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.

The New York Yankees' use of the torpedo bat has caused some controversy but they're not the first team to utilise the new shape.

The torpedo bat won't be going away anytime soon based on MLB commissioner Rob Manfred's latest comments on the craze. Baseball's specialized bats which took over the league at the start of the season are perfectly legal per the rulebook but have still stirred up controversy over their unorthodox bowling-pin bat structure.
