Championship Series Event

Welcome to the Championship Series Event!

START: Friday, October 13 | 6 p.m. ET / 3 p.m. PT

DIFFICULTY: All-Star; Online head-to-head

Build lineups with the current MLB postseason teams in the Championship Series Event.


All Events are free to enter. 


Events have their own dedicated lineup, but you only can use player items from your Inventory.

Players from the Astros, Yankees, Cubs, and Dodgers are eligible to enter the Championship Series Event. The player items can be Live Series, Legends and Flashbacks. Your team overall is 99 OVR, so build your best teams possible!

Don’t forget, you can filter the Community Market on by each team.


The Championship Series Event consists of only 6-inning games.


The reward system is similar to Battle Royale in Diamond Dynasty where you collect rewards as you pass win milestones.

(A hidden hitting Mission has a Postseason Flashback reward in the Events Mission category. Try to swing for the fences during Championship Series Event games to reveal it!)


If you win 3, 6, 9 or 12 games before double elimination, you can earn one of these rewards in a single Event entry:

  • 3 WINS PER ENTRY: Silver Live Series Player
  • 6 WINS PER ENTRY: Gold Live Series Player
  • 9 WINS PER ENTRY: Low Diamond Live Series Player (90-93 OVR)
  • 12 WINS PER ENTRY: Postseason Legend Cal Ripken Jr. (Diamond, 93 OVR 3B)

Q: Do I have to win 12 games-in-a-row without losing to get these rewards?
A: No. Similar to Battle Royale, you can earn the 12-win reward even if you lose once during the entry. Your record would be 12-1. Your wins per entry only resets after losing twice.

Q: If I win 12 games in the same Event entry, do I collect all of the 3, 6, 9 and 12-win rewards?
A: Yes.


You can earn these rewards for piling up wins while the Event is open:

  • 5 WINS CUMULATIVE: 1 Gold Live Series Player Item
  • 10 WINS CUMULATIVE: 1 Ballin is a Habit Pack
  • 20 WINS CUMULATIVE: 1 Postseason Pack (Guaranteed Gold or Diamond Postseason player)
  • 25 WINS CUMULATIVE: Postseason Legend Warren Spahn (Diamond, 97 OVR SP)


Two losses eliminates your current lineup entry from the Event, but you can re-enter for free right away with any lineup that meets the Event requirements. The benefit of double elimination is the opportunity to rebuild your team if you want to swap out players.

Q: If I lose two games and my current lineup is eliminated from the Event, does it reset my Cumulative Wins?
A: No, the Cumulative Wins will continue to track until the end of the Event.


Look for four new Division Series Recap Missions under the Events category in Diamond Dynasty that challenge you to achieve what the current Postseason teams and players accomplished over the last week. Remember, you must play in Events games to earn progress towards these Missions:

  • Play with Yankees shortstop Didi Gregorius and match his heroic stats from Game 5 of the ALDS
  • Play with Houston Astros infielders and tally hits, runs, RBI and home runs to match their offensive output during the American League Division Series
  • Play with Dodgers and accumulate extra base hits, including doubles, triples and home runs
  • Protect the lead by using Chicago Cubs relievers to rack up holds and saves


The Postseason Pack returns to the Show Shop at half price! Originally, it cost 20,000 Stubs, and it will now be priced at 10,000 Stubs for the next week. The pack guarantees one Postseason Flashback or Legend (Diamond or Gold rarity). In the Postseason Pack, you can find these player items:
