Kansas City Royals manager Ned Yost may have been ejected from his team’s game against the Cincinnati Reds on Tuesday, but it wasn’t because he was wearing his Apple Watch.

After concerns were raised during the game about whether Yost wearing an Apple Watch in the dugout gave his team an unfair advantage over its less-connected adversaries, Major League Baseball told MarketWatch it is not banning smartwatches during games.

The MLB staffers managing on-field operations did call Yost to make sure he wasn’t using the data on his watch, which was, ironically, given to Yost by the MLB a month ago as a gift for his participation in the All-Star Game, an MLB spokesman said. But it was just a routine call.

And:

The MLB does have official rules in place that ban other Internet-connected mobile devices from the dugout, bullpen and field during ballgames. Uniformed personnel, clubhouse staff and equipment staff are prohibited from using cellphones, including any type of portable or mobile phone, laptop, texting device or “similar portable equipment” once batting practice has begun. The use of these devices is also prohibited in the clubhouse within 30 minutes of the start of the game.

I wonder what will happen when watchOS 2 is officially released and apps can run on the watch without a connected phone. I can’t imagine Major League Baseball will ban smart phones in the dugout and not extend that ban to the Apple Watch. Interesting.
