No. For it to be a sacrifice fly, a runner must score.
If the batter is tagged out before he reaches first base it is still considered a force out and the runner cannot score, however if the batter crosses first base safely and then is tagged out, the run counts if the third base runner crosses home plate before the batter is tagged out.
If there are less than 2 outs, the runner from 3B would score on the play.However, if there are 2 outs, the runner on 3B would not score, because the third out was a force out. If the third out is a force out, at any base, no run would score.
If there were no outs in the inning, the runner on third would have the opportunity to score it the player chooses to run.
The batter is credited with a single. The runner is out and play is dead.
A runner can slide into any base.
The lead runner is the runner at the base closest to home plate when there is more than one runner on base. If there are runners on second base and third base, the runner on third base is the lead runner. If there are runners on first and second, the runner on second is the lead runner. If there is only one runner on base, there is no lead runner.
No the run does not count. An out at any base would be a force out and no runs can score, If the runner scored and the third out is made because a runner is called out on an appeal play such as failure to retouch on a fly ball out or a runner missing a base the run would count
