selected currently consists of four American League players and four National League players. The first Derby in 1985 featured five from each league, and the 1986 and 1987 events featured three and two players from each league, respectively. In 1996, the field was again expanded to ten players, with five from each league (though in 1997, the AL had six contestants to the NL's four). In 2000, the field reverted to the current four-player-per-league format. The only exception was 2005, when Major League Baseball changed the selection criteria so that eight players represented their home countries instead of their respective leagues. The change was believed to be in promotion of the inaugural World Baseball Classic, played in March 2006. In 2006, the selection of four players from each league resumed. In 2011, the format was revised so that team captains selected the individual sides. For the first time in Derby history, Shohei Ohtani became both the first pitcher and the first Japanese player to participate in 2021. Some notable performances in the Derby include Bobby Abreu in 2005, who won the Derby with a then-record 41 homers, including a then-record 24 in the first round. Vladimir Guerrero Jr. broke the first-round record in 2019 with 29 home runs. He broke that record in the following round, hitting 40 home runs in 2 tiebreakers. The previous overall record was set in 2016 by Giancarlo Stanton, who finished with a total of 61 home runs, defeating Todd Frazier in the final round. The current overall record is held by Guerrero Jr. at a mark of 91, set in 2019. Only three participants, Yoenis Céspedes, Stanton, and Pete Alonso, have won the Home Run Derby without being selected to the All-Star Game. Alonso broke Guerrero's first-round record in 2021 with 35 homers on his way to his second straight Derby Title (the first being in 2019 with a final round win over Guerrero). Overview Format 8 players duel in a home run challenge. 1985–1990 In the early years of the Home Run Derby, 4-10 players from both the AL and NL were selected to participate. Each player was given 2 "innings" to hit as many home runs as possible before reaching 5 outs. For the derby, an out is defined as any swing that is not a home run. The winner of the contest was the player with the most total home runs
