The top 2 hitters on my DD's team - AVG, SLG, and OPS - are also among the lowest in Ks (less than 10%). One has more HRs than Ks. The other has twice as many 2Bs as Ks.
My point is that the goal should be to be a good hitter - hit for average WITH power. You don't have to sacrifice one for the other. Develop a good swing that generates power, and learn to hit with that swing. Hit with intent to do damage, and have a calculated approach to your at bats. Be a predator.
I love watching my DD at the plate.
