INT or no call?

[Andy]

First of all....this is definitely a HTBT, umpire judgement call.

Based on the information you provided, here are some thoughts.

F4 had the right of way here because she was fielding a batted ball. R1 has to avoid F4. From your description, it sounds as though F4 chose to relinquish her right of way to R1. Had F4 stopped or checked up her charge to avoid an imminent (your judgement) collision, I believe the INT call would have been justified. This assumes that R1 is proceeding normally to second and did not do something purposefully (stutter step, for example) to place herself between F4 and the ball.

I would also consider the level of play for this situation. HS Varsity - I expect them to make the play even with the runner in close proximity. 10u or 12u could be a different story.
