LSU is back on top. Honestly, if you didn't see that coming after Jay Johnson reloaded the roster, you weren't paying attention. The 2025 season wrapped up with the Tigers hoisting their eighth national title after a wild June in Omaha, but the road there was a complete mess for anyone trying to predict the field.
The thing about college baseball bracketology 2025 is that the RPI (Rating Percentage Index) continues to be the most loved and hated metric in the sport. It’s basically the gatekeeper. You can have a flashy record, but if your Strength of Schedule (SOS) looks like a mid-major's midweek slate, the committee will bury you. Just ask the teams that got snubbed last May.
The Chaos of the 2025 Field of 64
Predicting the bracket isn't just about picking the best teams; it's about guessing how a room full of people in Indianapolis will value a series win in March versus a collapse in May. Last year, the SEC and ACC didn't just dominate—they practically owned the hosting sites. We saw 16 regional hosts announced on May 25, and the map was heavily tilted toward the Southeast.

Vanderbilt secured a #1 national seed, which felt right until they ran into a buzzsaw. Arkansas, as usual, looked like the most complete team on paper but couldn't quite clear the hurdle. But the real story of the 2025 bracketology cycle was the "Bubble."
The bubble was brutal. Wake Forest, South Carolina, and Texas Tech were all sweating on Selection Monday. Some experts, like Mark Etheridge at D1Baseball, pointed out that midseason projections were already hinting at a massive logjam. When the final bracket dropped, the "First Four Out" included names that would've been locks in any other year. Texas found themselves on the wrong side of the line, which sparked a week of talk radio fury.
Why the RPI Still Rules (and Why It’s Weird)
You've probably heard fans complaining about the RPI. It's a formula that rewards you for playing tough teams, even if you lose a few. In 2025, Coastal Carolina used this to their advantage. They didn't just win; they scheduled aggressively. By the time the tournament started, the Chanticleers had a top-five RPI despite playing in the Sun Belt. It propelled them to a national seed and a deep run to the finals where they eventually fell to LSU.
- LSU's Path: They entered as a #6 seed, proving you don't need to be #1 to win it all.
- The Murray State Shock: A #4 seed in the Oxford Regional that somehow punched a ticket to Omaha. No one's bracket survived that.
- PAC-12 Ghost Effect: With the conference splintered, former PAC teams like Oregon State and UCLA found themselves in new territory. Oregon State, playing as an independent, still managed to host a regional because their metrics were simply undeniable.
What Most People Miss About the Committee
People think the selection committee just looks at the Top 25. They don't. They look at "Q1 wins"—wins against the top 50 in RPI.

If you're a team like Southern Miss or East Carolina, you basically have to be perfect. One bad weekend against a sub-200 RPI team can tank your hosting chances. In 2025, we saw UCLA re-establish themselves by dominating a "weaker" conference schedule but backing it up with massive non-conference wins. It’s a balancing act. You have to win the games you're supposed to win, but you must win at least 40% of the games where you're the underdog.
Looking Toward the 2026 Shift
As we sit here in January 2026, the landscape is already shifting. The preseason rankings are out, and UCLA is sitting at #1. Why? Because they returned eight starters and nearly their entire pitching staff.
But if we learned anything from college baseball bracketology 2025, it’s that January rankings are mostly fiction. The real bracketology starts in April. That’s when the RPI stabilizes and we see who actually has the "Sunday starter" needed to win a regional.
Actionable Insights for Following the Bracket
If you want to track the tournament like a pro instead of just reacting to the news, keep these factors in mind:
- Monitor the Midweek Games: These are trap games. A loss to a local rival on a Tuesday doesn't just hurt the record; it bleeds your RPI score.
- Focus on Road Series Wins: The committee loves teams that can win on the road. A sweep at an SEC or ACC opponent is worth double a home sweep in their eyes.
- Watch the "Kopi" (Conference RPI): If your conference is having a down year, your ceiling is capped. In 2025, the Big Ten's struggles meant their champion was essentially locked into a #3 seed in someone else's regional.
The 2025 season was a reminder that college baseball is the most volatile sport in the NCAA. One bad bounce, one missed call at first base, and a #1 national seed goes home. LSU proved that being "hot" in June matters more than being "perfect" in March.
Keep an eye on the RPI updates starting in late March. That’s when the 2026 bracket will actually begin to take shape, and we'll see if UCLA can handle the target on their back or if another "dark horse" like Murray State is waiting in the wings.
Pro Tip: Bookmark the D1Baseball RPI tracker and check it every Monday morning after conference play starts. It’s the only way to see the bracket the way the committee sees it before the TV cameras turn on.
