Generally the designated runner is to be used for the catcher when there are two outs, sometimes the number of outs is not important. The PURPOSE of the rule is to allow the catcher to put his equipment on sooner and speed up the game. Some leagues use the designated runner for both the pitchers and catchers. This allows the pitcher and catcher to also rest. In addition it gives a player the opportunity to participate who is not in the line-up.
