Baseball Cheatsheet

I wouldn’t say that I’m a big baseball fan anymore, but I’ve wanted to understand the sport better for awhile now.

Using the power of the internet, I compiled this short cheatsheet (with formulas!) to understand the player boxscore better.

AB – At Bats

At Bats count the number of times a player bats, excluding walks, sacrifices, and hit by pitch.

R – Runs

A run is scored when a player safely reaches home plate.

H – Hits

Hits count the number of times a player reaches at least first base on a successful hit.

RBI – Runs Batted In

Runs Batted In count how many runs a player causes to score with their hits or plays.

BB – Base on Balls

Base on Balls (AKA Walks) count the number of times a player reaches first base after four balls are pitched.

SO or K – Strikeouts

Strikeouts count the number of times a player accumulates three strikes during an at bat.

AVG or BA – Batting Average

Batting Average is the ratio of a player’s hits to their at bats.

OBP – On-base Percentage

On-base Percentage measures how often a player reaches base via hits, walks, or being hit by a pitch.

SLG – Slugging

Slugging Percentage measures the total bases a player earns per at bat.

OPS – On-base Plus Slugging

On-base Plus Slugging combines on-base percentage and slugging percentage to assess overall hitting performance.

OPS+

OPS+ adjusts OPS for league and park differences, with 100 being average.
