U4GM: MLB The Show 26 Boss Pack Breakdown Grinding the current MLB The Show 26 live cycle feels less like a straight hallway and more like a set of switches you can flip in your own order. The 4th Inning Program lets you chase XP through missions, ranked hits, card-series PXP, collections, packs, and boss progress, while MLB The Show 26 stubs still matter when you're trying to patch gaps in your squad. What Is the 4th Inning Program Right Now The 4th Inning Program went live on June 5, 2026, and runs until July 9, 2026. That's longer than the first three inning programs, so it doesn't feel like you have to rush everything in one weekend. The main track goes to 400,000 XP. Once you clear that, a reward wheel triggers every extra 30,000 XP you earn. 1. The Main XP Path Is Built Around Clear Checkpoints If you like visible targets, this path is easy to read. You always know whether you're chasing a pack, Stubs, a mini-boss, or the boss choice pack. The key checkpoints are simple. • 57,500 XP gives you 95 OVR All-Star Mike Piazza. • 220,000 XP gives you 96 OVR All-Star Steve Carlton. • 340,000 XP gives you an 85+ Live Series Pack. • 400,000 XP gives you the 4th Inning Boss Choice Pack. • The boss pack is a 1-of-2 choice between Rafael Devers and Roger Clemens. That last part matters. You don't get both bosses from the main reward pack, so pick based on your roster need, not just card hype. 2. Packs And Stubs Add Real Value Along The Way This branch is for players who care about the side rewards as much as the boss. The path throws enough packs at you to make daily progress feel less empty. Notable reward totals include. • Eleven standard MLB The Show 26 pack entries appear across the listed path. • Five Ballin' is a Habit Packs are included before 400,000 XP. • Two Cityscapes Deluxe Packs and one Mural Deluxe Pack are on the track. • Headliners rewards appear as a generic Headliners Pack, Headliners Pack 8, and Headliners Pack 10. • The listed Stub rewards add up to 8,750 Stubs. Don't miscount the basic packs or the Stubs. The path is better than a quick glance makes it look, especially if you're also flipping or completing collections. 3. Launch Missions Give You A Fast First Push If you're starting late, the launch XP missions are the cleanest way to move early. They don't finish the whole path, but they get you near the first card reward fast. The first mission group includes. • 500 PXP with Topps Now Series players for 3,750 XP. • 500 PXP with Cornerstone Series players for 5,250 XP. • 2,000 PXP with Spotlight Series players for 7,500 XP. • 50 hits in Weekend Classic and/or Solo or Co-op Ranked for 7,500 XP. • 25 doubles in any mode on any difficulty for 7,500 XP. Those five missions total 31,500 XP. Add the 30,000 XP voucher for collecting 95 OVR Francisco Lindor and 95 OVR Juan Soto, and you're past Piazza at 61,500 XP. 4. Weekend Classic Helps, But Don't Guess The Rules Weekend Classic is active in the MLB The Show 26 cycle, but the available official info doesn't give the exact start hour, end time, rewards, or lineup rules. What you can safely use it for is limited. • An official April 7, 2026 post said Weekend Classic was back that Friday. • The 4th Inning Program links it to the 50-hit XP mission. • Solo Ranked and Co-op Ranked can also count for that same 50-hit mission. • There isn't sourced info confirming Weekend Classic eligibility for Topps Now, Cornerstone, or Spotlight PXP stacking. So, use Weekend Classic if you like competitive games. Just don't build your whole XP plan around unknown rules. Which 4th Inning Route Should You Choose Pick missions if you want fast early XP, ranked hits if you already enjoy online games, the Lindor and Soto voucher if you own both cards, and the full path if Devers or Clemens fixes your lineup.
