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

The new bats caused excitement when New York Yankees hitters clobbered home runs with them opening weekend, and that has some Portland players eager to give the torpedo bat some swings.

Yahoo has taken a big step, announcing Friday that in its leagues, the MLB players who are using torpedo bats will be denoted with a special icon. Here's how it looks on their site, with the example lineup including Yankees catcher Austin Wells, Phillies third baseman Alec Bohm and Mets shortstop Francisco Lindor as the players with the icon.

ARLINGTON - Joc Pederson became the first Ranger to deploy a torpedo bat. Result: Initial failure to launch. Pederson, a self-described bat lover, got a few bats on Friday from the Sam Bat and Tucci companies, gave them a whirl in batting practice and took it into the game against Tampa Bay.

Of note is how D-backs pitchers handled the five Yankees who are known to be using the torpedo bat: Anthony Volpe and Paul Goldschmidt, who bat righty, and Jazz Chisholm Jr., Cody Bellinger and Austin Wells, who bat lefty.

After a number of hitters adopted the new bowling-pin-looking bats during MLB opening week, FanDuel and DraftKings Sportsbooks are offering special bets related to the movement. DraftKings has an entire section made up of players that have used a torpedo bat this season, including Elly de la Cruz, Francisco Lindor, Dansby Swanson, and others.

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.

Torpedo bats are thinner at the top with more wood closer to the batter’s hands. The Yankees debuted these new bats in their opening weekend and hit 15 home runs.
