You make the call #3

1 out
R1 on First.
Batter hits ball directly towards 2nd basemen who is playing about 5 feet behind the baseline.
R1 leaps over the path of the ball but never touches the ball and never touches the second basemen - no contact of any kind.
The 2nd basement stops her advancement towards the ball because of the runner and in fact bobbles the ball partly due to losing track of the ball while R1 jumps over it. But NO CONTACT. It was the fielder's choice to stop.

Umpire calls R1 out for obstruction. Is he correct?

 

There does not have to be contact in order to call obstruction. I would say he/she was OK in calling the play the way he/she did.

 

Obstruction

That same situation happen to my team the CALL is WRONG there is NO OBSTRUCTION the runner also has the right to run through the baseline as long they do not touch the fielder or the ball

 

I believe you are wrong concerning high
school rules.

 

This is the spirit of the rule: "Runner’s interference occurs anytime the runner’s actions interfere with the defense’s ability to make a play on the ball. If, in the umpire’s judgment, the runner unintentionally interferes with a fielder attempting to field a ball in fair or foul territory, or with the fielder’s throw, then the runner is out."

 

Same situation

We recently had the same situation. The difference for us was that the 2nd baseman and the runner did collide. Ball was lost and bobbled around in the confusion.
Like the situation above, the fielder stopped. We were told that had she continued in her fielding motion, interference was the call. But since she stopped her motion , there was no interference and the runner was safe.
It would seem that physical contact is not the deciding factor, but movement is.
BTW, this was high school ball as well.

 

Forgot to say the organization level was a college game.

 

This is a had to be there call.

If the fielder had to stop, hesitate or alter her attempt at the batted ball to keep from running into the (runner) then interference should be ruled.

It is always best for the fielder to make contact with the runner that way judgement is not necessary in making this call.

Contact is not required to have interference, but it sure makes it an easier call to make.
