CSFBL tracks and displays a wide array of data and statistics. Here's a handy glossary of definitions and formulas

Batting Statistics (Standard)

G: Games
AB: At-bats
R: Runs scored
H: Hits
2B: Doubles
3B: Triples
HR: Home runs
RBI: Runs batted in
BB: Base on balls (includes intentional walks)
SO: Strikeouts
SB: Stolen bases
CS: Caught stealing
OPS: On Base Plus Slugging, calculated as: (OBP+SLG)
AVG: Batting average, calculated as: ( H / AB )        
OBP: On-base percentage, calculated as: ( H + BB + HBP / Plate Appearances )
SLG: Slugging percentage, calculated as: ( Total Bases / AB )

Batting Statistics (Extended)

PA: Plate appearances
TB: Total bases on hits, calculated as: ( 1B + 2 * 2B + 3 * 3B + 4 * HR)
GO: Ground ball outs
FO: Fly ball outs
FFO: Foul fly ball outs
SF: Sacrifice flies
HBP: Hit by pitch
GDP: Grounded into double play
ROE: Reach base on error (as a batter, not as a baserunner)
XB: Extra base taken on a fly out (tagging up) or a hit (as a baserunner)
BRO: Baserunning out - thrown out attempting to take an extra base on a fly
out (tagging up) or a hit (as a baserunner)
SA: Secondary Average
BABiP: Batting Average on balls in play, calculated as: (H-HR / AB-K-HR+SF)
xRC: Expected runs Created
LWTS: Linear Weights : ( 0.46 * 1B ) + ( 0.80 * 2B ) + ( 1.02 * 3B ) + ( 1.40 * HR ) + ( 0.33 * ( BB + HBP ) ) + ( 0.30 * SB ) - ( 0.60 * CS ) - ( LgABH * ( AB - H )

LgABH = League Average "negative value" of an out, typically about 0.25, this is calculated for each league/season, and is done so that it is easier to compare LWTS for players across different seasons.
xRAA: Expected Runs Above Average
ABHR: At bats per home run, calculated as ( AB / HR )
TBPA: Total bases per plate appearance, calculated as ( TB/PA )

Pitching Statistics (Standard)

G: Games

QA: Quality starts (defined as 6+ innings pitched and 3 or less earned runs)
CG: Complete games (pitcher started and finished the game)
ShO: Shutouts (complete game and no runs surrendered)
ERA: Earned run average, the number of earned runs every nine innings, calculated as ( ER / IP ) * 9
WHIP: Walks and hits per inning pitched, calculated as ( ( BB + H ) / IP )

Pitching Statistics (Extended)

SO9: Strikeouts per 9 innings, calculated as ( SO / IP ) * 9

G: Games
PO: Putouts
A: Assists
E: Errors
TC: Total chances, calculated as ( PO + A + E )
DP: Double plays
TP: Triple plays
