Here’s a comprehensive guide to the most important baseball statistics and what they mean.
Batting Statistics
- Batting Average (AVG)
- Formula: Hits / At-Bats
- Description: Measures a player’s hitting success. An average above .300 is considered excellent.
- On-Base Percentage (OBP)
- Formula: (Hits + Walks + Hit by Pitch) / (At-Bats + Walks + Hit by Pitch + Sacrifice Flies)
- Description: Reflects how often a player reaches base. An OBP above .400 is outstanding.
- Slugging Percentage (SLG)
- Formula: Total Bases / At-Bats
- Description: Indicates a player’s power by measuring the number of bases earned per at-bat. A SLG above .500 is considered powerful.
- On-Base Plus Slugging (OPS)
- Formula: OBP + SLG
- Description: Combines on-base ability and power into one metric. An OPS above .900 is elite.
- Runs Batted In (RBI)
- Description: The number of runs a player drives in. High RBI totals indicate a player’s effectiveness in clutch situations.
- Home Runs (HR)
- Description: The total number of home runs hit. This is a key indicator of a player’s power-hitting ability.
- Runs (R)
- Description: The number of times a player scores. This depends on the player’s ability to get on base and the hitting of subsequent batters.
- Hits (H)

- Description: The number of times a player is struck out. While strikeouts are often negative, power hitters may have high strikeout totals.
- Stolen Bases (SB)
- Description: The number of bases a player steals. This indicates speed and base-running acumen.
Pitching Statistics
- Earned Run Average (ERA)
- Formula: (Earned Runs / Innings Pitched) * 9
- Description: Measures the average number of earned runs a pitcher allows per nine innings. An ERA under 3.00 is excellent.
- Walks plus Hits per Inning Pitched (WHIP)
- Formula: (Walks + Hits) / Innings Pitched
- Description: Reflects the number of base runners a pitcher allows per inning. A WHIP below 1.20 is considered very good.
- Strikeouts per Nine Innings (K/9)
- Formula: (Strikeouts / Innings Pitched) * 9
- Description: Indicates how many strikeouts a pitcher averages over nine innings. A K/9 above 9.00 is impressive.
- Wins (W) and Losses (L)
- Description: The number of games a pitcher wins or loses. This is often seen as a team-dependent statistic.
- Saves (SV)
- Description: The number of games a relief pitcher finishes under certain conditions while maintaining the lead. A save is a key measure for closers.

- Description: Total number of innings a pitcher has thrown. Indicates workload and durability.
- Walks (BB)
- Description: The number of batters a pitcher has walked. Lower walk totals generally indicate better control.
- Strikeouts (K)
- Description: The total number of batters a pitcher has struck out. High strikeout totals indicate dominant pitching.
- Home Runs Allowed (HR)
- Description: The number of home runs a pitcher has allowed. Fewer home runs generally mean better performance.
- Quality Starts (QS)
- Description: A starting pitcher is credited with a quality start if he pitches at least six innings and allows three or fewer earned runs. It’s a measure of consistency.
Fielding Statistics
- Fielding Percentage (FPCT)
- Formula: (Putouts + Assists) / (Putouts + Assists + Errors)
- Description: Measures a fielder’s defensive efficiency. A fielding percentage above .990 is considered excellent.
- Errors (E)
- Description: The number of mistakes a fielder makes that allow a batter or base runner to advance. Fewer errors indicate better defensive play.
- Putouts (PO)
- Description: The number of times a fielder records an out through catches, tags, or force-outs.
- Assists (A)
- Description: The number of times a fielder assists in making an out. High assist totals are common for infielders.
- Range Factor (RF)
- Formula: (Putouts + Assists) / Games Played
- Description: Measures a fielder’s range and ability to get to balls. Higher range factors indicate better defensive range.
- Defensive Runs Saved (DRS)
- Description: An advanced metric that quantifies how many runs a player saves or costs their team defensively. Positive DRS values indicate above-average defense.
Advanced Metrics
- Wins Above Replacement (WAR)
- Description: Estimates a player’s overall contribution to their team, in wins, compared to a replacement-level player. WAR combines offense, defense, and base running into one metric. A WAR above 5.0 signifies an All-Star level performance.
- Batting Average on Balls in Play (BABIP)
- Formula: (Hits – Home Runs) / (At-Bats – Strikeouts – Home Runs + Sacrifice Flies)
- Description: Measures how often a ball in play goes for a hit. It’s used to evaluate a hitter’s luck and a pitcher’s effectiveness.
- Fielding Independent Pitching (FIP)
- Formula: (13 * Home Runs + 3 * (Walks + Hit By Pitch) – 2 * Strikeouts) / Innings Pitched + Constant
- Description: Estimates a pitcher’s performance based on outcomes they can control (strikeouts, walks, home runs), removing fielding from the equation. FIP is often seen as a better predictor of future performance than ERA.
- Weighted On-Base Average (wOBA)
- Formula: Combines all the different aspects of hitting into one metric, weighting each type of hit according to its actual run value.
- Description: A comprehensive measure of a player’s offensive value. A wOBA above .400 is elite.
- Exit Velocity and Launch Angle
- Description: Measures the speed and angle at which the ball leaves the bat. These metrics are used to analyze a hitter’s power and ability to produce extra-base hits.
