The 4th Inning Program in MLB The Show 26 Diamond Dynasty continues the game’s structured XP reward grind, and its Boss Choice Pack is one of the main highlights of the entire inning cycle. This tier is where most players start planning their grind route, because the bosses are not just high-rated cards—they also shape how your squad performs in both ranked and offline modes.

For the 4th Inning, the Boss Pack features two standout diamonds: Roger Clemens and Rafael Devers. Both cards sit at 97 OVR and represent very different playstyles, giving players a real choice depending on roster needs rather than just picking the “best overall” card.

Roger Clemens is the pitching option in this inning. As a 97 OVR starter, he is built around velocity and pitch variety, making him a strong frontline arm for ranked play. Clemens typically plays like a power pitcher who can dominate long outings when used correctly. His value comes from swing-and-miss ability and the kind of pitch mix that punishes aggressive hitters. If your rotation already lacks a true ace or you want a reliable ranked starter, Clemens is usually the safer pick.

Rafael Devers is the offensive boss option. Also rated 97 OVR, he slots in as a third baseman with elite hitting attributes. Devers is designed for run production, with strong contact and power numbers that make him a middle-of-the-order threat in almost any lineup. Compared to Clemens, Devers is the more straightforward impact bat—he helps immediately in Conquest, Ranked Seasons, and event modes where scoring quickly matters.

The structure of the 4th Inning Program is built around XP progression rather than one single grind path. Players earn XP through a combination of gameplay missions, stat milestones, and PXP objectives tied to specific card series. Common requirements include accumulating PXP with Topps Now, Cornerstone, and Spotlight Series players, along with hitting and extra-base hit milestones across different game modes. This design encourages players to rotate squads rather than stick to one lineup.

Once players reach the Boss Pack tier and choose a card, progression doesn’t stop there. If both Clemens and Devers are collected, the game offers an additional Boss Collection reward that grants a large XP bonus toward the next inning program. This creates an incentive for completionists or heavy grinders to eventually pick up both cards instead of stopping at one.

Beyond the bosses, the 4th Inning content cycle also includes additional featured players and monthly reward cards, including high-profile Lightning and Retro Lightning items that expand the overall meta. While those aren’t part of the Boss Pack itself, they contribute to the same ecosystem of XP grinding and roster building that defines the inning system.

In short, the 4th Inning Program Bosses in MLB The Show 26 are designed around choice and team-building direction. Clemens strengthens pitching depth with a power arm profile, while Devers boosts offensive consistency with elite hitting production. The “best” pick depends entirely on whether your team needs dominance on the mound or extra firepower at the plate, which is exactly what makes this inning cycle feel meaningful rather than repetitive.
