Yes an error counts as an at bat, but not a hit. You would be 0 for 1 on the play, but your on base percentage goes up because you have reached base safely. Errors can be committed on sacrifice bunts and sacrifice flies. If the official scorer rules a play a sacrifice bunt/fly and an error, the batter is not charged with a time at bat. On base percentage goes down when reaching base on an straight error.
Yes. It will be scored as an out. It will count as being on base though so it will not negatively effect an on base percentage.
No, because if the error hadn't occurred, the batter would have been out.
The run would not count since there are 2 outs and the fielder got the out at 1st base which is the only thing that matters in that situation with 2 outs regardless of the runners and regardless of any of the other circumstances of who is on base.
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.
Yes. While a sacrifice fly does not count against your batting average it does against your on base percentage. On base % = (hits + walks + hits by pitch) / (at-bats + walks + hits by pitch + sacrifice flies)
Only if there was an error on one of the plays, the batter might get credited for a sac fly, but reached base on error.
Yes. The only time it is not an official "At Bat", is if a batter reaches base on a base on balls, hit by pitch or catcher interference. A batter is also not charged with an "At Bat" if he hits a sacrifice fly (a fly ball out that results in a runner tagging up and scoring), or a sacrifice bunt that advances a runner or runners. He is also not charged with an "At Bat" if the batter reaches base as a result of an error on a sacrifice fly or sacrifice bunt.
That decisionis left up to the person who is the 'official scorer' for the game. If the batter turns and shows bunt before the pitcher throws he usually is credited with a sacrifice whether an error is committed or not. But if the official scorer thinks that the batter was trying for a base hit and not for a sacrifice he may score it solely as an error.
Usually, but not always. SAC is an abbreviation for a sacrifice, a play when the batter turns and bunts the ball in order to advance runners on base while being put out at first base. But, if the fielder makes an error on the play and the batter is not put out the official scorer can still credit the batter with a sacrifice.
No...a fielding error that allows the runner to get on base and that runner scores is not an earned run and does not count against earned run average.
