Almost a week after Colorado's Troy Tulowitzki was chosen as captain of the National League team, Stanton agreed to participate in the slugfest. Fans should be in for a show, as the 24-year-old can easily be found powering balls into upper decks during batting practice. He's been able to translate that strength into games, too, where he's averaging a Majors-best 423.8 feet per home run, according to ESPN's Home Run Tracker.
Stanton's longest blast sailed 484 feet on April 4 against the Padres. That had been the longest homer hit in the Majors this season until Mike Trout crushed a 489-foot homer on June 27.
Even though Trout has surpassed the Marlins slugger this year, no one has hit a moonshot farther than Stanton since Aug. 12, 2012, when he drove a ball 494 feet in Colorado.
Stanton's road to the Home Run Derby has been a long one. He was nominated to the NL team in 2012, but he had to withdraw due to surgery on his right knee the day before the contest.
Stanton, who is tied with Tulowitzki for the most home runs in the NL with 21, will be the fourth player in Marlins history to participate in the Home Run Derby. Miguel Cabrera competed in 2006, followed by Dan Uggla in '08 and Hanley Ramirez in '10.
