CNN — Baseball season is back, and it didn't take long for the New York Yankees to start crushing records and dominating conversation. And at the center of it all? "Torpedo" bats.
The Bronx Bombers tied an as they hit 15 home runs in their opening three-game series 鈥� including a nine in their 20-9 rout over the Milwaukee Brewers on Saturday.
Here's all you need to know about the "torpedo" bats that have everyone talking.
What is the 'torpedo' bat?
The " 鈥� so named due to its shape resembling a torpedo 鈥� is a customized bat that tailors the barrel for each hitter. Gone is the standard swell of the bat as it's replaced with more wood in the barrel shifted closer to the hands.
It's all about locating a hitter's so-called "sweet spot" and moving more wood to that area 鈥� and because every hitter's sweet spot is different, so too is their "torpedo" bat.
The Yankees analytics department looked at every player's hitting data so that the widest part of the bat 鈥� or the barrel 鈥� could be placed where they most often hit the ball.
For shortstop Anthony Volpe that meant moving the barrel closer to the label on his bat, according to YES Network Michael Kay. Volpe's Jazz Chisholm Jr., Cody Bellinger, Paul Goldschmidt and Austin Wells were also swinging torpedo bats this weekend.

Who invented it?
The torpedo bat was developed by MIT physicist Aaron "Lenny" Leanhardt when he was an analyst in the Yankees organization.
Leanhardt said the idea was as he noticed a common concern voiced from batters who wanted to make more, and better, contact with pitches.
"It's just about making the bat as heavy and as fat as possible in the area where you're trying to do damage on the baseball," Leanhardt told .
"It's just through those conversations where you think to yourself, 'Why don't we exchange how much wood we're putting on the tip versus how much we're putting in the sweet spot?'
"That's the original concept right there. Just try to take all that excess weight and try to put it where you're trying to hit the ball and then, in exchange, try to take the thinner diameter that used to be at the sweet spot and put that on the tip."
Leanhardt has since moved to the , taking up a role as a field coordinator.
Why doesn't every team use it?
Although the Yankees' performances are driving the "torpedo" bat narrative, they are not the only team dabbling in its use.
