I don't believe JD would have scored had the ball traveled down the RF line unimpeded by the stool. The proper ruling of the play would have put JD at third base, I believe. Even if that were not the case, I still don't believe this play decided the game. Robles did. It is largely inconsequential yet I still feel some odd compulsion to die on the hill of "it clearly hit that fucking stool, guys." If you don't see that ball hitting the stool, you're not looking with your eyes.
Anywho, may Eovaldi mow pricks down and homefield advantage shift our way. Have a glorious game 2, SOSH.
