presumably you want to search all tables, so use a union

  SELECT 'mens', score FROM soccer_mens
     WHERE gameDate = yesterday" to get
 UNION ALL
  SELECT 'womens', score FROM soccer_womens
     WHERE gameDate = yesterday" to get
 UNION ALL
   et cetera

the literal in the result set tells you which table the row came from
