If this were true then pitchers would have the highest OBP in the majors. If a batter never swings in the majors they will soon be striking out every appearance. It won't take long to figure out the guy won't swing at strikes. That's why even when pitchers bat they will swing at pitches. I believe you missed the point RockCo was trying to make, obviously the batter would swing after taking a strike, not just stand up there and watch every pitch. If a batter takes until he gets a strike the chance of getting ahead in the count would increase compared to not taking until you get a strike. It seems pretty cut and dry that making the pitcher throw a strike before swinging would increase the odds of getting a walk.
