Avoiding INT

[RKBUmp]

I believe this is the rule you want.

12.19.2.1.4.1.a When the defensive player, while watching the flight of a
ball, bumps a base runner who is standing on a base and fails to make a
catch on a catchable ball, the base runner shall not be called out unless
the hindrance is intentional. A base runner must vacate any space
needed by a fielder to make a play on a batted ball, unless the base
runner has contact with a legally occupied base when the hindrance
occurs. This is an exception to the rule that defensive players must be
given the opportunity to field the ball anywhere on the playing field
without being hindered.
