Although his name has been floated around in trade rumors for the past year, 23-year-old slugger Giancarlo Stanton is "not available" on the trade market, Miami Marlins general manager Dan Jennings told ESPN's Jim Bowden on Saturday.
Jennings reiterated the Stanton will be the Marlins' starting right fielder on Opening Day 2014, adding that the organization is "building around him."
Speculation about Miami dealing Stanton -- who has 117 home runs, a .265 average and a .889 OPS in his first four seasons -- has swirled since the Marlins' fire sale last offseason with their salary dump trade of Jose Reyes, Josh Johnson and Mark Buehrle.
The Rangers, Pirates and Phillies are among the many teams that have been linked to Stanton.
Jennings also said that Miami is seeking upgrades at third base and catcher, and has discussed the possibility of trading for Red Sox third baseman Will Middlebrooks and Angels outfielder Mark Trumbo.
