The 2016 MLB Home Run Derby kicks off All-Star week on Monday night at Petco Park in San Diego. Eight contestants will participate in the competition, with two former champions looking to win the event for a second time.

MLB home-run leader Mark Trumbo is the No.1 seed in the eight-man tournament that features three rounds. The players are given four minutes to hit as many home runs as possible, and two home runs of at least 440 feet earn contestants an extra 30 seconds.

Todd Frazier is the No.2 seed after winning the derby a year ago. He is tied for second in the Majors with 25 home runs. Robinson Cano has 21 homers, and he's also a former winner.

The Chicago Cubs' Kris Bryant has 25 home runs, but he won’t compete in Monday’s contest. Five MLB players are tied for fourth with 23 home runs at the All-Star Break, and four of them—Edwin Encarnacion, Nelson Cruz, Josh Donaldson and Nolan Arenado—won’t be in the derby.

The No.8 seed, Corey Seager, has the fewest home runs of anyone in the competition with 17. Frazier had 25 home runs in the regular season when he won the title in 2015, but the previous four winners all had 15 homers or less at the All-Star Break.

The derby is scheduled to begin at 8 p.m. ET, but because of introductions, the contest won’t actually start until 10-15 minutes later.

Start Time: 8 p.m. ET
