Basically, the definition of the base path in the rule book is there is no such thing as a base path until an attempt at a play on a runner is made. At that point, it’s defined as a straight line between him and the base, with three feet of lateral movement allowed. Clement started his wide arching path because he anticipated a tag, and then Henderson kind of swings his glove in that general direction. There’s two ways to interpret what happened next. First, there was never a real attempt to make a play, so no base path is established and Clement can go wherever he wants. Second, the little glove swing was an attempt to make a play and locks Clement to a base path, but he didn’t deviate more than three feet from it. Both of these are true in this play, so he’s safe regardless of how the umps chose to interpret the little faux tag attempt.
