All Strat-O-Matic Baseball 365 leagues use this Standard Injury System, with the exception of 2015 season leagues who have explicitly chosen to play with the new Super-Advanced Injury System.
Hitter injuries
A hitter has a chance to be injured whenever he is at the plate, and the dice roll comes up with the specific roll on his card that contains "+ injury" (most hitter cards have one such roll, but some particularly durable ones do not). When this roll occurs, the length of the injury is determined by rolling a 20-sided die against the chart below. Note that players who had a relatively large amount of playing time during their corresponding real-life season have an upper limit on the length of a given injury (see "Injury duration limits" below).
| d20 | Result |
|---|---|
| 1-2 | Stays in game |
| 3-4 | Inj. for remainder of game |
| 5-8 | Inj. for 1 extra game |
| 9-11 | Inj. for 2 extra games |
| 12-13 | Inj. for 3 extra games |
| 14 | Inj. for 4 extra games |
| 15 | Inj. for 5 extra games |
| 16 | Inj. for 6 extra games |
| 17 | Inj. for 7 extra games |
| 18 | Inj. for 8 extra games |
| 19 | Inj. for 10 extra games |
| 20 | Inj. for 15 extra games |
Pitcher injuries
A pitcher can be injured in either of two ways:
- In a game where the DH is being used, if the pitcher in question is on the mound, and the opposing team's DH is at bat, if the dice roll is 6-12, the pitcher rolls on the Injury Chart above to determine his injury.
- In a game where the DH is not being used, the pitcher may be injured if he rolls the injury roll on the pitcher's batting card when he is at the plate. In this case, he rolls on the Injury Chart above to determine his injury.
Note that pitchers who had a relatively large amount of playing time during their corresponding real-life season have an upper limit on the length of a given injury (see "Injury duration limits" below).
Injury duration limits
Position players
| Real-life AB+BB | Max. length of injury |
|---|---|
| 0-599 | no limit (can be injured for the max 15 extra games) |
| 600-679 | 3 extra games |
| 680+ | remainder of game |
* NOTE: For the 2020 season Actual set only, in which players had a maximum of 60 real-life game appearances only, the 3 extra games limit starts at 223 real-life AB+BB instead of 600, and the remainder of game limit starts at 252 real-life AB+BB instead of 680.
Pitchers
| Real-life IP | Max. length of injury |
|---|---|
| 0-199 | no limit (can be injured for the max 15 extra games) |
| 200-299 | 3 extra games |
| 300+ | remainder of game |
* NOTE: For the 2020 season Actual set only, in which players had a maximum of 60 real-life game appearances only, the 3 extra games limit starts at 75 real-life IP instead of 200, and the remainder of game limit starts at 112 real-life IP instead of 112.
Explanation of "Inj" number in player lists
The number in the "Inj" column on player lists indicates each position player's susceptibility to injury - specifically, the location of the injury chance roll on his card. It ranges from 0 (cannot be injured) to 6 (most susceptible).
Additionally, if the number is bold and green, the player cannot be injured for more than the remainder of a game (he had 680+ AB+BB in real life); if the number is italicized and green, the player cannot be injured for more than 3 additional games (he had 600-679 AB+BB in real life) (see "Injury duration limits" above).
0 - no injury chance
1 - injury chance on roll of 2 or 12
2 - injury chance on roll of 3 or 11
3 - injury chance on roll of 4 or 10
4 - injury chance on roll of 5 or 9
5 - injury chance on roll of 6 or 8
6 - injury chance on roll of 7
