Runner Interference After Fielder Has Booted a Ground Ball

[Mudder]

OBR, R2, hard hit ball to SS, bounces off fielders glove and to his right a foot or two, just as runner is running by to 3B, SS has to reach to his right to pick up the ball and his hand gets tangled up in the runners legs as he's trying to pick up the ball, so he is late in picking it up and has no play at 1B

RI or not?

 

and cite the rule reference

6.01(a)(10) "It is interference by a batter or a runner when: (10) He fails to avoid a fielder who is attempting to field a batted ball.  PENALTY FOR INTERFERENCE: The runner is out and the ball is dead."

MLBUM Interp 58(4) clarifies that "attempting to field a batted ball" includes a deflection off the fielder (that doesn't hit the runner) which is "within the fielder’s immediate reach".

MLBUM Interp 58 (4) With the bases loaded, batter hits a sharp ground ball that deflects off of the shortstop and starts to roll away from him. As the shortstop starts to go after the ball, the runner from second collides with the shortstop.

Ruling: After the ball deflects off the shortstop, if the ball is within the fielder’s immediate reach, the runner must avoid the fielder, and if contact occurs under those circumstances, interference shall be called and the runner declared out. (In this situation the fielder is still considered “in the act of fielding” the ball and has not “missed” as described in the Comment to Official Baseball Rule 6.01(h).) However, if the ball is not within reach of the fielder after it deflects off the fielder (i.e., the fielder must chase after the ball), the fielder must then avoid the runner, and if contact occurs under those circumstances, obstruction shall be called under Official Baseball Rule 6.01(h)(2).
