MLB The Show 26 Diamond Dynasty Features Revamped Parallel XP, Red Rarity

World Baseball Classic Shows Up in Mini Seasons, Programs

The 2026 World Baseball Classic is poised to be the primary draw for Diamond Dynasty in March in MLB The Show 26, and its integration into DD is impressive. Per Sony San Diego's Thursday Feature Premiere live stream focusing on Diamond Dynasty, the full 500-player roster of participants in the WBC from its 20 participating countries will appear in game, and more than a quarter of those players will be playable, with "over 133" WBC cards being touted as obtainable for DD users. And this seems to be happening largely or maybe exclusively in Mini Seasons, a mode that has been tweaked slightly to accommodate the WBC format.

Each WBC Mini Seasons experience substitutes one team in for one of the 20 countries playing in the 2026 WBC, whether that's the United States, Japan, the Dominican Republic, or whatever team seems like it might have the easiest road to the championship. Players will get to play through the four games of round robin pool play, then — if they qualify for them — the quarterfinals, semifinals, and final.

While that's a cool way of getting players' Diamond Dynasty squads a fantasy WBC experience, though, it should probably be noted it is not only not the actual WBC experience — players seemingly cannot just take the reins of one of the 20 teams and play through the 2026 WBC with those rosters! — but actively prevents that from ever being an experience in MLB The Show 26 unless the Mini Seasons mode is broken out of Diamond Dynasty and the replace-an-existing-team caveat removed. Viewed in this light, it's a massive missed opportunity.

If it's any consolation, integrating the WBC into Mini Seasons has also forced a significant quality of life update for Mini Seasons: Players can now tweak of the lengths for both individual games and Mini Seasons, mostly being able to choose between three- and nine-inning games and seven- and 28-game campaigns in the mode, potentially making for either swifter paths to rewards or longer and more realistic — and, for XP or mission grinding, riper for accumulation of stats — single-player experiences. ("Mostly" is applied as a caveat here because developers did suggest that the lengths of seasons or games could be locked in specific curated Mini Seasons.)

SDS also showed four WBC cards that will be available in Diamond Dynasty:

• 85 OVR Kyle Teel
• 88 OVR Travis Bazzanna
• 88 OVR Kazuma Okamoto
• 90 OVR Munetaka Murakami, who was specifically mentioned previously as earnable on an XP reward path, and who has 90+ Power against lefties and righties

Expect to learn more about WBC live content — multiple in-game programs have been confirmed — next week, as live content reveals and streams occur.

"Parallel XP 2.0" Promises Mods, Customizability

Parallel XP still requires accumulating experience points from in-game feats with players, anything from plate appearances to stolen bases to quality starts and holds. But getting them is getting a little easier — so long as players are willing to challenge themselves.

The multipliers of Parallel XP have changed a bit, with "big boosts" to multipliers for difficulty: All-Star is now an 80 percent bonus over Rookie, for example. Online play still has its own boosts, with a 50 percent bonus over offline play. This is clearly intended to address the optimal grind for Parallel XP in previous versions of Diamond Dynasty being clobbering Rookie-level AI opponents in Play vs. CPU games.

PXP has also been tuned to help make leveling up hitters slightly easier, as they have long lagged behind pitchers who can tally PXP with every strikeout and inning pitched.

But the most exciting thing about the Parallel XP system is clearly what SDS has termed "parallel mods" that allow players to tailor their players' improved attributes for Parallel levels to players' preferred builds. These are not fully customizable — players are doing something more like equipping their preferred boosts than individually adding points to each attribute — but the mods have tiers (Silver, Gold, and Diamond) that unlock as players reach Parallel levels (from I through V) with each card, with a staggering 57 mods in total being available as players fully level up the players. These mods also aren't automatically unlocked, with stat missions helping gate them, and can be swapped at any time, meaning that players will still have to earn those precious points in Power or Speed by swatting homers or swiping bags but do have the tools to make those feats somewhat easier.

