It's been revealed that the Yankees are using new custom bats known as "torpedo" bats, which have more wood at the label to give a larger spot to the area where players make contact.

Some oddly-shaped baseball bats have become a hot topic among fans and players, after the Yankees’ so-called “Torpedo Bats” seemingly helped some sluggers hit multiple home runs.
