I understand the disruption because of injuries and callups, and the need to use all players and get their work in, but
Having Mercado the classic leadoff man batting 6th and 7th let alone 8th or 9th. I could understand 3rd because he is one of the leading hitters.
And light hitter like Tovar bat 5th and 6th and Mejia bat 4th, 5th and 6th, and Baron the weakes hitter on the team batting 6th.
