Sac bunts have limited use. Most of their use should come with guys like Neifi Perez or pitchers, and it should even be limited with the Neifi's of the world to close and late situations when you only need one run to tie or go ahead. Outside of that, it's one of the most overused plays in the game. Take our big man, Derrek Lee. Last year he hit 99 XBH. Assuming you have a speedy guy like Juan Pierre on first (and judging by the current crop of managers and GMs, that's likely), Lee is just as likely to hit an XBH as he is a single. Pretty much any extra base hit is going to score a run with Juan Pierre on any base. Pretty much any extra base hit has a good chance of scoring a run no matter the runner or his position on the basepaths. There are, of course, exceptions to that rule, but most of the time it works. So, I'm assuming we have a Juan Pierre-type leadoff hitter next year, in that he's fast (not assuming on-base skills, that's yet to be determined). Wouldn't you rather have the oppurtunity for Derrek Lee's XBHs to drive in 2 runs instead of 1?
