Roster Update #24 was released for MLB The Show 26 on September 18, 2026, and it was mainly a maintenance-style update rather than another major attribute shake-up. There were 25 rating adjustments, with nine upgrades and no downgrades. For Diamond Dynasty players watching MLB The Show Stubs, the most important result was that no Live Series player crossed into the Diamond tier.

That leaves the market in an interesting position. Instead of reacting to a wave of new Diamond cards, players holding MLB The Show Stubs can concentrate on the Gold cards that may still have room to move. The next major roster update is expected around October 9, so there is still time to monitor performances and decide which cards deserve attention.

The Biggest Changes Were Not Diamond Promotions

Erick Fedde received one of the larger overall increases in the update, moving from 66 to 70 OVR. He also returned to starting pitcher as his primary position, making the card more consistent with his current role.

Daniel Lynch IV moved from 71 to 73 OVR and also received a primary-position adjustment to SP. These are useful changes for keeping Live Series rosters accurate, but neither one created a major Diamond Dynasty market event.

Justin Wrobleski was perhaps more notable for his attribute change. His overall remained at 76, while his Control rating increased significantly. For players who actually use the card, that can be more meaningful than the overall number suggests.

Watch the Players Near a Tier Change

Tanner Houck is one of the names that stands out when looking ahead. His Gold card has the potential to become more interesting if his pitching performance remains strong and the relevant attributes receive another boost.

For investors, the important thing is not simply whether Houck wins games or records strikeouts. You need to consider which attributes affect his overall rating and whether those attributes still have room to rise.

That is why a player's current card should always be compared with previous roster updates. Looking only at the overall number can hide changes that have already happened or make a potential upgrade appear more likely than it really is.

Crow-Armstrong Deserves Continued Attention

Pete Crow-Armstrong presents a different type of opportunity. He has already benefited from a substantial rating increase, which means his current price may already reflect part of the community's expectations.

His defense remains one of his strongest features, while additional offensive production could keep him in the conversation for future adjustments. The question is whether he can maintain that production long enough to justify another change.

This is also where patience matters. A player does not need to receive an upgrade in the next update to remain a useful long-term watchlist card. Sometimes the better approach is simply to wait and see whether the player's performance continues.

Keep Mason Miller on the List

Mason Miller is another card that deserves attention before the next major roster pass. His strong velocity and strikeout ability make him particularly interesting among relief pitchers.

Bullpen cards can sometimes move quickly when a key attribute changes. A relatively small adjustment to K/9 or another important pitching category can have a noticeable effect on the overall rating.

At the same time, Miller should not be treated as a guaranteed Diamond promotion. Update #24 produced no such movement, and future changes will depend on how SDS evaluates his performance and attributes.

Exchange Cards Still Have a Role

Not every market opportunity needs to involve an expensive Gold or Diamond card. Silver cards sitting close to their quick-sell value can still be useful for exchange strategies when the numbers work.

The safest way to approach this method is to calculate the purchase cost before placing a large number of orders. If the market price rises too far above quick-sell value, the potential return may no longer justify the investment.

This strategy can also help players who want to stay active in the market without putting all their resources into one roster-update prediction. The market may be quieter than it was during earlier parts of the year, but smaller opportunities can still appear when supply and demand change.

Looking Toward October

The biggest takeaway from Roster Update #24 is that the absence of Diamond promotions does not mean there is nothing to monitor. It simply shifts the focus toward players who could benefit from another round of attribute changes.

Houck, Crow-Armstrong, and Miller all have different cases, so comparing their recent performances and card attributes is more useful than treating every Gold player the same. The period before the next major update gives Diamond Dynasty players time to gather information rather than make rushed decisions.

For players looking for additional market flexibility before the next update, keeping resources available can be useful because prices often move once the community begins preparing for roster changes. Players comparing MLB 26 Stubs for sale should therefore consider their total Diamond Dynasty budget and upcoming needs rather than spending everything on a single investment idea.
