Of course. They did Bat you in to score. How you got on base to begin with doesn't matter.
A batter that reaches base due to an error and later scores is not counted as an earned run.
No, the run is credited to the error
The error stands as the batter reached a base safely.
Plate appearances is the total number of times a player has stood at the plate ... regardless of outcome. At-bats are counted when a batter either scores an 'out' or scores a 'hit'. If the batter receives a Base-on-balls, hit by pitch, or reaches base as the result of an error or Fielder's choice, it doesn't count as an at-bat. Batting average is figured as hits/at-bats. On-base percentage is figured as #of times on base / plate appearances This answer is wrong... If the batter reaches base as a result of an error or fielder's choice it still counts as an at bat, if the batter records an out that results in a sacrifice fly it does not count as an at bat. Also a base on balls includes the possibility of hit by pitch in its definition.
Yes, the batter would have been out if it were not for the error.
Usually, no. But the scorer may award an RBI if, in his or her judgment, the run would have scored even had the out been made. One example might be a routine, but deep, fly ball, where the runner would have scored even if the catch had been made. I think you might be asking this question the wrong way: If a run scores BECAUSE OF an error, then you don't get an RBI. However, it's entirely plausible to get an RBI on a play in which you reach on an error, as above, or an RBI groundout in which the runner would have scored from 3rd but the batter should have been retired. The question of whether you get the RBI is not a matter of whether the BATTER reaches via error, but whether the guy who scores, SCORES because of the error.
No, because if the error hadn't occurred, the batter would have been out.
No. If a player reaches base due to a fielder's error, the batter does not receive credit for a hit, but does get credit for an at-bat. Therefore, the batter's average will descend, but the batter's on-base percentage will increase.
There could be but I can't remember having ever seen one. A four base error would be an error that allowed the batter to score. I have seen plays where more than one player made errors which allowed the batter to score. I guess that could be called a four base error but I would think it means one defensive player made an error that allowed the batter to score.
That play would be called a 'fielder's choice'. A fielder's choice is a play where the defensive player that fields the ball attempts to put out a runner at another base instead of attempting to put out the batter at first base. No hit can be awarded on a fielder's choice but a sacrifice can be awarded if the batter had turned in the batter's box before the pitch in an obvious sign that they were going to bunt. An RBI can also be awarded if there was no error on the play.
A batter can get a hit.A batter can walk.A batter can get hit by a pitch.A batter can run out a drop third strike and make it safely.A batter can reach first base on an error.A batter can reach first base because of a fielder's choice to make a play elsewhere.
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.
