Principles
- The scoresheet is the source. It is copied as written, and every number is calculated from it automatically.
- Players are identified by team + jersey number. Names on sheets vary (nicknames, English, short forms), so the number decides when a name is unclear.
- Only registered players (the league roster) count in stats. At-bats of players not on the roster, or who left, stay on the scoresheet but not in individual stats. A player who changed teams mid-season keeps his stats from both teams.
- Forfeits: the score and scoresheet stay as played and the game is marked “forfeit”. The result counts as a forfeit, and individual stats from that game do not count.
- Forfeit, not played: shown as ”- : -” with “forfeit”. There is no scoresheet, so no individual stats.
- The math is the same as the league has always used (the chairman’s Excel).
League style (how it differs from regular baseball)
- No errors are recorded. Reaching on an error counts as a hit.
- Sacrifices (bunt or fly) are written as FC and count as outs. They count as at-bats.
- Walks and hit-by-pitch are combined into W.
- A dropped third strike (NO) counts as a strikeout, even when the batter reaches.
- No stealing. Runners may go on a bounced pitch, so runs often outnumber hits.
- No ERA, runs or RBIs. Pitchers are judged by BOP.
Batting
| Stat | Meaning | Formula |
|---|---|---|
| H | Hits | 1B + 2B + 3B + HR |
| O | Outs | outs + FC + double plays |
| K | Strikeouts | strikeouts + dropped third strikes |
| AB | At-bats | H + K + O |
| W | Walks + HBP | |
| TPA | Plate appearances | AB + W |
| AVG | Batting average | H ÷ AB |
| OBP | On-base percentage | (H + W) ÷ TPA |
| SLG | Slugging | (1B + 2×2B + 3×3B + 4×HR) ÷ AB |
| G | Games | games with at least one plate appearance |
Example: 5 PA, 4 AB, 2 hits (one double), 1 walk → AVG 0.500, OBP 0.600, SLG 0.750
Qualifying PA = team games × 2.5. AVG/OBP/SLG rankings include qualified batters only.
Pitching
Counted from the opposing plate appearances that pitcher faced.
| Stat | Meaning | Formula |
|---|---|---|
| 4 / 3 / 2 / 1 | HR / triples / doubles / singles allowed | |
| K | Strikeouts | |
| O | Outs recorded | outs + FC + double plays |
| BB | Walks + HBP | |
| BAT | Batters faced | hits + K + O + BB |
| BOP | Batter-out percentage | (K + O) ÷ BAT |
| INN | Innings appeared in | facing even one batter counts that inning as 1 |
| G | Games pitched |
Example: 20 batters faced, 5 strikeouts, 9 outs → BOP = 14 ÷ 20 = 0.700. Higher is better.
Qualifying = team games × 10 batters faced. BOP rankings include qualified pitchers only.
Win · Loss · Save
- The W/L/S written on the scoresheet is used as is.
- Win (Section 21): a starter must complete 3 innings to get the win; otherwise it goes to a reliever.
- Save (Section 27): the winning team’s last reliever who holds the lead and meets one of:
- entered with a lead of 5 runs or fewer and faced at least 3 batters
- entered when the runners on base, the batter and the next batter would tie or take the lead if they all scored
- faced at least 6 batters
- Loss: per KBO rules, the pitcher who gave up the go-ahead run that held.
Standings
- PCT = (W + 0.5 × T) ÷ G. A tie counts as half a win.
- Standings are by league (club).
Leaderboards
- Home runs, hits, walks+HBP, AVG, OBP, SLG, wins, saves, strikeouts, BOP, Iron Arm (batters faced).
- Top 10 for each; ties share the same rank. Within a tie, batters are listed by higher AVG and pitchers by higher BOP.
Career totals · clubs (all-time records)
- Career totals cover hits and strikeouts (pitchers). Retired players are included.
- Through the 2026 season the numbers are the chairman’s records (CLUB sheet); from 2027 the scoresheet totals are added.
- Clubs: the date a player passed 100 · 333 · 444 · 555 · 700 career hits or strikeouts, hitting for the cycle (single, double, triple and home run in one game), and shutouts (one pitcher throws the whole game and allows no runs; time-limit and mercy-rule games count).
- From 2027 these are found automatically from the scoresheets. Shutouts are posted after a person checks them. New milestones show on the home page for one week.
