We've all seen ab's where the hitter just battles and battles until he can get something to drive. We've seen the ones that work the count and work the pitch count. We've seen the ones that ruin the "pitchers pitches" and refuse to bite on those "pitcher's pitches". What do you look for in a good at bat?
And for the record, THIS is the best AB I've ever seen...and it's simply due to the mental aspect of it and the intensity. Was it a gimmick? Maybe, but out-thinking the pitcher is what I want to see. Making the PITCHER uncomfortable...you pull that off, and you win.
