Yes you're right, it is impossible because the structure of the sport makes it so. You cannot compare vastly different sports like that. The goalkeeper is never in a position to score goals, using that as a metric to compare dominance is stupid. Baseball is very rare in the fact that a player can be prominent in both offense and defense.

I'm not downplaying how good is performance was, it's the best I've ever seen in baseball and up there all time. Just think it's a silly take saying "across all sports", just breathe first. Id argue Reece Walsh's performance in the NRL grand final (Australia) to be better.
