How to figure...
Batting Average: Divide the number of safe hits by the total number of at-bats (at-bats do not include walks, sacrifices, hit-by-pitch or times awarded first on obstruction or interference). Example: Cody Ross has 87 hits in 293 at-bats for a .297 batting average (87 divided by 293 equals .297).
Slugging Percentage: Divide the total bases of all safe hits by the total number of at-bats.
On-base Percentage: Add the total number of hits, walks and hit-by-pitch and divide by the total of at-bats, walks, hit-by-pitches and sacrifice flies.
Fielding Average: Divide the total putouts and assists by the total of putouts, assists and errors (total chances).
Earned Run Average: Multiply the total number of earned runs by 9, then divide by the number of innings pitched. Example: Calvin Chipperfield 106.2, 23 has 23 earned runs and has pitched 106.2 innings. His ERA is 1.94 (23 times 9 equals 207, divided by 106.66 equals 1.94 ERA).
Win-Loss Percentage: Divide the number of games won by the total number of games played. Example: Adam Bernero was 8-4 in 1999. His win-loss percentage is 66 percent (eight plus four is 12; eight wins divided by 12 games played is .666 or 66 percent).
Consecutive Hitting Streaks: A consecutive hitting streak shall not be terminated if the plate appearance results in a base-on-balls, hit batsman, defensive interference or a sacrifice bunt. A sacrifice fly shall terminate the streak.
Magic Number: Compute the number of games remaining, add one, then subtract the number of games ahead in the loss column of the standings of the closest opponent. Example: The Whitecaps are 41-29 and the Dragons are 37-33, and both teams have eight games remaining. The magic number is five (eight games remaining plus one minus four games ahead in the loss column equals five).
