Three pitchers is huge for any team looking to go forward. You have to remember injuries, heat, sickness and in health (lol). You do have the rights to obtain a pickup players. There is a form on the ASA website, if you are looking at ASA Nationals. Not sure how NSA, USSSA, or Ponies work.
My team did initials fundraisers this winter which were geared specifically towards our goal of qualifing for Nationals/Eastern Nationals with ASA. We reached our goal for both Nationals and Eastern Nationals. What were are doing and have been doing since we solidified our goal is getting sponsorships and donations to help us defer the cost to the parents/players. At this point we have three out of the five nights of our hotel cost covered for 14 players and two coaches. Not bad, and we still have a couple of more weeks to finish with a hard push of car washes, etc. to meet our goal of covering all of the hotel cost.
Hard work yes, but it certainly takes a huge bite out of the financial issues. We also had to make the choice between Midland, TX and Salem, VA. With the cost associated with gas, we have elected to go to Salem, VA.
