2026 MLB Home Run Derby: Format Changes & Betting Value

Before the big game, the heavy hitters take center stage. It is never too early to look at the MLB Home Run Derby format changes, as understanding the mechanics is crucial for finding an edge in the betting market. Here is how the new format works:

• No timer and no “outs.”
• Round 1: 20 swings.
• Round 2: 15 swings.
• Finals: 15 swings.
• Each swing counts toward a player’s allotment, whether it is a home run or not.
• If a player homers on their last swing in any round, they keep going until they fail to hit one out.
• There is no bonus round and no “bracket” for the first round.
• Tiebreakers: Home Run Distance for Round 1; three-swing swing-offs for Rounds 2 and 3.

Just as we saw in the past two events in 2024 and 2025, the participants with the top four home run totals from Round 1 will advance to the semifinals. From there, they will be seeded based on their first-round homer totals and face off head-to-head (No. 1 vs. No. 4, and No. 2 vs. No. 3) to determine the two finalists.

Home Run Derby Odds

Here are the current contestants for the MLB Home Run Derby Winner:

• Kyle Schwarber (Phillies)
• Junior Caminero (Rays)
• Munetaka Murakami (White Sox)
• Jac Caglianone (Royals)
• Jordan Walker (Cardinals)
• Bryce Harper (Phillies)
• Ben Rice (Yankees)
• Willson Contreras (Red Sox)

Analyzing these futures prices, Schwarber is understandably the betting favorite, especially in his home park. However, we’ve seen time and time again that the Derby format heavily favors repeatable swing mechanics over max-effort power, especially now that every single swing counts against a strict allotment. We are bypassing the top of the board to hunt for real value. Look at Ben Rice sitting at a 9/1 payout. Given the strict swing limits, a smooth, effortless swing path is highly correlated with stamina and consistency deep into the rounds.

How to Sign Up With the Underdog Promo Code BROAD

Getting started and claiming your $50 in bonus entries ahead of the American League versus National League matchup is a simple process. First, you will need to create and register a new Underdog account by providing your standard personal information. During this registration process, you are required to enter the promo code BROAD. Please note that you must be a new user and meet the specific legal age and region requirements for your jurisdiction to qualify.

Once your account is successfully registered, deposit at least $5 using one of Underdog’s secure payment methods. Finally, simply play a $5 entry to officially activate your $50 in bonus entries.

When configuring your entry, Underdog gives you two primary ways to approach the board:

• Standard Entry: By selecting 2+ picks, you can build a standard entry that will trigger the largest potential payout. However, keep in mind that all legs in a standard entry must hit for you to win.
• Flex Entry: The other option is to flex an entry featuring 3+ picks. While the maximum payout is slightly lower than a standard entry, a flex entry provides a built-in safety net, allowing you to still receive some winnings even if one of your selected legs is incorrect. It does stand to reason that smart bettors frequently utilize flex entries to hedge against variance.
