When a batter hits an obvious double off the wall, the first baseman is supposed to trail the runner to second, in case the runner rounds the bag too far, or, as in this case, the relay gets bobbled. Rizzo was a spectator. He could have covered the fumble, Ohtani does not advance to third, the Sac Fly never happens, Yanks keep the 2-1 lead. I have seen Vaughn in action often, and he makes that play.
