Rule Clarification - Pitchers In the Batting Lineup

I need to add a new rule to our rule book.  Pitchers are allowed to be used as pinch hitters but they cannot be inserted into the batting lineup unless they have enough at bats to be qualified as a batter.  I don't know if there are any instances of this, but I would bet some 1800s pitchers may qualify as batters.

For instance, 1886 Bob Caruthers can hit a ton (201 OPS+).  You cannot draft him as a pitcher and then insert him into the lineup as a regular or part time batter.  However, he can be used for  pinch hitting duties if you want to risk injuries on the base baths.

This may sound like a good idea, but keep in mind if you have him as an active pitcher the computer AI will undoubtedly find a way to use him from time to time.  He does not sim well as a  pitcher (5.81 ERA, 1.57 WHIP with Rusty Kuntz last year) and one will have to weigh the risk.

Personally, i think it is probably worth it for a batting line of .334 / .448 / .527.  The following year in '97 he batted .357 / .463 / .547, albeit in more of a hitters park.

Earlier in the draft someone asked me if pitchers can hit.  I said yes, but I needed to qualify to close the loophole mentioned above.
