Proper protocol is to only play the anthem one time at a sporting event. In a baseball double header the anthem is only played once unless it is a split day night event. In that case it is treated as 2 different events. I've been to a number of NCAA tourney double headers and the anthem was only played at the beginning of the first game. Sure the anthem can be played twice bit it shouldn't.

That is the correct spelling of "double" (twice as much or as many, to fold in half).
