Set the matchup
The batter card supplies both offensive and defensive results. The pitcher card brings an ERA-based modifier and an out limit into the at-bat.

One plate appearance
Match up. Roll. Read the play.
The complete engine stays on the two player cards, so the game keeps moving without losing the statistical character of the season.
Roll the dice
Add the two result dice for a total from 2–12. A separate die tells you whether to read the ODD or EVEN side of the batter card.
Apply the pitcher
Move the result by the pitcher modifier. The adjusted total always remains capped between 2 and 12.
Read the play
Use the adjusted row and the ODD or EVEN side. The cell gives the play: K, GB, FB, OUT, BB, 1B, 2B, 3B, or HR.

Where is the defense?
The defense is built into the batter card.
Legends of the Diamond does not require separate fielder-rating cards. Every batter card contains offensive results and defensive outs. The pitcher changes which row is used, and the final cell decides who wins the matchup.
Dice total2–12±Pitcher modifierUp or down→Batter cardODD or EVEN
K
The pitcher records a strikeout.
GB
A ground-ball out; follow the ground-ball rule for any runners.
FB
A fly-ball out; follow the fly-ball rule for any runners.
OUT
The defense records a routine out.
One matchup, one result. Hits, walks, and home runs favour the batter. K, GB, FB, and OUT favour the pitcher and defense.
The card system
Everything needed at the tabletop.
Batters carry the play results. Pitchers influence every matchup. Team cards keep the club information together.
01 · Batter card
The season becomes a result table
Each row contains two possible plays. Roll two dice for the 2–12 total, apply the pitcher modifier, then use the separate die to select ODD or EVEN.
- 1Position
OF identifies Ruth as an outfielder.
- 2SB success rating
SB 7 is a 1–12 rating based on stolen-base success. Higher is better.
- 3Batting average
Ruth hit .356 during the 1927 season.
- 4Adjusted roll
Find the final total from 2–12 after applying the pitcher modifier.
- 5ODD or EVEN
The separate die selects the side, and that cell gives the play result.
Example with Ed Rile
Roll 8, apply Rile’s NEG-4, and move to row 4. If the separate die is EVEN, Ruth’s result is 1B.
