Why wouldn't the batter by on first?....if they hit a grounder to SS and she is interfered with by runner from 2B, the batter still gets 1st, why not on a pop up?TMIB, I will respectfully disagree.
Runner on 3B, 1 out. Foul fly ball towards third. Runner makes contact with the fielder causing her to alter her path to get to the ball. Fielder makes an ESPN web-gem diving catch. By your interpretation you have no interference and batter is out and runner staying on third with now 2 out. By my interpretation (and by rule per my argument), I have interference, 2 out, no runners on base and 0-1 count on the batter.
There was clearly interference that occurred, it needs to be called immediately and whether or not the catch is made has no bearing.
