New York sent infielder Luisangel Acuña and minor league pitcher Truman Pauley to Chicago for Robert, who has struggled with injuries and inconsistency since a stellar 2023 season.
A three-time All-Star and two-time Gold Glove winner, J.T. Realmuto made his decision a month after designated hitter Kyle Schwarber also chose to remain with the Phillies.
The infielder can opt out after the first and second season. He would receive $47 million for one year and $89 million for two years, according to the report.
