March Madness 2026 live bracket updates: No. 1 Duke survives near upset by No. 16 Siena; No. 12 High Point topples Wisconsin; Ohio State falls to TCU

The 2026 NCAA Tournament has kicked off with the kind of heart-pounding drama that defines March Madness. In a slate of games that kept fans on the edge of their seats, top-seeded Duke narrowly avoided becoming the second No. 1 seed in history to fall to a No. 16, while the traditional "12-over-5" upset was realized by a resilient High Point squad. Meanwhile, the TCU Horned Frogs delivered a clinical performance to send Ohio State packing early, proving once again that rankings mean little once the ball is tipped in the Big Dance. As the bracket busts across the country, we bring you the most comprehensive live updates and analysis of these foundational Round of 64 matchups.

Featured Snippet: March Madness 2026 Key Results
In the opening round of the 2026 NCAA Tournament, No. 1 Duke survived a massive scare from No. 16 Siena, winning 74-72 after a last-second block. The biggest bracket buster of the day saw No. 12 High Point upset No. 5 Wisconsin 68-63, marking a historic win for the program. Additionally, No. 11 TCU defeated No. 6 Ohio State 81-75, continuing the trend of lower-seeded teams dominating the early sessions of the tournament.

Duke vs. Siena: A Brush with Historical Disaster

Duke entered the tournament as one of the favorites to cut down the nets, but for forty minutes in Greenville, the Blue Devils looked anything but dominant. Facing a No. 16 seeded Siena team that played with absolute fearlessness, Duke found themselves trailing by five points with less than four minutes to play. Siena’s perimeter shooting was unconscious, hitting 12 three-pointers that silenced the heavily pro-Duke crowd. However, veteran leadership eventually took over as Duke utilized a 10-2 run to reclaim a late lead. A desperate Siena layup at the buzzer was swatted away, allowing the Blue Devils to escape with a 74-72 victory. While they survive to play another day, questions about their defensive rotations and ability to handle high-pressure underdog scenarios will persist into the Round of 32.

High Point Makes History: The 12-5 Upset Lives On

The "12-over-5" upset is a staple of March Madness lore, and in 2026, High Point University etched their name into that history. Taking on No. 5 Wisconsin, High Point used a sophisticated motion offense and a lockdown zone defense to frustrate the Badgers from the opening tip. Wisconsin, known for their disciplined play, struggled to find a rhythm against High Point's length and athleticism. The Panthers led for nearly 30 minutes of the contest, resisting every Wisconsin surge. With the score tied at 60-60 late, High Point connected on back-to-back transition buckets to seal the 68-63 upset. This victory represents the first NCAA Tournament win in High Point's program history, sparking celebrations that will likely last all weekend.

TCU Dominates Ohio State in Mid-Seed Clash

In a matchup between two physical programs, No. 11 TCU proved to be too much for No. 6 Ohio State. The Horned Frogs brought a Big 12 intensity that the Buckeyes simply couldn't match in the paint. TCU out-rebounded Ohio State by a margin of +12, turning second-chance opportunities into a constant stream of points. Despite a late rally led by Ohio State’s backcourt, TCU’s poise at the free-throw line in the final minute secured an 81-75 win. The loss is a disappointing exit for an Ohio State team that had high hopes following a strong finish in the Big Ten, but for TCU, it’s a statement win that sets up a fascinating second-round encounter.

Analysis: Why the Blue Devils Struggled Against Siena

Duke's narrow escape highlights a growing trend in college basketball: the narrowing gap between elite talent and experienced, mid-major systems. Siena started four seniors, a contrast to Duke’s rotation which relies heavily on freshmen and sophomores. The Blue Devils struggled with Siena's ball screens and were frequently beaten on backdoor cuts. Duke’s coaching staff will need to address these defensive lapses immediately. If a No. 16 seed can exploit these holes, higher-seeded opponents in the later rounds will certainly do the same. The "survival" mindset is fine for now, but Duke needs to rediscover the defensive identity that won them the ACC Tournament if they want a deep run.

Matchup	Final Score
No. 1 Duke vs. No. 16 Siena	74-72
No. 12 High Point vs. No. 5 Wisconsin	68-63
No. 11 TCU vs. No. 6 Ohio State	81-75
No. 8 Kentucky vs. No. 9 Michigan State	79-77 (OT)

High Point’s Blueprint for the Upset

How did High Point do it? It came down to two factors: three-point efficiency and turnover margin. High Point shot 45% from beyond the arc, while forcing Wisconsin into 14 turnovers. The Panthers played a style that minimized Wisconsin's size advantage by stretching the floor and forcing the Badgers' big men to defend on the perimeter. This game serves as a masterclass for mid-major programs on how to dismantle a Power 5 opponent through tactical discipline and fearless execution.

Ohio State’s Early Exit: What Went Wrong?

For Ohio State, the loss to TCU was a failure of execution in the "small things." Missing six free throws in the second half and allowing TCU to grab 15 offensive rebounds proved to be the difference. The Buckeyes' offense became stagnant in the final ten minutes, relying too heavily on isolation plays rather than the ball movement that characterized their regular-season success. Head Coach Chris Holtmann will likely face tough questions regarding the team's preparation for TCU’s physical defensive style.

Looking Ahead: Potential Second Round Matchups

With Duke advancing, they now face a dangerous No. 8 seed in the next round. The scare against Siena may serve as a wake-up call, or it could be a sign of deeper structural issues. High Point will look to continue their Cinderella story against the winner of the No. 4 vs. No. 13 matchup, while TCU enters the second round with a significant amount of momentum. The 2026 bracket is already in shambles for many, and we are only through the first day of action.

The Impact of the 2026 Transfer Portal on Tournament Parity

One cannot discuss the upsets in the 2026 tournament without mentioning the transfer portal. High Point and TCU both featured key starters who transferred from larger programs, seeking more playing time or a better cultural fit. This redistribution of talent is making the early rounds of March Madness more volatile than ever. Mid-majors are no longer just "scrappy teams"; they are often rosters filled with veteran players who have high-level college basketball experience, making them uniquely equipped to take down giants.
