Interference?

[mbyron]

Different for OBR and FED.

OBR: No INT. The rule protects the first fielder, not just any fielder in a position to field the ball. It's INT if a batted ball touches a runner "before the ball has touched or passed an infielder" 7.08f. That's not the case here, play on.

FED: INT. It's INT if the runner "is contacted by a fair batted ball before it touches an infielder, or after it passes any infielder, except the pitcher, and the umpire is convinced that another infielder has a play" 8-4-2k. So if you judge that F4 has a play, the correct ruling is INT.

Don't know NCAA, sorry.
