Frequently Asked Questions
How is batting average calculated?
Batting average equals total hits divided by total at-bats, expressed as a three-decimal number like .300.
How does OBP differ from batting average?
OBP includes walks and hit-by-pitches in addition to hits, divided by at-bats plus walks, hit-by-pitches, and sacrifice flies, giving a fuller picture of how often a player reaches base.
What is a good OPS?
An OPS (on-base plus slugging) above .800 is generally considered very good, while above .900 is excellent at most levels of competitive baseball.
