Little League courtesy runner?

[soonerfan]

depends on your league's specifics. most of the time it's the pitcher and catcher. where some get sticky is the catcher may be ran for only once there is 2 outs. also, some allow that the last batted out run, others say it must be an available, non participating sub. plus, one courtesy runner per runner, please. i.e., carl lewis can't run for both david wells and ron karkovice in the same game. hope this makes sense...enjoy!
