No rules against it, but the Cubs could just take the walks until they got a safe lead, and then swing at every pitch even if it was 5 feet outside in order to strike out and end the inning. and then the cardinals miss the 3rd strike on purpose so it goes to the backstop. Then the Cubs' batter doesn't run to first base, and Molina doesn't go back to retrieve the ball. It'd be hilarious. That would be fun to watch.and Mark DeRosa's dad gets into fights with other team's dads.
