The playoff hopes of the surprising Marlins have taken a huge and potentially fatal blow. On Sunday afternoon, Miami manager Don Mattingly announced that Stanton, who was placed on the disabled list earlier that day with a groin strain, will miss the rest of the season. According to general manager Michael Hill, Stanton suffered a Grade 3 groin strain that will keep him off the field for at least six weeks, and likely longer. The injury robs the Marlins of their best power hitter and leaves a hole in the lineup that will be immensely difficult to fill as the team chases a postseason spot.
