With 15 home runs in their first three games, the New York Yankees are flexing their muscles. Could part of their success be due to a new bat design?

Torpedo bats are the explosive new trend in baseball after the New York Yankees set a franchise record Saturday, hitting nine home runs — the first four of which were back to back to back to back — for a 20-9 victory over the Milwaukee Brewers.

The New York Yankees' new torpedo bats, developed by MIT physicist Aaron Leanhardt who has also done work for NASA, have gone viral and sparked a fierce debate.

Many of the Yankees used torpedo bats while posting historic numbers this weekend. Here's how the team started using the oddly-shaped bats and why they're legal.

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

MIT physicist Aaron Leanhardt has been credited with creating the torpedo bats. Leanhardt previously served as a hitting analyst with the Yankees before he joined the Miami Marlins as a field coordinator in the offseason.

The Yankees hit four home runs in the first inning off Brewers starter Nestor Cortes on Saturday, starting with three consecutive homers on three pitches. Their nine home runs broke the franchise record of eight and was one short of the MLB record, 10 homers in a single game accomplished by the Toronto Blue Jays in 1987.

The bats shaped like bowling pins at the end have baseball buzzing after they were used by Yankees players who contributed to a barrage of 15 home runs in the first three games.

After allowing 15 home runs in three games, the Brewers didn't make excuses: "It's not like some magical wood or anything else."
