According to MLB Rule 6.01(j), a bona fide slide "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."
合法/善意的滑垒＝
要件1:触垒前开始与地面接触滑垒
要件2:意图/能用手或脚触垒
要件3:意图/能在滑垒之后留在垒包上（由于本垒碰到就得分，不需要套这个要件）
要件4:没有变向想跟防守员发生接触
大部分的时候我们都把焦点放在要件3
只要能留在垒包上就是合法
但是Rizzo很明显，从线外跑到线内
变向来跟Diaz碰撞
要件4在一垒跑往二垒可能有点模糊，毕竟没有很明显的白色垒线
但是三垒往本垒就很明显了
还是某大大要来解释一下这条？

我觉得没什么变向欸 他瞄捕手瞄的很准

很明显的变向啊 原本跑外侧 滑垒切内侧

棒球发明国熊说合法就合法

Sxxxx:这个play没有误判的可能

考虑增个TB5吧 防守员视线能预见跑者有意作接触一般二垒手都能看见可能接触 Diaz当天连视线都没法顾及

没用啦 我当时就跟他这么说他就装没看见啊他会跟你说裁判说没问题就是没问题然后隔天他裤子内裤就都没了

直接说结论。球员、教练、裁判都不清楚标准看国外媒体人怎么说的Unfortunately, it’s not very clear when viewing it that it is illegal. The players, coaches, managers and even the umpires aren’t clear on how to interpret andenforce these rules. That’s a problem, one that needsto be addressed as quickly as possible. And by contradicting on Tuesday what the umpires determined on Monday, the league has essentially admitted that to everyone involved.

我直说八 这条的用字是"when" 代表满足1234点是合法滑垒的充分条件 => 有满足就合法 (没满足未必不合法)所以rizzo没满足3 不代表就是不合法
