Ok, so as long as a defensive plyr is making a play to get batter out, batter must b n the baseline at that time?
Baseline and basepath are 2 completely separate things. The baseline is a direct line between 2 bases and has little to do with much in the rules other than being foul lines between home and 1st and 3rd. Basepath is set by the runner and can be literally anywhere on the field. The only time a runner is restricted to 3' either side of the "basepath" is when a play is being attempted on them, and at that point the basepath is defined as a straight line between their current position and the base the runner is attempting to advance to.
N nsa sanction, if batter hits what he thinks is a hr but ball stays in, he heads to dugout (3rd base side) then realize ball is playable, then comments to run to 1st but cuts across field at least 5-6ft n front of home plate, is this legal?
I have seen a batter mash the ball deep, run to 1st and slide into 1st. Pop up and realise they can still advance and run to the pitching rubber and slide in (He got confused) and then run into 2nd base and slide into 2nd before the ball came back to the infield. He probably could have made it all the way around if he hadn't been such a noob. 3 nice slides though and surprised the hell out of the pitcher.
What determines a defensive player attempting to make a play on the BR? For example, if someone hits a double, but instead of rounding 2nd to go to 3rd they continue to run out to left field... if an infielder gets the ball and begins to chase them, does that mean the BR has to then run directly toward 3rd? Or does the defense have to be within a certain distance?
Lets say a runner on 3rd, batter hits the ball at pitcher, pitcher knocks it down but batter dont run thinking he is out anyway then heads to dugout meanwhile runner on third trys to go home, instead of pitcher gettin guy out at first he trys to make a play at the plate, batter then decides to attempt to run to 1st, lets say batters dugout is on third base side, now what?
