It's all about the numbers |
| Calculating Statistics Many people like to calculate player statistics. I'm not one of them, but I decided to add a page about it anyway. I will use the following symbols in calculating the statistics: (+) addition, (-) subtraction, (*) multiplication, and (/) division. |

Offensive Statistics |
| Base-on-balls Percentage (total walks) / (plate appearances) |
| Batting Average (total hits) / (official at-bats) At-bats do not include walks, sacrifice flies, sacrifice bunts, obstruction calls, catcher's interference, or being hit by a pitch. If a player makes it safely on base due to an error, it is an at-bat, but not a hit. |
| Home Run Ratio (at-bats) / (home runs) |
| On-base Percentage (hits + walks + hits by pitch) / (at-bats + walks + hits by pitch + sacrifice flies) |
| Slugging Average (total bases) / (at-bats) The number of total bases only includes those obtained from hits; not from errors, walks, or interference calls. |
| Stolen Base Percentage (stolen bases) / (total attempts) |
| Strikeout Ratio (at-bats) / (strikeouts) |
| Defensive Statistics |
| Fielding Average (total putouts + assists) / (putouts + assists + errors) |
| Pitching Statistics |
| Earned Run Average (earned runs * 9) / (innings pitched) |
| Opponents' Batting Average (hits allowed) / (at bats allowed) |
| Winning Percentage (games won) / (games won + games lost) |
| Team Statistics |
| Won-Lost Percentage (wins) / (wins + losses) |
| Other Statistics (The "unofficial" statistics) |
| Fielder's Range Factor (putouts + assists) / (games) |
| Runs Created [(hits + walks - caught stealing) * (total bases + (stolen bases * 0.55)] / (at-bats + walks) |
