I don't usually look at games as "gravy" games, but tomorrow might be as close as they come.
With Hall on the IL and Mears, Ashby, Koenig, Uribe, and Megill all having pitched yesterday and today, the bullpen is going to be pretty thin tomorrow. I doubt if any of those 5 will be used tomorrow. with the doubleheader against the Cubs on Monday. Quintana might have to go at least 6 even if it means taking one for the team.
It might also be a good idea to give Frelick a day off if he tweaked his knee or hamstring again.
Hope for Quintana to be great and for the makeshift lineup to put up a bunch of runs and if they don't just live to fight on Monday.
