Good point, hitters always have a job to do and with two outs no baserunners... that approach is to drive the ball for HR or extra bases. So even the 2 strike approach can change based on the situation. It's just there are a lot of power hitters that don't change their approach no matter what the situation., We all see them, no baserunners bottom of the ninth and their team is down by 2 or 3 runs. They take the big HR swing because they have no 2 strike approach and strike out.
