Frequently asked questions

Why is OBP more important than BA?

A walk has nearly the same run value as a single. A batter who hits .260 but walks a lot can be more valuable than one who hits .280 but never walks. OBP captures this — it's why player evaluation shifted strongly toward OBP in the Moneyball era.

Do sacrifice bunts count against OBP?

No — sacrifice bunts are excluded from the OBP denominator, like batting average. Sacrifice flies are included, however.
