JUPITER, Fla. — Brandon Nimmo is cleared to resume baseball activities, after precautionary cardiac tests conducted over two days indicated he isn’t at risk.

Mets general manager Brodie Van Wagenen declined to provide details Thursday about what prompted the testing on the outfielder, which followed the checkups players receive before the start of camp, but a source said Nimmo has an irregular heartbeat — a condition he’s known about for “years.”

As part of his recent evaluation, according to the source, Nimmo wore a heart monitor for a 24-hour stretch beginning Wednesday and underwent a stress test.

“We always want to be precautious and never want to put players in harm’s way,” Van Wagenen said before the Mets played the Marlins on Thursday night. “I think this was a perfect example of that.”

Nimmo had been scratched from Wednesday’s lineup shortly before first pitch so he could undergo the testing.

On Thursday, Nimmo’s wife, Chelsea Jane, tweeted there was no reason for concern about her husband’s health.

“I’m just gonna say it. Brandon is fine (other than wishing he could just do his thing & play!),” she tweeted. “The timing was inconvenient & has caused a media storm. He’s healthy and feels great, just have to be sure of these things. Hopefully we can get this all cleared up and move forward!”
