The pitcher's hitting prowess isn't even a factor and any major league club who doesn't have a superior available pinch-hitter in the 5th inning of a game is in sorry shape, indeed. You say that you live in Georgia, like me, so you must be familiar with the hitting capabilities of pitchers like John Smoltz, Tom Glavine, and many others like them. They make that decision even MORE difficult. Atlanta is unique in having four front-line starters. They're not totally incompetent with the stick, but none of them hit for themselves in any situation where a pinch-hitter would normally be called for.
None goes up there hacking away when it's time to lay down a bunt.
None gets pitched to in the same way that real hitters get worked. That's what I call strategy. He consistently gets out-managed in the playoffs and is fortunate that he has the luxury of a loaded ball club. In the particular situation to which you refer, it was an extra-inning game where the only available position player was Rafael Belliard. Belliard is one of the weakest-hitting position players in the game, but is invaluable for his defensive versatility.
