This is the "price" for a Christian Yelich trade

Marlins won't move the 26-year-old unless they get back "star-level talent

Christian Yelich's name has been in the trade rumor mill for much of the offseason, and the buzz has picked up again after the center fielder's agent said Tuesday that Yelich hopes to be traded before Spring Training starts. According to MLB Network insider Peter Gammons, any deal would have to bring a "huge return" for Miami.

Citing conversations with teams that have called the Marlins about Yelich, Gammons said Wednesday on MLB Tonight that the Marlins won't move the 26-year-old unless they get back "star-level talent." As one example, Gammons said Miami has told the Braves that uber-prospect Ronald Acuna would have to be included in any trade for Yelich.

"The Marlins told the Braves, 'Look, we'll do a three- or four- or five-for-one, but Ronald Acuna has to be in it or we don't go even to the second player,."

Acuna is one of baseball's very top prospects. He currently ranks as MLB's No. 6 overall prospect, according to MLB Pipeline, and could move up even further on that list in the upcoming 2018 rankings. The 20-year-old outfielder seems likely to be promoted to the big league club early next season.

Gammons said Acuna is a player the Braves won't trade, and the fact that the Marlins would tell the Braves that he would have to be the minimum headliner of any Yelich deal indicates that they're "shooting very high."

Following Miami's trades of Giancarlo Stanton, Marcell Ozuna and Dee Gordon to the Yankees, Cardinals and Mariners, respectively, Yelich and catcher J.T. Realmuto have been floated as the next players the team could potentially move as part of its rebuilding effort.

Gammons also mentioned Realmuto in the segment, saying that other teams' general managers think the Marlins might wait to trade Realmuto closer to the 2018 Trade Deadline. | BUZZ
