Right I think this allows the team to rotate the 8th/9th inning between those three which *should* keep them fresher for the rest of the year, as Miller has closed games this season.
And that bumps everyone else back, so fewer outings or less high leverage outings for Mears, Koenig and Anderson who have performed well, but they can be the 6th/7th inning guys or late innings in less close games.
Again, assuming health, and everyone continues to perform as they have this year.
