Where to Find Polo Grounds in MLB The Show 26

[MiraDaneLara]

The Polo Grounds is one of MLB The Show 26’s most iconic and unique stadiums. If you’re looking to add it to your Diamond Dynasty collection, it’s not as simple as buying it or completing a card set anymore. In 2026, the Polo Grounds is unlocked through a stat-based mission in the My Legacy program.

How to Unlock Polo Grounds

Mission Requirement: Hit 30 triples in any eligible game mode.

Where to Track Progress:
Go to Diamond Dynasty → Programs → Assorted Programs → My Legacy, then scroll down to the “Triples” section. Here, you can see how many triples you’ve recorded and how many more you need to hit.

Eligible Game Modes:
Progress toward the 30 triples counts in nearly all full simulation-style modes, including:

Diamond Dynasty (online or offline)
Road to the Show
Franchise Mode
Strategies to Earn 30 Triples Quickly

Triples are notoriously tricky to get, so here are some tried-and-true methods to speed up the grind:

Speed-Focused Lineup: Use players with 90+ speed and strong contact/gap power. Avoid pure sluggers—they might hit home runs instead of triples.
Play in Big Ballparks: Choose stadiums with huge outfield gaps like Forbes Field, Coors Field, or Comerica Park. These give the ball more room to roll and let you stretch doubles into triples.
Offline Grinding: Play against the CPU in Mini Seasons or Conquest at lower difficulties. The AI is less aggressive, making it easier to hit balls into the gaps and reach third base safely.

Once you hit the 30th triple, the Polo Grounds card will automatically appear in your stadium inventory, ready to use in Diamond Dynasty games.
