That has to be the dumbest rule ever put into play. Here's what the rule is: starting in the 11th, teams start with runners on 1st and 2nd, and the next batter in the lineup bats. For example. Team USA last night had the 8th batter in the lineup at second, 9th at first, and the leadoff man at the plate. How hard is that? Put down a good sacrifice bunt (your leadoff guy is usually your best bunter), and now you have guys on second and third, with one out. A hit scores one, extra base hit scores two, a sac fly sores one also. That seems like a pretty easy way to win a ball game.
It reminds me of the College Football overtimes; Really high scoring, but also terribly boring to watch.
