If you can hear thunder, you can get hit by lightning. Take shelter immediately. If you cannot find a sturdy, fully enclosed building with wiring and plumbing, get into a metal-roofed vehicle. Seeking shelter in baseball dugouts is not safe. Do not stand under tall objects like trees or be on the baseball fields. Stay inside for 30 minutes after the last rumble of thunder.
We would expect all games to be suspended until the 30 minutes and if it is still rumbling with thunder or you see lightning, please leave the park.
