Frequently Asked Questions

What is on base percentage?

On-base percentage (OBP) is a baseball statistic that measures a player's ability to reach base safely. It is calculated by dividing the sum of a player's hits, walks, and hit-by-pitches by the total number of their plate appearances excluding sacrifices.

Whats is On Base Percentage Formula?

The formula to calculate on base percentage is: OBP = (H + BB + HBP) / (AB + BB + HBP + SF). Where, H equals Hits, BB equals bases on balls, HBP equals hit by pitch, AB equals at bats, and SF equals sacrifice flies.a

What is a good on base percentage?

In baseball, a good On-Base Percentage (OBP) is typically considered to be above .350. An OBP above .350 indicates that a player is getting on base roughly 35% of the time they come to bat. However, what is considered "good" can vary depending on the context and position of the player.

What is OPS value?

OPS stands for On-base Plus Slugging, and it's a baseball statistic that combines a player's on-base percentage (OBP) and slugging percentage (SLG) into a single value to provide a more comprehensive measure of their offensive performance.

Does a HR count for OBP?

Yes, a home run (HR) does count toward a player's On-Base Percentage (OBP). A home run is counted in the "Hits" part of the numerator, so it directly contributes to a player's OBP. In this way, OBP accounts for a player's ability to reach base through various means, including hits, walks, and hit-by-pitches, with home runs being a subset of hits.
