Per SiriusXM's Craig Mish, the Marlins have asked the Astros for outfield prospect Kyle Tucker in discussions for Realmuto.
Jeff Berry, Realmuto's agent, told Barry Jackson of the Miami Herald that his client prefers to be traded by the Marlins before the start of spring training.
“No matter how his arbitration hearing turned out, J.T.’s preference remains the same,” Berry said. “He would like to be traded to another organization before spring training so he has an opportunity to compete for a championship.”
The Marlins have been among the most active MLB teams this offseason after trading Giancarlo Stanton, Dee Gordon, Christian Yelich and Marcell Ozuna.
Tucker ranked No. 17 on MLB.com's top 100 prospects for this season. The 21-year-old hit .274/.346/.528 in 120 games at High-A and Double-A in 2017.
Realmuto, who will make $2.9 million in 2018 after losing his arbitration case, set career highs with 17 home runs and a .451 slugging percentage last year.
