Per John Clark of NBC Sports Philadelphia, the Phillies have yet to make a formal offer to Realmuto's camp even though the two sides have had conversations.
This is at odds with a report from MLB Network's Jon Heyman on Monday that the Phillies have "an offer out" to Realmuto.
Philadelphia's front office was in a state of flux until recently. The organization had no general manager for two months after Matt Klentak resigned in October. Dave Dombrowski was hired on Dec. 11 as president of baseball operations.
Dombrowski hired Sam Fuld as general manager on Dec. 22.
Following the end of the 2020 regular season, Phillies managing partner John Middleton told reporters that re-signing Realmuto was his No. 1 priority
"The point I made is, we need J.T. now, but we really need J.T. in three, four, five, six years from now and if all we get for him is two years, that's not the same thing as two years of Cliff Lee in 2009," he said. "We were a little early in the development to make that kind of a play."
MLB.com's Todd Zolecki reported in November that Realmuto is seeking "a record-shattering contract for a catcher" that could approach $200 million.
Philadelphia acquired Realmuto from the Miami Marlins in February 2019. The 29-year-old made the All-Star team, won a Silver Slugger and Gold Glove award in his first season with the Phillies.
Realmuto posted a career-high .840 OPS with 11 homers and 32 RBI in 47 games during the 2020 season.
