Major League Baseball announces 2 new rule changes for the 2025 season

Major League Baseball is back at it again, tweaking the game with two new rule changes for 2025 that feel equal parts logical and, well, open to debate.

According to Evan Drellich of The Athletic, Major League Baseball’s competition committee unanimously approved these changes on Tuesday.

Closing the Loophole on Shift Violations

Remember when MLB banned the infield shift in 2023, requiring two infielders on each side of second base? Teams got clever, toeing the line by parking a fielder dangerously close to the second-base bag. Major League Baseball has now responded with a stuff new penalty.

Starting in 2025, if a fielder violates the shift rule and is the first to touch the ball on that play, the batter automatically gets first base. Any runners on base will get to move up a bag too. To add insult to injury, the violating fielder gets slapped with an error.

The shift ban was meant to inject more offense into the game by opening up the field for hitters. Teams skirting the rules undermined that goal, and now, Manfred and company are drawing a harder line.

“Abandonment” on Replay Reviews

The second change is a bit more nuanced but could have big implications. Replay officials will now get a broader scope when reviewing plays at second or third base.

Previously, if a runner beat the throw but overran the bag, they were still safe if replay confirmed they got there first. Not anymore.

Starting next season, replay officials can determine if a runner “abandoned” the bag after beating the throw. If they did, the runner can be called out, even if they were initially safe.

Essentially, it forces players to maintain control and awareness after reaching the base—a subtle but potentially significant adjustment that tightens up baserunning strategy.

Rule Changes: A Rob Manfred-Era Trademark

These changes are par for the course in the Rob Manfred era, which has been defined by a constant pursuit of modernization or, depending on who you ask, overregulation.

From the pitch clock to the ghost runner, Manfred hasn’t been afraid to shake things up in the name of pace and excitement.

For better or worse, these two new tweaks for 2025 aren’t as polarizing as previous changes.

The shift penalty seems like a direct response to teams gaming the system, while the replay adjustment adds a layer of accountability to baserunning. Both feel like an attempt to tidy up areas where rules left a little too much wiggle room.

Will These Changes Matter?

The shift penalty might have the bigger immediate impact.

Teams that relied on those borderline positioning strategies will now have to recalibrate, and hitters could see a bump in offensive production.

The replay tweak, meanwhile, feels more situational—like the kind of rule you won’t notice until it decides a pivotal moment in a big game.

Still, these changes continue to show MLB’s willingness to evolve, even if the moves are small. The bigger question, as always, is whether fans will embrace them or keep longing for a purer version of the game.

Either way, the 2025 Major League Baseball season is already shaping up to be another interesting chapter in baseball’s never-ending dance between tradition and innovation.
