From KSHSAA:
A rolling schedule means that once a game is completed the amount of time between games will be enough for field crews to get the field ready (varies based on site) and team infield warm up. While facility management is getting the field ready, teams can run/stretch/throw in the outfield area or in other areas designated by host management. Once the field is ready for play the home team has no more than 10 minutes of infield warm-up followed by the visiting team having no more than 10 minutes of infield warm-up. Once this is completed, do introductions and start the next contest.
