MLB Home Run Derby Preview, Probability
The structural rules are as follows:
- Round 1: 20 swings per player. There is no bracket for this opening round.
- Round 2: 15 swings per player.
- Finals: 15 swings per player.
- The “Last Swing” Rule: Every swing counts toward the allotment, but if a player hits a home run on their final swing in any round, they keep going until they fail to hit a home run. There are no additional bonus rounds.
- Advancement & Seeding: Just as in 2024 and 2025, the four participants with the highest home run totals in Round 1 advance to the semifinals. They are then seeded based on their first-round totals to face off head-to-head (No. 1 vs. No. 4, and No. 2 vs. No. 3) to determine the finalists.
- Tiebreakers: Any ties in Round 1 are broken by longest home run distance. Ties in Rounds 2 and 3 are decided by a three-swing swing-off.
The eight-man field stepping up to the plate in Philadelphia features a mix of seasoned sluggers and rising stars: Kyle Schwarber (Phillies), Junior Caminero (Rays), Munetaka Murakami (White Sox), Jac Caglianone (Royals), Jordan Walker (Cardinals), Bryce Harper (Phillies), Ben Rice (Yankees), and Willson Contreras (Red Sox). Take a look at the current probabilities to win the Home Run Derby:
- Kyle Schwarber: 22%
- Junior Caminero: 18%
- Munetaka Murakami: 16%
- Jac Caglianone: 13%
- Jordan Walker: 12%
- Ben Rice: 11%
- Bryce Harper: 10%
- Willson Contreras: 6%
