It is a combination of 3 different stats. They are OBP/SLG/OPS, which mean
On Base Percentage (OBP)
Slugging Percentage (SLG)
OBP Plus SLG (OPS)
Here is the formula for each one.
On Base Percentage (OBP) is used to determine how often a batter reaches base safely divided by his number of plate appearances.
[Hits (H) + Walks (BB) + Hit By Pitch (HBP)] / [At Bats (AB) + Walks (BB) + Hit By Pitch (HBP) + Sacrifice Flies (SF)]
Slugging Percentage (SLG) is used to determine how much power a batter has
Total Bases (TB) / At Bats (AB)
On Base Percentage Plus Slugging Percentage (OPS) is exactly that:
OBP + SLG
This statistic is used to determine how well-rounded a batter is.
OBP stands for On Base Percentage
It is a defensive statistic that stands for "Assists"
Put Out *Pickoff
ROE Reached On Error
Runs batted in and on base percentage.
If it's an abbreviation for a statistic, it stands for Total Bases.
'IN' stands for 'innings' and is usually seen in a line of statistics for a pitcher.
OBP stands for On Base Percentage
Baseball and its not even close.
AVR is usually termed as AVG which stands for the players batting average. HR is the amount of home runs. RBI represents runs batted in. OBP shows a players on base percentage
On Base Percentage
I do not believe there is an "RE" statistic in baseball. There is an "ER" stats and that refers to "Earned Runs".
