Yes. Second and third base are considered scoring position because a runner should be able to score on a single to the outfield.
The "keystone" in baseball usually refers to second base. It's called such because it is important in scoring (since a runner on second is in "scoring position") and because it's a key defensive position.
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.
It's a sacrifice fly. The batter is credited with an RBI, and the at-bat does not count against his batting average. The runner on second is inconsequential to the scoring decision.
A runner on first base with no outs has a 43 percent chance of scoring; a runner on second base with one out, say one who has been advanced there by a sacrifice bunt, has only a 45 percent chance of scoring. So the sacrifice increases the chance by only 2 percent! A runner who successfully steals second base with no outs, however, has a 60 percent chance of scoring a run-decidedly better odds.
Second base is considered scoring position because any solid single should score that run. So, when a runner is on second and the team gets it's third out, it is often called "stranding a runner" but occasionally for flair someone might say they died at second, meaning they didn't score and the inning is over.
Fielder has the right to occupy the territory necessary to field the ball, runner must give right of way to the fielder. In this case, runner is out.
No. You can't even touch a base out of order. If you pass a runner (and touch the next base before he does) you are out.
If the ball is hit straight back to the pitcher, the throw would always go to first base. The runners on first and second will have been leading off their bases which means they will get to the next base quicker than the batter will get to first base.
Runner attempting a steal from first, or a runner caught returning to second base.
if he interferes with the runner that would be called obstruction
No. Any base runner that gets on base and scores is charged to the pitcher that pitched to him, regardless whether the batter reached base by a force out, error, catcher's interference,etc.
