Yes. OBP: Add up all plate appearances. This is every time you come to bat. Subtract sacrifice bunts. The number you get is your total at bats. Add up all the times you reached base safely, which should include hits, walks and the number of times you reached base by a hit by pitch. This total does not include the times you reached base because of an error or a fielder's choice. Divide the times you reached base safely by your total at bats. Round to the third decimal place.
yes
Yes, but it will not effect his batting average
No. Only hits, walks, and times hit-by-pitch improve a hitter's OBP.
The official formula for on-base percentage is (Hits + Walks + Hit by pitch) / (At-bats + Walks + Hit by pitch + sacrifice flies). Reaching base on an error goes against your BA and OBP, as it doesn't count as a hit but counts as an at bat.
No, BB is for a base on balls or walk. Hit by pitch would be HBP.
According to Baseball Reference, in the 2007 season there were 942 batters hit by a pitch in the National League and 813 batter hit by a pitch in the American League.
OB as in OBP is on base percentage which is the average of the number of time you reach base in some why, other than an error, such as walks hits or you get hit by a pitch (HBP).
NO
If a batter is hit by a pitch and the umpire determines he was "leaning over the plate", or "moved into the pitch" then he may not be awarded first base and the pitch will be called a strike or ball
HB means hit batsmen: the names of the batters the pitcher has hit by a pitch. HBP means who the hit batsmen are.
Yes, if you are the batter.
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.
