Teams have been known to do this, but it always ends up happening in long extra-inning games when benches and bullpens are both nearly emptied. I can't recall a team doing it just for the heck of it in a "normal" situation.
Bill James discusses the issue on p. 183-4 of the [u:3966d55254]Bill James Guide to Baseball Managers[/u:3966d55254]. He says that Whitey Herzog "used this trick at least five times in the late 1980s." James then goes into depth about an incident on May 15, 1951. White Sox manager Paul Richards moved his reliever on the mound to 3B, in order to bring in a lefty against Ted Williams. The lefty did in fact retire Williams, and the original pitcher then returned to the mound, with the backup 3B coming off the bench to play there.
Naturally, if Teddy had hit the ball to 3B*, the White Sox probably would have been screwed. And as James points out, there's another big factor: You've taken the original position player out of the game.
[quote:3966d55254]The value of the platoon edge for one hitter is about .025 hits... So in order to gain 25 points on Ted Williams, Richards replaced a .326 hitter [Minnie Minoso] with a .263 hitter [Floyd Baker]. The game went 11 innings, and Baker went to bat twice.[/quote:3966d55254]
Of course, if you do it for more than one batter, you can potentially get more platoon advantage... but you're also increasing the chance that an evenly-balanced batter will come up, not to mention the chance that the ball will be hit to the pitcher playing out of position.
To me, everything would have to be aligned perfectly: You'd have to have pitchers who utterly shut down the same-side batters; you'd have to be really sure that the opponent has no plausible pinch-hit option; and you'd have to have an "escape plan" where you can revert back to a real player if you need someone out there who can field a ball.
[i:3966d55254]* Which, to be fair, he hardly ever did. But SOM does not reflect this.[/i:3966d55254]
