Anyone who thinks a good hitter can't change his approach to generate a flyball in a sac fly situation should watch the replays of Chase Utley's stroke last night to tie the game.
Is it a dying art? Definitely. Is it a part of a complete hitters game? Fewer and fewer guys shorten up or choke up and produce a compact stroke these days.
But if you want to see a textbook example of a smart player with a complete game at the plate, watch that stroke Utley put on the ball last night.
