If a runner does not engage in a bona fide slide, and initiates (or attempts to make) contact with the fielder for the purpose of breaking up a double play, he should be called for interference under this Rule 6.01. A “bona fide slide” for purposes of Rule 6.01 occurs when the runner:
(1) begins his slide (i.e., makes contact with the ground) before reaching the base;
(2) is able and attempts to reach the base with his hand or foot;
(3) is able and attempts to remain on the base (except home plate) after completion of the slide; and
(4) slides within reach of the base without changing his pathway for the purpose of initiating contact with a fielder.
...
Notwithstanding the above, a slide shall not be a “bona fide slide” if a runner engages in a “roll block,” or intentionally initiates (or attempts to initiate) contact with the fielder by elevating and kicking his leg above the fielder’s knee or throwing his arm or his upper body.
