By guest author: Nick Dixon

On Base Percentage (OBP) is a vital baseball statistic that tells how effectively a batter is getting his job done at the plate. On baseball percentage is often referred to the OBP. On Base Percentage is often referred to as the "on base average" or OBA.

What is On Baseball Percentage?

OBP is a statistic expressed in a three digit number that shows how often reaches first base. The OBP represents every way a batter can gets to first base for any reason other than a fielding error or a fielder's choice. On-base percentage is the measure of the number of times a player gets on base by getting on base with a hit, by drawing a base on balls, and by being hit by pitch. The expressed as a percentage of his total number of plate appearances.

How is calculate OBP?

OBP is calculated using the simple mathematical formula. To calculate the OBP you first add the total number of hits, walks and times the batter is hit by a pitch. You then divide that total by the total number of at-bats, walks, times hit by a pitch and sac flies..

OBP is calculated using this formula:

(Number of H + BB + HBP)

Divided by

(Number AB + BB + HBP + SF)


Symbols used in the formula above:

H = Hits

BB = Bases on Balls (Walks)

HBP = Hit By a Pitch

AB = At bats

SF = Sacrifice Flies

I hope that you have a better understanding of OBP after reading this article. I really appreciate you taking the time to read it. Good luck this season, Nick.
