Whoever has been brainwashing managers to follow these unwritten rules as if they've been handed from the Lawgiver needs to be found and dealt with. Lineups need to be constructed in a way that gives players the best opportunity for them to succeed. Putting inferior hitters high in the order just to "break up the lefties" is ridiculous. He's effectively saying he's willing to give up the potential for more runs early in the game in exchange for a marginal benefit later in the game when the other team brings in their lefty specialist for 1 inning. Now I realize there's more to managing than just constructing a lineup. But it just bugs me to no end how the management of this team seems hell-bent on marginalizing its best offensive players in favor of "strategery."
