Myers' 19 home runs through Wednesday gave him the No. 6 seed and a first-round matchup against Cincinnati Reds outfielder Adam Duvall, who is seeded third. The seedings were based on the number of home runs the participants had hit as of Wednesday.
Myers will try to hit the pitches of his 19-year-old brother Beau, who recently completed his freshman season at Appalachian State, where he is an infield-outfielder. Myers was the National League Player of the Month in June when he hit 11 of his 19 home runs.
Myers and Duvall are both first-time Home Run Derby participants, as is Los Angeles Dodgers rookie shortstop Corey Seager.

The Duvall-Myers winner will face the winner of the first-round matchup between second-seeded Todd Frazier of the Chicago White Sox, the 2015 Home Run Derby champion, and seventh-seeded Carlos Gonzalez of the Colorado Rockies.
The top seed is Baltimore Orioles outfielder-designated hitter Mark Trumbo, who leads Major League Baseball with 28 home runs. Trumbo will face the eighth-seeded Seager, who has 17 home runs.
The Trumbo-Seager winner will face the winner of the matchup between fourth-seeded Robinson Cano of the Seattle Mariners, the 2011 Home Run Derby champion, and fifth-seeded Giancarlo Stanton of the Miami Marlins.
Each batter will get four minutes, with the clock starting with the release of the first pitch. Thirty seconds of bonus time will be awarded for two home runs that each equal or exceed 440 feet.
