If you're trying to unlock the 91 OVR Mexico City Series Zac Gallen card in MLB The Show 26, the easiest and most reliable method is by completing the Mexico City Series Conquest Map in Diamond Dynasty. For most players, this is the best route because it costs nothing and gives multiple rewards along the way.
A lot of players immediately check the marketplace when a special Diamond card drops, but Zac Gallen is actually very obtainable through gameplay if you're willing to spend a little time grinding offline content.
Why the 91 OVR Zac Gallen Card Matters
The Mexico City Series Zac Gallen card quickly became one of the more valuable program rewards because it isn't just a strong pitcher — it also helps progress larger collections.
Many players are targeting this card because it works as a voucher toward unlocking the 99 OVR Miguel Cabrera collection reward. That alone makes it worth picking up early, especially if you're planning to stay competitive in Diamond Dynasty throughout the season.
On top of that, the card itself performs extremely well.
Gallen's pitching mix plays nicely against both lefties and righties, and his control feels noticeably sharper than many other early Diamond starters. His off-speed pitches tunnel well, and his stamina makes him useful in longer Ranked games.
The Best Free Method: Complete the Mexico City Series Conquest Map
The smartest way to unlock Zac Gallen without spending stubs is to fully complete the Mexico City Series Conquest Map.
If you've played Conquest before, the process is pretty straightforward:
Capture territories across the board
Steal fans when needed
Defeat enemy strongholds
Finish every objective tied to the map
It takes some time, but it's much cheaper than buying the card outright from the marketplace.
The nice thing is that this map gives more than just Zac Gallen. Completing the full conquest also rewards players with a 91 OVR Ramón Laureano card, so you're getting multiple Diamond rewards from one grind.
For offline Diamond Dynasty players, this is honestly one of the better value programs currently available in MLB The Show 26.
Tips for Finishing the Conquest Faster
A few small strategies can speed up the grind significantly.
First, don't waste turns stealing fans unless the objective specifically requires it. Most Conquest maps can be completed faster by aggressively expanding territory and eliminating weaker CPU spaces early.
Second, simulate low-risk games whenever possible. Save your actual gameplay time for strongholds and critical matchups.
Third, bring pitchers you're actively leveling with Parallel XP. Since you'll already be grinding innings, you might as well make progress on other cards while working toward Zac Gallen.
A lot of players also stack Team Affinity missions during Conquest runs to maximize efficiency.
Alternative Method: Buy Him From the Marketplace
If you don't enjoy offline modes or simply want the card immediately, you can buy the 91 OVR Mexico City Series Zac Gallen directly from the Community Marketplace.
This is obviously the fastest option, but prices can fluctuate heavily depending on market demand and current collections.
Early on, special Diamond cards tied to major collections usually stay expensive because competitive players rush to complete vouchers quickly.
If you're low on stubs, grinding the Conquest map is probably the better move.
If you're sitting on a large bankroll from flipping cards or selling pack pulls, buying him outright can save several hours.
What About the Regular Live Series Zac Gallen?
There’s also the standard Live Series Zac Gallen card available for players who only need him for collections, exchanges, or Arizona Diamondbacks missions.
That version is much cheaper and easier to obtain.
The base Live Series card is only a 74 OVR Bronze and usually costs almost nothing on the marketplace. In many cases, you can buy it instantly for under 50 stubs.
You can also pull the Bronze version from standard packs, although pack odds are always inconsistent.
Some Team Affinity Bronze/Silver Arizona packs offer better chances if you're specifically hunting Diamondbacks players.
Is the Grind Worth It?
For most Diamond Dynasty players, yes.
The Mexico City Series Zac Gallen is one of those cards that stays useful longer than expected because of both his gameplay value and collection importance.
Even if he eventually leaves your ranked rotation, he still helps toward major set rewards later in the year.
And since the Conquest map also gives additional Diamond rewards, XP, packs, and hidden bonuses, the grind rarely feels wasted.
If you're trying to build your team efficiently without draining your stubs, completing the Mexico City Series Conquest Map is absolutely the best way to unlock Zac Gallen in MLB The Show 26.
