The premier event of MLB’s All-Star Weekend will look different in 2026. Philadelphia will host the Derby to celebrate the United States’ 250th birthday, and Netflix will carry the coverage, introducing some new faces to the live broadcast. But the Derby itself is also undergoing changes.
In June, MLB announced a return to a swing-based format for the Derby, though some elements from recent years will remain. Here’s what to know about the 2026 Home Run Derby rules.
Bracket and structure
The overall bracket format will stay the same as in previous years: eight hitters start in Round 1, and the four participants with the most home runs in that round advance to the semifinals. In the semifinals, those four players are seeded based on their Round 1 totals, and two head-to-head matchups determine the finalists. The two top hitters then compete for the championship. The bracket isn’t fully implemented until Round 2, by which time four players have already been eliminated.
Swing-based format
The key change for 2026 is a return to a swing-based competition. Instead of chasing the most home runs in a fixed time, hitters will be allotted a specific number of swings per round. Each swing taken—whether it results in a home run or not—will count toward the player’s allotted total. If a player hits a home run on their final swing, they’re allowed to keep swinging until they fail to hit a home run.
Tiebreakers and rounds
Round 1 tiebreakers will be decided by the distance of the furthest home run among tied players. When the competition reaches Rounds 2 and 3, ties will be resolved with a three-swing swing-off, giving each tied batter three additional attempts to swing for the fences.
Swing counts by round
– Round 1: 20 swings per batter
– Round 2: 15 swings per batter
– Round 3: 15 swings per batter
Important notes
– Each round’s swing count is a hard limit. Every swing, whether resulting in a home run or not, counts toward the total.
– The shift back to a swing-based format represents a return to a more traditional approach, while preserving certain structures from recent years, including the eight-to-four-to-two progression and the final head-to-head championship.
This summary captures the 2026 Home Run Derby’s new rules and how they change the way hitters approach the event, with a focus on the swing-based format, round-by-round swing limits, and how ties are resolved. For fans following the latest developments in the 2026 Derby, this format emphasizes strategy around swing management and depth of rounds while keeping the classic bracket progression intact.
