Defending champion Todd Frazier and current home run leader Mark Trumbo headline the participants in the 2016 Home Run Derby. The field was announced on Thursday's SportsCenter.

The derby, which will take place Monday at San Diego's Petco Park, will follow the bracket format that began at last year's event. Matchups were seeded based on home run totals through Wednesday's games.

Trumbo, the Orioles' right fielder, leads the majors with 26 home runs and will be the derby's No. 1 seed. He will take on No. 8 seed Corey Seager, who has 17 homers with the Los Angeles Dodgers in his rookie season.

Frazier, the White Sox's third baseman, is the No. 2 seed this year and is second in the American League with 23 home runs. He will take on No. 7 seed Carlos Gonzalez, who has 18 homers this season with the Colorado Rockies.
