I have found that some of my pitchers have around 2 pitches in which they can control well since the patch.
For instance, Brandon McCarthy was pitching, I couldn't locate a fastball to save my life...a few were crushed when they were located incorrectly. The same with the slider....brutal...kept hanging it over the plate.
So I threw my change and CB for strikes, and threw the FB up up up and mostly away just to show the pitch....and it mostly worked...pitching is must better and much more strategic post patch IMO.
