Twins catcher Ryan Jeffers is using a Torpedo bat today : r/baseball

Imagine you're demolishing the interior of a house, and you have a choice for your next move. You could use a hammer—great for nails and small tasks—or you could grab a sledgehammer, built for breaking down walls with force and efficiency. The choice is clear.

Now, imagine if you could swing that sledgehammer with the speed and ease of a regular hammer—delivering the same crushing power but without the usual strain. It’s like stepping into a boxing ring with the knockout force of a heavyweight but the agility of a featherweight. You’re no longer choosing between power and speed—you have both, and that changes everything.

That’s the advantage the Yankees had over the weekend (among others). They were the first to popularize the ‘Torpedo Bat,’ and for good reason. Over the past few days, numerous articles have explored what this means for the game and what the trend says about hitters. As covered in this publication earlier, the bat’s redistributed weight gave players like Anthony Volpe more control over the handle—where he’s historically made much of his contact.

But the story of the ‘Torpedo Bat’ runs deeper. It all comes down to moment of inertia—a key factor in how heavy a bat feels to a hitter. I won’t go too far down the rabbit hole, but the main point is this: moment of inertia determines how easily a player can control and accelerate the bat through the zone. Typically, heavier bats allow hitters to transfer more force into the baseball, all else being equal. But that extra mass usually comes at the cost of control and swing speed, which is why the league’s biggest sluggers—like Giancarlo Stanton and Aaron Judge—are usually the ones wielding the heaviest bats.

Yesterday’s post covered how shifting mass toward the handle helps hitters make better use of the bat’s material. But the bigger breakthrough is this: by concentrating more weight near the hands, the Torpedo Bat actually feels lighter to the hitter. That means players can add mass to the bat—gaining more power—without sacrificing control or swing speed.

In other words, the Yankees may have found a way to let hitters swing a sledgehammer like it’s a regular hammer—and that could change everything.

This innovation forces us to rethink how hitters select their bats. Traditionally, players have focused on two key factors: bat weight and bat length. For decades, the rule of thumb has been simple—bigger players can handle heavier bats, while smaller players opt for lighter ones to maintain control. But what if that entire approach is outdated?

That’s where feel comes into play. In baseball circles, this is often referred to as swing weight—a more accurate way to assess how a bat actually plays in a hitter’s hands. Swing weight is influenced by how mass is distributed along the bat. Take a bat with a large barrel, for example—because more of its weight is concentrated at the end, the bat feels as heavy as its listed weight, say, 32 ounces.

But what happens if you shift that mass closer to the hands? Sound familiar? That’s exactly what we’re seeing with the Torpedo Bats. By adjusting the barrel placement, the effective swing weight decreases, making the bat feel lighter—even if its actual weight is heavier.

In essence, the Yankees and others have figured out how to add a few extra ounces to the bat while maintaining the same feel as a lighter model. And that’s why Jazz Chisholm, in his post-series press conference, made it a point to say:

“It doesn’t feel like a different bat”

"It gives you a feeling like you have more to work with”

For years, hitters have felt like they were playing catch-up. Pitchers have had the upper hand—benefiting from advances in pitch design, biomechanics, and technology that have reshaped the way they attack hitters. But this? This feels like a counterpunch. A way for hitters to finally tilt the balance back in their favor.

And it’s not going away. The Yankees’ weekend display made that clear, and teams across the league are scrambling to keep up. This isn’t just another bat—it’s a fundamental shift in how players think about their weapons at the plate. We’re watching the moment hitters stop playing defense and start dictating terms again. A small change with massive implications. Years from now, we might look back at this as the tipping point—the moment baseball’s offensive transformation truly began.
