I've enclosed a screenshot of a pitching line from one of my recent games. This is actually the last game I played.
I'd typically like to see my starter get another inning if possible, but he came to the plate down a run with two guys in scoring position. I pinch hit for him.
Cattanach, who currently has my closing duties, was hurt in the ninth.
I think it's pretty normal, though, for teams I manage to use 3-4 different pitchers in the game. The league I'm playing right now has 4-man rotations, and I will carry 12-13 pitchers on my active roster. I use them all on a very regular basis.
