In the early days of this year’s season, torpedo bats have become all the rage for big-league hitters. And now, they are showing up in almost every big-league clubhouse.

From Moneyball to analytics to torpedo bats, MLB teams are desperate for an edge and will look for one in every nook and cranny.

The newest innovation in baseball, the bat has a seemingly inflated barrel that is thickest and heaviest where the player most frequently makes contact.

There have been two companies that have filed with the U.S. Patent & Trademark Office. Importer Michael Hauptman's Just Happy LLC filed for three trademarks, desiring to put "Torpedo Bat" and or "Torpedo Barrel Bat" on bats and "Torpedo Bat" on clothing and apparel, including apparel, baseball gloves, bat bags and glove bags.

Long before his oddly shaped bat became the talk of baseball, Aaron Leanhardt played in the Boston Metro Baseball League. He wasn’t the only guy on the team to reach the big leagues.

By now, you’ve probably heard about baseball’s greatest innovation since the curveball: MLB’s new “torpedo” bat, the reconfigured bat that moves the barrel — or the sweet spot — closer to the handle, seemingly turning even the most meager of hitters into home run machines.

Torpedo bats are just the latest innovation in the design of baseball bats, some of which stuck, and others which ... did not.

"I think it’s an amazing discovery," said Angels outfielder Taylor Ward, one of many players suddenly interested in the new bats.

Torpedo bats drew attention over the weekend when the New York Yankees hit a team-record nine homers in one game.
