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/善意的滑壘＝
要件1:觸壘前開始與地面接觸滑壘
要件2:意圖/能用手或腳觸壘
要件3:意圖/能在滑壘之後留在壘包上（由於本壘碰到就得分，不需要套這個要件）
要件4:沒有變向想跟防守員發生接觸
大部分的時候我們都把焦點放在要件3
只要能留在壘包上就是合法
但是Rizzo很明顯，從線外跑到線內
變向來跟Diaz碰撞
要件4在一壘跑往二壘可能有點模糊，畢竟沒有很明顯的白色壘線
但是三壘往本壘就很明顯了
還是某大大要來解釋一下這條？

我覺得沒什麼變向欸 他瞄捕手瞄的很準

很明顯的變向啊 原本跑外側 滑壘切內側

棒球發明國熊說合法就合法

Sxxxx:這個play沒有誤判的可能

考慮增個TB5吧 防守員視線能預見跑者有意作接觸一般二壘手都能看見可能接觸 Diaz當天連視線都沒法顧及

沒用啦 我當時就跟他這麼說他就裝沒看見啊他會跟你說裁判說沒問題就是沒問題然後隔天他褲子內褲就都沒了

直接說結論。球員、教練、裁判都不清楚標準看國外媒體人怎麼說的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.

我直說八 這條的用字是"when" 代表滿足1234點是合法滑壘的充分條件 => 有滿足就合法 (沒滿足未必不合法)所以rizzo沒滿足3 不代表就是不合法
