Per MLB Network's Jon Morosi (h/t Danny Abriano of SNY.tv), the Rockies "want to engage with" the Mets about the five-time All-Star.
Arenado's long-term future with the Rockies has been cloudy for some time.
ESPN's Jeff Passan reported in January that the 29-year-old was unhappy with the team's inactivity in free agency after they finished 71-91 in 2019.
"There's a lot of disrespect from people there that I don't want to be a part of," Arenado told MLB.com's Thomas Harding in a text message. "You can quote that."
Arenado is entering the second season of an eight-year, $260 million extension he signed in February 2019. The deal includes an opt-out after the 2022 season.
The Mets could be a potentially hot destination for players this offseason. New team owner Steve Cohen has made it clear he wants to spend money on his roster and hopes to win a World Series within three to five years.
Per Ken Rosenthal of The Athletic and Fox Sports, James McCann is "closing in" on a four-year, $40 million deal with the Mets.
A potential Arenado deal would cost New York a lot more than that in terms of money and prospects. He's proved himself to be worth a significant cost as arguably the most complete third baseman in Major League Baseball. The California native has won eight straight Gold Glove awards and has a .293/.349/.541 slash line in 1,079 career games with the Rockies.
