OFFICIAL BASEBALL RULE 7.13
Collisions at home plate
A runner attempting to score may not deviate from his direct pathway to the
plate in order to initiate contact with the catcher (or other player covering
home plate). If, in the judgment of the umpire, a runner attempting to score
initiates contact with the catcher (or other player covering home plate) in
such a manner, the umpire shall declare the runner out (even if the player
covering home plate loses possession of the ball). In such circumstances, the
umpire shall call the ball dead, and all other baserunners shall return to
the last base touched at the time of the collision.
Rule 7.13 comment: The failure by the runner to make an effort to touch the
plate, the runner's lowering of the shoulder, or the runner's pushing through
with his hands, elbows or arms, would support a determination that the runner
deviated from the pathway in order to initiate contact with the catcher in
violation of Rule 7.13. If the runner slides into the plate in an appropriate
manner, he shall not be adjudged to have violated Rule 7.13. A slide shall be
deemed appropriate, in the case of a feet first slide, if the runner's
buttocks and legs should hit the ground before contact with the catcher. In
the case of a head first slide, a runner shall be deemed to have slid
appropriately if his body should hit the ground before contact with the
catcher.
Unless the catcher is in possession of the ball, the catcher cannot block the
pathway of the runner as he is attempting to score. If, in the judgment of
the umpire, the catcher without possession of the ball blocks the pathway of
the runner, the umpire shall call or signal the runner safe. Notwithstanding
the above, it shall not be considered a violation of this Rule 7.13 if the
catcher blocks the pathway of the runner in order to field a throw, and the
umpire determines that the catcher could not have fielded the ball without
blocking the pathway of the runner and that contact with the runner was
unavoidable.

第一、跑者用肩膀、雙手、手肘、手腕等部位，衝撞、推擠捕手，將被視為違反規則，但
滑壘不在此限。
第二、捕手除非持球，否則不能擋住跑壘路線，要是違規，跑者就會被判定得分。不過，
要是捕手準備接球，不在此限。
至於捕手是否準備接球、是否擋在跑壘線上，則由裁判認定。必要時，可以觀看慢動作重
播，認定是否違規。
最後,這規則會先試用一年,看實際操作後再來決定是否成為正式規定
