A trade of Nolan Arenado from the Colorado Rockies to the St. Louis Cardinals has either been agreed to, or is close and is still being worked on, or is still being discussed but isn’t done yet, depending on the reports you believe.
Reports indicate that a deal, if it does happen, would have Arenado waiving his no trade clause to go to the St. Louis Cardinals, keeping his opt out for after the 2021 season, getting an opt out for after the 2022 season, deferring some cash, and keeping his no trade rights otherwise.
