35+ League
  1)  Teams can have 5 players on the roster younger than 35 years of age.
  2)  Players younger than 35 can not pitch in playoffs and only during regular season games if approved by other team
  3)  Players under 30 years of age can not play the position of catcher or short stop unless approved by other team
  4) Game days are typically Sunday only with playoffs on Saturday/Sunday.   Make-up games maybe on any day or evening.

Generally we announce players playing in positions before game time and seek approval.
