I would concede you probably shouldn't be stealing or pulling hit and runs, but no one should be complaining about swinging the bat. I tend to think batters hack away too much and should work the count, but on a 3-0, if you see your one pitch, then take the swing. If the pitcher doesn't know that is your pitch, how is that on the batter?
And what is he swings and grounds out? Is the pitcher going to complain?
