Unfortunately in all team sports whether a team wins by one or a hundred it only counts as one win. Been that way forever and I doubt it will change. However, with all the rule changes in baseball, who knows. Maybe the powers that be will come up with a rule that if a team wins by a certain number of runs it will count as 2 wins. I seriously doubt that will happen, but I also seriously doubted they would ever start extra inning games with a runner at second, so who knows?
