I suppose it could be argued that fear plays a large role in hitters being able to wildly succeed in all three; most guys who take a ton of pitches are going to see two strikes just by virtue of seeing a lot of pitches.
It has to be an elevated ability to determine which pitches one can handle. Being able to put bat on ball being a lesser talent to being able to discern which pitchs are the one that can be really handled. So, a Bonds, Pujols, Thomas, Bagwell, or Rodriguez see a pitch that another, lesser batter, might think is imminently hittable and pass on it as they inherently know they won't be able to drive it.
