MLB bringing major rule change experiments to the minor leagues in 2026

Moving second base? Dramatic checked-swing adjustments? Crackdowns on batter timeouts and PitchCom chicanery?

A number of fascinating rule change experiments are coming to the minor leagues in 2026, in accordance to a memo obtained by TheAthletic After it was despatched by Major League Baseball to all 30 golf equipment final week. Details of the memo had been first reported by FanGraphs.

Many of the new 2026 guidelines are sure to increase eyebrows, not to point out the blood stress of minor-league managers and executives. But not like the pitch clock and ball-strike problem system, which additionally started as minor-league experiments, there isn’t a assure you’ll ever see any of those adjustments at a major-league ballpark close to you.

For almost a decade now, MLB has used the minor leagues as a take a look at lab for all kinds of concepts — some sport-changing, some that had been shortly deserted. The 2026 adjustments are seen as experimental, not inevitable. But in participant growth departments throughout baseball, officers are already scrambling to educate gamers and employees on what they’re about to encounter.

The minor-league adjustments will probably be unfold out, and utilized in a different way, amongst completely different leagues and ranges of the minors. Here is what these numerous leagues will probably be working by means of:

Moving second base

Did you already know that for greater than 100 years, second base has been situated in the improper place? True story. Despite what you discovered in Little League, second base has by no means been 90 toes from first or third base, mainly as a result of it flunked geometry.

Confused but? Here’s the deal: Imagine the infield as a wonderfully symmetrical diamond. If you then draw an imaginary line round the infield, first base and third base are in the good spot, in their respective corners of that diamond. Second base, on the different hand, is not.

Basically, it is midway inside and midway outdoors that imaginary diamond. So that is about to change — in the International League, at the very least.

Beginning in the second half of the season, the second-base bag will transfer to its rightful spot in the nook of the imaginary diamond. That means it will likely be nearer to residence plate, however extra importantly, it can even be about 9 inches nearer to each the first-base and third-base luggage — and 13 1/2 inches nearer than it was earlier than rule adjustments elevated the measurement of the bases.

“Original” distance — 88 toes, 1 1/2 inches
Distance with bigger bases — 87 toes, 9 inches
“New” distance — 87 toes

We wrote far more extensively about all of this 4 years in the past, the first time the sport experimented with this change in the minors. If you are curious, you possibly can learn extra about why second base wound up in the improper place here.

What’s the aim? Three years in the past, MLB launched rule adjustments designed to encourage massive leaguers to begin stealing extra bases. It labored nice — for some time. But final yr, the league noticed a lower in stolen-base makes an attempt and success fee. So the hope, clearly, is that if the distance between the bases will get shorter, it can rev up the operating sport once more. But that is not the solely experiment being trotted out with that aim in thoughts.

Fewer disengagements

Once once more, this change is about making an attempt to get these base stealers shifting once more.

In the massive leagues, nothing will change. So pitchers nonetheless have two disengagements per batter. That interprets to two pickoff throws, or some mixture of stepping off the rubber or throwing to a base. If they do {that a} third time, it is a balk, except the runner is thrown out.

But beginning with Opening Day, in the three Double-A leagues — the Eastern, Midwest and Southern Leagues — pitchers will probably be allowed to use solely one disengagement as a substitute of two. So it can now be a balk on the second pickoff transfer in the event that they fail to throw out the runner.

What’s the aim? Again, you already know what followers actually like? Base stealing. So what’s the finest approach to get extra of it into the sport? MLB is making an attempt to determine that out. What it would not know is which rule change is most definitely to encourage extra base stealing — a shorter pickoff restrict/disengagement leash or a shorter distance between bases. So it can unleash each of these experiments at completely different ranges of the minors — and see what it may be taught.

High-tech checked-swing guidelines

Let’s sum up the rule on checked swings: Um, there really isn’t any rule, so the umpiring customary has all the time been, We’ll understand it after we see it.

It’s lastly starting to happen to everybody, although, that customary was simpler to dwell with in 1926 than in 2026. That’s as a result of, in 2026, there’s this newfangled factor often called know-how. And should you’re planning to watch any minor-league baseball in Tacoma or Albuquerque this yr, you are about to grow to be very conscious of that.

For a few years now, baseball has experimented with utilizing bat-tracking know-how in the Low-A Florida State League to hone in on checked swings — and assist decide whether or not a batter swing at a pitch or not. That know-how is now coming to the Triple-A Pacific Coast League, beginning with every staff’s first full sequence in May.

