Outfielder Christian Yelich is "unhappy'' over the Miami Marlins' player exodus this offseason, sources told ESPN, but he wants to give the team's front office a chance to explain its rebuilding plan before he assesses his future with the franchise. Yelich, who spoke earlier this offseason with Michael Hill, the Marlins' president of baseball operations, expects to have a follow-up conversation with Hill this week because he's trying to be "respectful'' of the organization, said a source familiar with the situation. Now that the Marlins' new Derek Jeter-led ownership group has signed off on trading Giancarlo Stanton, Dee Gordon and Marcell Ozuna in the quest to cut payroll, attention has focused on Yelich and catcher J.T. Realmuto, budding stars who are likely to attract considerable interest if they were made available in trades. Realmuto's representatives at CAA spoke with the Marlins recently and expressed the catcher's desire to play elsewhere in 2018, said a source. Realmuto has only three years of service time, so he's not in a position to demand a trade -- only to convey his unhappiness and ask the club to accommodate his wishes to be dealt. Realmuto hit 15 homers and ranked eighth among MLB catchers with a .765 OPS this season while earning a base salary of $562,500. That combination of production and affordability could make him a popular trade target. Yelich, similarly, has no leverage to demand a trade. He has four years left on a multi-year contract that will pay him a guaranteed $44.5 million through 2021.
