LOS ANGELES – Diamondbacks coach Ariel Prieto admitted he made a mistake wearing his Apple Watch in the dugout during Wednesday night’s wild-card game, but he said he was not using it for any illicit purpose.

“My watch has been in airplane mode for about two days,” Prieto said. “If they want to take my Apple Watch, take my phone, they can do it. I wasn’t doing anything. I know it’s a rule, I know I missed that, but if they want to investigate, they can have it.”

Major League Baseball is investigating the situation, according to a report by the New York Post.

This comes only weeks after the Boston Red Sox were fined for using a watch in the dugout to relay signs to hitters.

Prieto, an extra coach on the Diamondbacks staff who also serves as an interpreter, said he has apologized to manager Torey Lovullo for forgetting to leave the watch in the clubhouse.

“It’s a rule and you have to follow the rule,” Prieto said. “But it’s been on airplane mode for the last two days. I have no chance of texting anybody or anything.”

Prieto was spotted on the TBS broadcast in the dugout with the watch on his wrist.

The Post reported that Major League Baseball has seen screenshots of the broadcast and has launched an investigation.