Hitters and pitchers will get their own sets of hitting and pitching mods: Hitters appear to have Contact, Power, Fielding, and Speed mods, while pitchers have H/9, K/9, and Control categories. And while two-way players like Shohei Ohtani will have the entire swath of mods available to them, they can only have hitting or pitching mods activated at any one time, so they will only be boosted at the plate or on the mound in any given game, a seemingly necessary concept for balance. (And in additional notes on balance: Mods cannot be swapped out during a specific game, just before launching into one, and the concept of buffing or nerfing mods for balance purposes as the year progresses was explicitly mentioned during Thursday's Feature Premiere, so that idea will certainly float around in the community in months to come.)

This mods system is also both optional — players can simply take the +1s to every attribute that Parallel levels have granted since the mechanic was introduced, if they want the simplicity or well-rounded players that have been part of the pre-existing system — and integrated into the game in a variety of ways, like individual player card screens, to make things easier for players to access. (Players will also be able to sort cards by Parallel level in some fashion, making things slightly easier for grinders to manage.)

And there's a little bonus for the Parallel grinders, as the cards will display the usernames of the first players to achieve each Parallel level on their in-game cards.

Red Diamond Rarity Coming for 95-99 OVR Cards

One of the touted features for Diamond Dynasty — the Red Diamond rarity — appears to be largely cosmetic, as Red Diamond rarity is simply a treatment for players at 95-99 OVR. That this was revealed with a 99 OVR Signature Series Albert Pujols, which does appear gloriously crimson-colored in game, does not

And to be clear, this is simply instituting a new tier of "rarity" for the highest-OVR cards in game: Diamond rarity still exists for 85-94 OVR cards, with Red Diamond simply being the treatment for 95-99 OVR cards. Whether 90-94 OVR cards that reach 95-99 OVR status through Parallel tiering get the corresponding Red Diamond treatment was not addressed on stream.

Other Notable Details

• Pitching out of the stretch as the only option for online play, originally touted as a gameplay change for MLB The Show 26, has been reverted. Players will still be able to toggle it as an option for offline play, but the adjustment players had vocally spoken out about having to make for online competitive play will no longer be necessary.
• And in another bone tossed to vocal community members: PCI shrinkage on pitches down and away, considered a bane of MLB The Show 25 and a contribution to a slider-heavy metagame, is being removed for online play for all difficulties.
• The drip-drip-drip reveal of the full roster of retired legends licensed for MLB The Show 26 continues. Previously revealed this week as new or returning Legends for Diamond Dynasty: Keith Foulke, Zach Britton, and Ron Santo. Confirmed as a new Legend for the first time since his retirement after an Easter egg-style appearance on an in-game scoreboard in Wednesday's Fielding Feedback trailer? Troy Tulowitzki.
• Appearing on a roster for the Long Ball Beasts team available in Play Now modes in a trailer — and thus licensed — were Chipper Jones, Mark McGwire, Ivan Rodriguez, David Ortiz, Larry Walker, Derek Jeter, and Sammy Sosa. (One of these things is kind of not like the others, as Jeter needed 20 seasons to get to 260 career homers and never hit 25 in any of them, but I digress.)
• Four Cleveland Guardians cards located within Team Affinity were revealed: An 83 OVR Shane Bieber, a Gold Carlos Santana from the , and 91 OVR Corey Kluber and Jim Thome cards from the Jolt Series whose rating might be +3 OVR based on the card having reached Parallel Level III. This was also confirmed as the structure for Team Affinity at launch: All 30 teams will have four Team Affinity cards available immediately in DD, with one Hitting and one Pitching Captain from the Jolt Series being the big prizes from the program to start.
• As has been previously mentioned, the BB/9 stat that has existed for pitchers for many years in MLB The Show has been folded into Control. As has perhaps not been said out loud by SDS before, Control is the "main driver for the PAR (Perfect Area Region) for pitching."
