What options? If the runner is on second and there are two out, the opposing team isn't going to be trying too hard to hold the runner, because the run that matters is at the plate. There aren't going to be infielders moving around opening holes. Maybe if the runner was on first, but not so much with one on second. I don't see how this is an advantage, and certainly not better than having that runner already in the run column. And the next batter isn't required to try and homer, they can single, take a walk, etc. And again, some people see runners still on base and feel that it is somehow maintaining the rally better, but the fact is that is perception obscuring reality. The homer is better than any other hit in any situation, unless you are the pitcher.
