the Ivy League is on the precipice of sending a full trio of upset-hungry teams to the NCAA tournament.

While regular-season champion Columbia is expected to claim a national No. 11 seed after Saturday's conference tournament final, strong seasons from both Princeton and Harvard have the pair currently snagging one of the final four at-large bracket spots.

Atlantic 10 tournament victors George Mason could also pose a threat to Power Four contenders, with the Patriots clinching their first-ever NCAA tournament berth on Sunday despite ceding the regular-season conference title to Richmond.

Though it’s not always wise to bet against heavyweights in the NCAA tournament's opening rounds, emerging college basketball underdogs are embracing the spotlight — and welcoming the opportunity to shake things up after Selection Sunday.
 
 

With half of the Elite Eight now set, a few Big Ten underdogs still have a shot at disrupting the No. 1 seed stronghold at the 2025 NCAA volleyball tournament this weekend.

The No. 3-seed Purdue Boilermakers are through to the quarterfinals after defeating No. 2-seed SMU 3-1 on Thursday, while the No. 4-seed Indiana Hoosiers, No. 3 seed-Wisconsin Badgers, and the still-undefeated overall No. 1 seed Nebraska Cornhuskers all face stiff Sweet Sixteen competition on Friday afternoon.

Coming off a strong regular season, the Big Ten could still field half of the quarterfinal round — though that would require the first No. 1-seed upset of the 2025 national tournament in the form of an Indiana victory over top-seeded Texas.

Bolstered by their defensive leader, senior middle blocker Madi Sell, the Hoosiers booked just their second-ever Sweet Sixteen trip with last week's win over No. 5 Colorado, with Indiana now hoping their lucky run continues against the 2022 and 2023 champion Longhorns.

Meanwhile, the No. 1 Huskers will look to keep rolling against No. 4-seed Kansas while the No. 3 Badgers aim to snag another Big Ten spot in the Elite Eight by ousting No. 2-seed Stanford on Friday.

The NCAA volleyball tournament's Sweet Sixteen action will wrap with four games on Friday, starting with No. 1 Texas vs. No. 4 Indiana at 12 PM ET.

The Elite Eight will then meet at the net on Saturday and Sunday to determine the last-standing teams heading to next week's Final Four in Kansas City.

All of this weekend's NCAA tournament games will air live across ESPN platforms.

Team USA is on a roll, officially taking the four-game 2025 Rivalry Series against Canada before the slate of friendlies is even over, with the US collecting three consecutive wins so far — and one shot left at making it a clean sweep.

The US downed their northern neighbors by a commanding 10-4 scoreline in Edmonton on Wednesday, marking Team USA's first-ever 10-goal victory against the reigning Olympic champs — all while upping the 2025 series' goal tally to 20-6.

While each team fine-tunes rosters ahead of the 2026 Olympics, one test remains for both international hockey titans before the Winter Games take the ice in February.

"The work doesn't stop. Our Olympic team is not named. There's still one more game to go," said USA captain Kendall Coyne Schofield, acknowledging that her squad is not taking their foot off the gas despite the recent lopsided results.

"We have one more game against them before the Olympics," echoed Canada captain Marie-Philip Poulin. "We're all aware of that."

The puck drops on the final match of the sixth annual hockey Rivalry Series between the USA and Canada in Edmonton, Alberta, on Saturday.

Live coverage of the clash will begin at 9 PM ET on the NHL Network.

The latest FIFA women's soccer rankings dropped on Thursday, with Spain widening their lead at No. 1 after winning a second consecutive UEFA Nations League title earlier this month.

The USWNT held steady at No. 2, ceding 7.48 points after losing an October friendly to No. 22 Portugal before going on to secure four straight wins over Portugal, No. 35 New Zealand, and No. 13 Italy to close out 2025.

Elsewhere in the FIFA Top 10, No. 3 Germany and No. 6 Brazil both saw boosts after successful fall runs, while Canada skidded to No. 10 amid a recent five-match winless streak, with Les Rouges's last victory coming against No. 43 Costa Rica last June.

The biggest changes, however, occurred outside the top ranks, as No. 96 Nicaragua, No. 118 Burkina Faso, and No. 137 American Samoa all rose by 16 spots.

Notably, upcoming USWNT opponent Paraguay saw the largest drop in this month's Top 50, sliding five spots to No. 46.

Ultimately, as the USWNT battled to keep pace in a year of roster experimentation — and without a major competition on the team's 2025 docket — the many international competitions in Europe benefitted victors and challenged losers in this week's FIFA rankings update.

The No. 16 USC Trojans are gearing up for another top-ranked test, hosting the reigning national champion No. 1 UConn Huskies in the weekend's flashiest NCAA women's basketball matchup on Saturday.

Coming off their second ranked win of the season, USC topped No. 20 Washington 59-50 last Sunday, with 22 points and 12 rebounds from freshman Jazzy Davidson helping pull the Trojans to a 7-2 record.

"I saw a resolve in our team," said head coach Lindsay Gottlieb afterwards. "I knew we could get the next stop, I knew we could get the next play."

USC will face a particularly familiar foe against the Huskies — this time without sidelined star junior JuJu Watkins — after UConn knocked the Trojans out of the NCAA tournament two years in a row.

Notably, sophomore guard Kayleigh Heckel departed USC over the summer for the Huskies, with the former Trojan averaging 7.7 points per game entering Saturday's clash with her old team.

"I just try to take one game at a time, but I'm excited to go back," Heckel said ahead of her first trip back to LA since transferring. "I had a great freshman year there, and I learned a lot, and it was a great experience, a lot of fond memories. So I'm looking forward to it."

The Trojans will host the Huskies with tip-off set for 5:30 PM ET on Saturday.
