The five-time All-Star issued a statement Wednesday about the circumstances.
"There has been a lot of stuff going on that nobody knows about and I was reacting to what was said and was out of character for me because I’m very private with my life," Arenado wrote in a statement acquired by Patrick Saunders of the Denver Post. "The Rockies have been talking to my agent and me this offseason about a number of things that will remain between us.
"I will not speak on these things anymore. I'm getting ready for the upcoming season. I’m working hard to get better for my teammates and fans. NA28."
The seven-time Gold Glove winner wasn't happy Monday after Rockies general manager Jeff Bridich said the club is no longer looking to trade him.
Arenado's discontent also reportedly stemmed from Colorado's lack of action during the offseason to improve a team that won only 71 games last season.
The Rockies haven't responded to Arenado’s comments from Monday, according to Thomas Harding of MLB.com.
The 28-year-old agreed to an eight-year, $260-million extension last winter. The pact includes a full no-trade clause and an opt-out following the 2021 season.
