I've seen this kind of boxscore a thousand times and I'm sick of it!

Vancouver ip h r er bb so bf era
Ortiz 5.0 4 1 1 1 6 19 2.13
Lidge L,3-7 1.0 1 3 3 2 2 6 5.04
Stanford 2.0 2 0 0 0 1 7 0.00

My Ace Starter is cruising along and gets pulled for a pinch hitter after only facing 19 batters. Then, my horrible bullpen loses the game. Why? Why? Why?

I have a five-man rotation, my bullpen is set on the aggressive side meaning the robot should make less moves ... so it must be the pinch-hitting settings. Where the hell do they have to be set to prevent this Grady-Little-in-reverse stupidity?
