The debate has become one of college baseball’s annual postseason traditions, especially on social media: Should host teams “pitch on” or “pitch off” in the NCAA Tournament?
In other words, should college baseball teams stick with their regular rotation, or adjust it for an opening matchup against the regional’s lowest seed?
The logic behind pitching off is straightforward. As a No. 1 seed, you’re heavily favored to win the opener. Since 2021, top seeds own a sparkling 70-10 record in 1-vs-4 regional openers. So why not save your ace for a tougher winner’s bracket matchup?
But recent data shows that approach doesn’t meaningfully alter a team’s postseason fate.
What The Data Says
An analysis of national seeds from the last five NCAA Tournaments reveals minimal difference. Of the 80 national seeds since 2021, 49 chose to adjust their rotation and 31 did not. The teams that altered their order advanced to at least the super regional round 63.3% of the time. Those that stuck with their regular rotation advanced at a 61.3% clip.
In short: whether you pitch on or pitch off, the macro-level results are nearly identical.
That’s a useful counter to the polarized nature of the “pitching off” debate. There’s no magic bullet. There’s no clear strategic edge. And the numbers do not support the notion that changing rotation order, by itself, significantly improves or worsens a national seed’s postseason fate.
Still, context matters. And that’s where the more nuanced insights become even more interesting.
Why Coaches Still Pitch Off
In conversations with several Division I head coaches who have faced this decision since 2021, there are two primary reasons that drive their decisions.
The first and most obvious is matchup-based strategy.
Coaches may look ahead and opt to save their ace for the presumed No. 2 seed, believing their top-seeded roster can handle the No. 4 seed without needing its top arm.
Florida followed this model during its 2023 College World Series run, starting Sunday arm Jac Caglianone in its regional opener against Florida A&M while saving ace Brandon Sproat for game two against Texas Tech.
The second is internal team dynamics—riding the hot hand.
Mississippi State’s 2021 national championship team reshuffled its rotation in the postseason, giving the ball to Will Bednar—who would go on to win College World Series Most Outstanding Player—in its opener rather than typical Friday starter Christian MacLeod.
Why?
“I always believed in putting your best guy in the first game,” former Mississippi State coach Chris Lemonis told Baseball America. “I know what the numbers say about the No. 1 seed beating the No. 4 seed in that game, but you sure as heck don’t want to lose it either. Then your guys start pressing and things fall apart quick.”
The Risks Of Rolling The Dice
Lemonis’ view proved prescient this year.
The 2025 tournament produced the most one-seed opening-game upsets in the post-COVID era. Of the seven hosts eliminated in their own regionals this season, six chose to pitch off and three of those teams lost their opening game outright and never recovered.
That highlights one of the central tensions in the pitching-off decision.
While hosts overwhelmingly win the one-four game, the downside risk of losing it is disproportionate. When that loss occurs, it tends to unravel the entire weekend—especially for teams that have already burned their ace-saving plan.
Another layer of insight for coaches comes from College World Series performance.
Of the 37 national seeds from 2021-24 who altered their rotation, 13 reached Omaha. Nine of the 27 who kept their rotation intact made it as well. Again, not a large gap. But two of the three national champions in that span did not alter their rotation.
That’s not necessarily causal, but it is instructive.
Teams with elite frontline arms—like LSU’s 2023 group featuring Paul Skenes and Ty Floyd—typically benefit from rhythm and stability, not manipulation. There’s little incentive to reshuffle with Skenes at the front of a rotation.
It also suggests a subtle hierarchy of risk-reward. Pitching off may help teams navigate tricky regionals, but true national title runs tend to correlate with consistency.
Yes, Context Matters
Ultimately, the data leaves room for nuance and individualization. There is no universal right or wrong answer. The choice depends on the strength of the No. 4 seed, the depth of the host’s rotation and the team’s psychological makeup.
A national seed with three quality starters may pitch off with little downside. A team with a dominant ace might be better served keeping its rotation order.
There’s also some evidence that the type of rotation adjustment matters. Teams saving an ace purely for a matchup often fare better than those making reactive decisions in the aftermath of a conference tournament or a tired staff.
The broader lesson? The data shows that altering rotation order is not a major driver of postseason outcomes. The why in this case matters much more than the whether.
