MLB The Show 26 Best New Diamond Cards Ranked

The latest MLB The Show 26 roster update added five new Live Series Diamond cards: Fernando Tatis Jr., Ceddanne Rafaela, Dillon Dingler, Drew Rasmussen, and Matt Olson.

Not every Diamond card automatically becomes a must-use player. In Diamond Dynasty, a card’s real value depends on more than just overall rating. Position availability, defensive ability, hitting tools, lineup flexibility, and how well the player fits the current meta all matter. Players looking to build stronger lineups and improve their squads often focus on smart resource management, including how they spend their MLB The Show 26 Stubs.

After comparing these five new additions, Fernando Tatis Jr. and Ceddanne Rafaela stand out as the most useful cards from the update. Both bring something valuable that is difficult to replace, while the other three cards are more situational.

Here is the ranking:

Fernando Tatis Jr.
Ceddanne Rafaela
Dillon Dingler
Drew Rasmussen
Matt Olson

1. Fernando Tatis Jr. The Best All-Around Option

Fernando Tatis Jr. is the type of card that almost every Diamond Dynasty player can find a spot for.

His biggest strength is balance. He brings power at the plate, speed on the bases, and enough defensive ability to stay reliable in the outfield. Unlike players who only help in one area, Tatis Jr. can impact the game in multiple ways.

Power is still extremely valuable, especially when a hitter can also create extra-base opportunities with speed. His athletic ability gives him an advantage over many one-dimensional power bats.

For Ranked players, Tatis Jr. is the safer choice because he does not have a major weakness. He can fit into competitive lineups immediately and also works well for themed teams.

Best Use: Starting outfielder, DH option, competitive lineups

Strengths:

Great power and speed combination
Reliable defensive option
Fits almost every lineup style

Weakness:

Outfield has plenty of strong competition

2. Ceddanne Rafaela The Defensive Difference Maker

Ceddanne Rafaela shares the top spot because his versatility is something that cannot be easily replaced.

His ability to play center field, second base, and shortstop gives players more freedom when building their teams. Instead of locking into one position, Rafaela can solve multiple lineup problems.

Defense is often overlooked, but it can decide close games. A player with elite range and fielding can save runs that another card would give up.

The biggest question is his offense. Compared with pure power hitters, Rafaela may not produce the same home run numbers. However, his defensive value and flexibility make him useful even when his bat is inconsistent.

Best Use: Center field, utility role, defense-focused teams

Strengths:

Elite defensive value
Multiple premium positions
Great speed and athleticism

Weakness:

Offensive ceiling is lower than top power hitters

For players who like fast, defensive teams, Rafaela may actually be the better choice.

3. Dillon Dingler A Valuable Catcher Upgrade

Dillon Dingler ranks third because catcher remains one of the hardest positions to improve.

A strong catcher provides value beyond hitting. Throwing ability, defense, and controlling the running game all matter, especially in competitive matches.

Dingler’s biggest advantage is that reliable catchers are harder to find compared with other positions. Even if his bat does not stand out among elite hitters, his defensive tools make him useful.

Players who already have a top catcher may not need to make the switch, but for anyone looking for an upgrade behind the plate, Dingler is worth considering.

Best Use: Starting catcher, defensive lineups

4. Drew Rasmussen A Solid But Not Elite Starter

Drew Rasmussen adds another Diamond starting pitcher option, but pitchers face much tougher competition in Diamond Dynasty.

A starting pitcher needs something special to become a must-use card. Whether it is dominant pitches, elite attributes, or a unique playstyle, the best starters usually separate themselves quickly.

Rasmussen can provide rotation depth and help players who need another reliable starter, but he does not immediately stand above the top pitching options.

Best Use: Rotation filler, theme teams, budget rosters

5. Matt Olson More Useful for Collections

Matt Olson is the lowest-ranked card from this update, mostly because first base is already full of strong offensive options.

There is nothing wrong with Olson’s hitting ability, but his position limits his overall value. Many players already have powerful first basemen, making it harder for him to become a must-start option.

His biggest value comes from Live Series Collection progress. Players chasing collection rewards will still want him, but his gameplay impact is not as high as the other new Diamonds.

Best Use: Collection completion, backup lineup option
