Stanton has a fracture in the hamate bone and will have surgery, reports Joe Frisaro of MLB.com. ESPN's Tim Kurkjian reported that Stanton will be out 4-6 weeks with the injury, which occurred while swinging a bat in the ninth inning yesterday.
The Marlins announced on Twitter that Stanton will go on the 15-day disabled list. The team will bring up outfielder Cole Gillespie from Triple-A New Orleans, they also announced.
Stanton's injury will be tough on both Marlins fans and baseball fans alike. He has been one of the best players in baseball this season, slashing .265/.346/.606 with baseball-leading marks of 27 homers and 67 runs batted in over 318 plate appearances.
Rosenthal noted that Stanton's injury could push the Marlins to sell at the Trade Deadline. They do have some interesting and movable pieces come July 31.
