Ahead of tennis courts reopening in parts of Long Island, Nassau County Executive Laura Curran emphasized the importance of only handling your own balls. If you and another player are from another household, she explained during a press conference last week, you can touch each others’ balls, but players should otherwise take every precaution to avoid coming in contact with balls of unknown origin. “You can kick their balls, but you can’t touch them,” Curran said to a giggling crowd.
