As per the Baseball Ontario Return to Sport Protocols, 2 events are permitted on one baseball diamond. This means that 2 different groups, of not more than 10 each, can participate in separate practices on the same field. One team could split into 2 such groups as long as they stay separate throughout the practices. Everyone must stay in their own group and there can be no players, coaches or other persons participating in both events even if the two groups came from one team.
Any equipment used by one event or group must be cleaned/sanitized prior to use by the other event or group, including if both events are being run by the same team (i.e. a split squad practice). All activities for both events must adhere to the distancing measures required by the provincial government, the relevant municipality and public health authorities and the Baseball Ontario Protocol.
