Stanton, who leads the National League in home runs (21) and RBI (62) and ranks in the top 10 for average (.308), was named an All-Star reserve for the second time. In 2012, he was unable to participate in both the Home Run Derby and Midsummer Classic because of arthroscopic knee surgery.
The 24-year-old entered the final week fourth among NL outfielders in voting. Since the game is being held at Target Field, home of the Minnesota Twins of the American League, the club may use him as the designated hitter.
Stanton is already scheduled to compete in the derby after being asked by captain and Colorado Rockies shortstop Troy Tulowitzki.
Just two Marlins have ever been voted in by the fans: third baseman Gary Sheffield (1993) and shortstop Hanley Ramirez (2008-10).
