I believe that using the pitcher warmup option will make your replays a lot harder. Warming up pitchers is an element of strategy that most sim managers don't use, and it's a different game when you can match up immediately with any pinch-hitter the CM brings in or vice versa. The CM never makes a sub-optimal decision, which is why I let it handle my baserunning and throwing. I'm pretty sure it handles pitcher warmup the same way, and it is often going to be a step ahead of a human sim manager.

Always on the lookout for capable backup owners.
