It looks like Major League Baseball may have to rethink its stance on Apple Watches.

The Red Sox have been using Apple's wearable as part of an elaborate cheating scheme to intercept their opponents' hand signals, according to The New York Times.

It's not clear exactly how all this went down but the report says Boston's MLB team has admitted to investigators that the team's trainers use their Apple Watches to pass information to players about the opposing team's hand signals during some games.

The scheme, which has been going on for "at least several weeks," came out after the New York Yankees had filed a complaint with the league over the Red Sox's tactics. The Yankees reportedly had video evidence showing Red Sox trainers looking at their watches and passing information to players, including outfielder Chris Young.

According to The Times:

In the clips, the team’s assistant athletic trainer, Jon Jochim, is seen looking at his Apple Watch and then passing information to outfielder Brock Holt and second baseman Dustin Pedroia, who was injured at the time but in uniform. In one instance, Pedroia is then seen passing the information to Young.

As the report points out, the league has a longstanding tradition of teams trying to figure out each other's hand signals, but the rules prohibit players from getting extra help from gadgets and other devices.

An MLB spokesperson didn't immediately respond to a request for comment.

This isn't the first time questions have been raised about Apple Watch use during baseball games. In 2015, soon after the Apple Watch had launched, many speculated whether Kansas City Royals Manager Ned Yost had been thrown out of a game for wearing one. The league later clarified it had not banned the devices from the dugout so long as they were not being used with a data connection.

But, in light of recent events, they may have to revisit that policy.
