Yermín Mercedes of the Chicago White Sox generated some controversy when he swung on a 3-0 pitch (by a position player) to hit a home run in the ninth inning of a 15-4 game against the Minnesota Twins.  However, that was not the most egregious violation of the unwritten rule against showing up your opponent in this fashion.  Which player swung on and hit a home run off a 3-0 pitch late in the game off a position player (7th inning or later) with the largest lead?
