Meet with MIT Physicist ‘Torpedo’ used by Marks Coach Yankees behind the bats

The bats of the New York-New York York Yorkees were the story of the team’s franchise record against Milwaukee Brewers on Saturday. Then the debate came about the real bats used by some players in the 20-9 win.
The uniquely shaped timber is the result of a two -year research and experiment with an old Massachusetts Institute of Technology and Physicist Turned coach.
Question at the center?
“Where are you trying to hit the ball?” Aaron Leanhardt said in a phone call on Sunday morning. “Where are you trying to communicate?”
Leanhardt, 48 -year -old, started to work in 2022 when Yankees became a member of the Small League hit department, and brought them to the big leagues where the team was the chief analyst last season, and some players, including Shortstop Anthony Volpe, tried them in games. According to the outdoor player Cody Bellinger, now at least he will use it in games at the beginning of this season.
With the torpedo -like shape, the bats are specially produced for player preferences, and the most dense part of the bat is the place where a particular striker comes into contact with baseball most often.
“Really,” he said. “It’s about making the bat as heavy and fat as possible in the area you’re trying to damage in baseball.”

Major league baseball spokesman Athletic Bats do not break any rule. MLB Rule 3.02 indicates that a bat will be a smooth, round rod in the thickest piece of more than 2.61 inches and not more than 42 inches. The bat will be a single solid piece of wood. ” He also says that “experimental” bats cannot be used from “manufacturer Major League Baseball until they get the approval of design and production methods”.
When asked if technology is an inventor, Leanhardt said that this was a group of efforts and that the results were due to his interviews with coaches, players, MLB and bat manufacturers.
“The loan goes to those who buy him, Lean Leanhardt said. “But if people want to throw credit to different people, then I’ll take some cuts.”
However, a Yankees official said Leanhardt deserves the loan to be “too .. He accepted the retired Energy Kevin Smith de Leanhardt, who spent a portion of the four seasons in the major.
Yes, Yankees has a real genius MIT physicist Lenny (man) in the payroll. He invented the barrel of “torpedo”. It brings more wood and mass to your contact with the most common striker. The idea is to increase the number of “barrels ve and to reduce longing. pic.twitter.com/cSc1wkam9g

Leanhardt followed an unusual path for baseball.
He has a bachelor’s degree and doctoral degree at the University of Michigan. MIT Physics. Between 2007-2014, he is a professor of physics at the University of Michigan.
Leanhardt started coaching the Atlantic League in 2017 and coaching a Montana Community College before joining Yankees in 2018. In 2024, the club in the main branches, the first “Major League analyst”, “and” quantitative information is responsible for integrating the use of field performance and preparation, “he said.
Why should you leave the academy for baseball?
“I think one of the great things about this sport is very competitive,” he said. “The men are willing to force the envelope. This is just an opportunity to take my past to an area and find ways to innovate.”
Leanhardt said that the biggest concerns of talking to players over the years were two -way. They wanted to make more contact with the fields and they wanted to hit the ball more often with the bat “sweet point” or the most dense area.
“They will point to a place on the bat with a place under the tip of the bat or seven inches down,” he said. “The sweet point is typically here. Only with the conversations you think of yourself, we don’t change how much wood we put against how much wood we put it against? This original concept is the original concept. Just try to get all this weight and try to put it in a sweet point in return and try to put a sweet diameter and use a clue.
Leanhardt said he didn’t see much disadvantage to redistribute the weight of the bat.
“The bat speed should remain the same,” he said. “Perhaps the bat rate may increase a bit depending on how you want to redesign the bat. But in the end a more fat barrel, you get a heavier barrel at a sweet point. So in a sense, you can eat your cake and here. In fact, you can get some gains without sacrificing.”
Leanhardt said he didn’t want to talk about individual players’ experiences of the new bat. Yankees said that the striker Giancarlo Stanton gave to journalists at the beginning of this month, last season, in the list of both elbows, the ligament that caused the existing list of ligament tears, “probably some bat adjustments”, he said. Then he added: “I don’t know why.” Leanhardt refused to comment on Stanton’s situation.
“You should ask Yankees’ medical staff.” “I will postpone all these questions to Yankees’ medical men.”
Leanhardt said that the arrival of a new bat design in a radical way was the “nature of our business”.
“On that day, people shook very heavy bats made of Hickory, and someone had the idea of shaking something like Ash, and in the 1920s, the ’30s were a kind of revolutionary in this transition, and then the industry remained on the route for a while”. “Ultimately, it requires people to be willing to be forward -looking, asking people right questions.”
On Saturday, he shot a stroke of seeing the passion for social media caused by bats. Some players began to use them last season, “the whole industry caught the wind” and “Offseason exploded,” he said.
“That’s why you see it in the hands of many men right now,” he said. “Obviously, (Saturday) performance was very careful.”
It received a lot of coordination for the production of bats from the design stage. Leanhardt said that he would “guarantee” with the authorities who control the bat arrangement in MLB and önteen Everyone who runs the lathe for every bat manufacturer in baseball ”.
“You really communicate with every company, and you really try to find the person who knows the wood and knows how to turn the wood on a lathe. You just establish a relationship with these men and you convince the players to be as successful as possible. They want the players to be as successful as possible. “It really accumulated.”
