Runner's Intereference/Obstruction

[NM FP Ump]

You had the IFF rule in effect, but is it applied here? I don't think I would have called the infield Fly. Since F3 was playing in front of 1st, and the ball was hit 5-10 feet behind 1st base, near the foul line, we have to judge if she could have made a catch with ordinary effort. Obviously, F4's effort to record an out on the pop-up does not qualify as "ordinary effort", "… The 2Bman makes the catch while sliding", so I don't think the IFF can be called.

The offense has to give the defense a chance to field the ball, and R2 (runner on 1st) interfered with F3's attempt to field the ball, so I would call Dead Ball, Interference, R2 is out, R1 returns to 2nd and B/R is awarded 1st.