It may have two intriguing new elements:

1. Hitters, catchers and pitchers can problem a checked-swing name — however it can rely in opposition to their two ABS ball/strike challenges if the authentic name is upheld. The thought there’s to introduce the new know-how however not overload every sport with extra challenges.

2. And for the first time, there will probably be wording that lays out what a “swing” is. According to the memo, if the “maximum angle between the bat head and the bat handle exceeds 45 degrees,” that will probably be thought-about a swing. Anything lower than 45 levels is taken into account a no-swing.

What’s the aim? It’s the newest chapter in baseball’s endless quest to scale back the strikeout fee. Will it work? We’ll discover out. But in the Florida State League final season, the strikeout fee dropped by greater than 3 proportion factors with this checked-swing know-how in place. So let’s examine if that interprets at greater ranges.

But there are two extra issues it is best to know. One is that 45 levels is usually thought to be considerably farther than many checked swings which might be at the moment being referred to as “a swing” (ie, a strike) in the massive leagues. So count on some fired-up pitchers and managers once they see how this goes.

Second, this know-how will solely be used in the PCL. It won’t be used in baseball’s different Triple-A league, the International League. However, the 45-degree customary will now be thought-about the dividing line between a swing and a checked swing. So International League umpires will probably be anticipated to implement the identical ideas, though groups will not have the know-how or a problem system to learn on in the event that they disagree. What might probably go improper there?

It will get tougher to beat the pitch clock

Three years after considered one of the most necessary rule adjustments in historical past, we all know this: The pitch clock works. Games are shorter. The motion is crisp. So why is MLB about to crack down on the authorized strategies gamers have designed to get that clock to cease once they want a breather?

It’s as a result of video games really bought two minutes longer in the massive leagues final yr, creeping from 2 hours, 36 minutes for the common nine-inning sport to 2:38. So the league desires to check out just a few anti-stalling measures simply to see what works.

No batter timeouts in Low A — In Low-A leagues, batters will not be allowed to name timeout at any level in an at-batapart from “special circumstances.” The league’s definition of these circumstances: brushbacks, damage issues, “bona fide” gear points, and so on.

Limited batter timeouts in High A — In High-A leagues, batters can name time solely with a runner on base. Again, the identical “special circumstances” will probably be the exception.

Shorter timeouts in Double A and Triple A — At these higher ranges, batters can nonetheless name time. But umpires will not await the hitter to be prepared earlier than they restart the clock. Instead, they’ll instantly reset the pitch clock — and hitters have to be again in the field, eyes locked on the pitcher earlier than the clock hits eight seconds remaining.

Crackdowns on PitchCom glitches — The league has (appropriately) found out that pitchers are actually stopping the clock extra usually by routinely claiming their PitchCom units aren’t working. In Triple A, they will nonetheless try this, however it will likely be counted in opposition to their “mound visit” limits. If a pitcher claims his PitchCom is on the fritz after his staff is out of mound visits, it will likely be thought-about a pitch-clock violation — which means it is an automated ball.

Quicker mound visits — Speaking of mound visits, the league desires to pace these up. So all through the minor leagues, there will probably be a mound-visit countdown clock. And everybody besides the pitcher has to depart the mound earlier than that clock hits zero. If that does not occur, it can even be thought-about a pitch-clock violation.

Catchers will probably be on the clock — Across the minor leagues, catchers can not cease the clock by getting out of their crouch and leaving their place to give defensive alerts to the infielders. The clock now will proceed to tick, and the catcher wants to be again in the catcher’s field earlier than it hits 9. That, too, will probably be a pitch-clock violation if he would not make it.

What’s the aim? The league apparently considers these strategies to be a light type of chicanery. So it desires to gauge the influence of conserving these clock-stopping tips to a minimal. It’s attainable none of this may ever attain the massive leagues. But it isn’t inconceivable, both.

Starting pitchers returning to the sport

If you watch a whole lot of spring coaching baseball, you are already conversant in this. A beginning pitcher will get in bother in the second or third inning. His pitch rely for the inning ticks shut to 25 or 30. So the supervisor has the freedom to take him out of the sport for the remainder of that inning, then carry him again to begin the subsequent inning.

That rule is now coming to baseball’s three growth leagues: the Arizona Complex League, Florida Complex League and Dominican Summer League. It won’t be in impact in any of the extra superior leagues.

What’s the aim? This is one change that has no implications for another league. It’s purely a security valve to maintain the youngest pitching prospects in the sport from getting overloaded, fatigued and, probably, injured when an inning reels in the improper path. There are not any plans to broaden this one past spring coaching and these short-season leagues. So do not guess on the Pirates ever having the ability to strive it some evening with Paul Skenes.
