The simulation uses the following player stats to determine at-bat outcomes, fielding plays, baserunning, and pitcher fatigue:

• PA: Plate Appearances
• H: Hits
• HR: Home Runs
• BB: Walks
• SO: Strikeouts
• SF: Sacrifice Flies
• HBP: Hit By Pitch
• singles: Singles
• doubles: Doubles
• triples: Triples
• kRate: Strikeout Rate (K/PA)
• bbRate: Walk Rate (BB/PA)
• hrRate: Home Run Rate (HR/PA)
• BABIP: Batting Average on Balls in Play

• TBF: Total Batters Faced
• IP: Innings Pitched
• H: Hits Allowed
• HR: Home Runs Allowed
• BB: Walks Allowed
• SO: Strikeouts
• HBP: Hit By Pitch
• kRate: Strikeout Rate (K/TBF)
• bbRate: Walk Rate (BB/TBF)
• hrRate: Home Run Rate (HR/TBF)
• BABIP: Batting Average on Balls in Play Allowed

• position: Defensive Position
• G: Games Played
• Inn: Innings Played
• PO: Putouts
• A: Assists
• E: Errors
• DP: Double Plays Turned
• FP: Fielding Percentage
• RF: Range Factor
• TZ: Total Zone Runs

• sbAllowed: Stolen Bases Allowed
• cs: Caught Stealing
• csPct: Caught Stealing Percentage
• pickoffs: Pickoffs
• armStrength: Arm Strength
• PB: Passed Balls

• runsBaserunning: Baserunning Value
• speed: Speed Rating

• battersFaced: Batters faced by current pitcher (used for fatigue effects)

These stats are used in combination to determine:

• At-bat outcome probabilities (K, BB, HR, 1B, 2B, 3B, Out)
• Double/triple play chances (fielding stats)
• Error rates (fielding stats)
• Steal and pickoff success (baserunning, catcher, pitcher stats)
• Passed ball/wild pitch rates (catcher stats)
• Baserunner advancement (speed, baserunning value)
• Pitcher fatigue effects (batters faced)
