in the two innings. 1991–2005 Beginning in 1991, the format changed to a 3-round contest. From 1991 to 2006, 8-10 players were selected and hit as many home runs as possible before reaching 10 outs in each round. The tally reset for each round, with the top four advancing to the second round, and the top two advancing to the final. In honor of the World Baseball Classic, the 2005 contest featured eight players from different countries. The format remained the same. 2006–2013 The format changed slightly in 2006. Instead of the tally resetting for each round, it was only reset before the final round. Therefore, the players with the four highest totals after Round 1 advanced to Round 2, and the players with the two highest sum of Round 1 and 2 advanced to the finals. 2014 The Home Run Derby format was changed significantly in 2014, as MLB sought to speed-up the contest and increase the drama. In the new bracket format, five players from each league faced the other players in their league in Round 1, with each players having seven "outs." The player in each league with the highest Round 1 total received a second-round bye, and the players with the second- and third-highest Round 1 totals from each league faced off. The Round 2 winner from each league faced the Round 1 winner, and the Round 3 winner crowned the league winner. The final featured the winner of each league. Each round stands alone, with the score reset for each round. Ties in any round are broken by a 3-swing swing-off. If the players remain tied, the players engage in a sudden-death swing-off until one player homers. 2015-2019, since 2021 The format was changed once again in 2015. The most significant change was the elimination of "outs", which was replaced by a time limit. Eight players are seeded based on their season home run totals and are given five minutes to hit as many home runs as possible. The winner of each head-to-head matchup advances, until a final winner is determined. If a tie occurs in any match-up, two sets of tiebreakers are employed: first, a 1-minute swing-off decides the winner; thereafter, multiple swingoffs of 3 swings until a winner is determined. Further, a player can get "bonus time" in the last minute of each round. During that time, the clock would stop for each
