Marin County HR Contest Participant Sponsor Sheet



Each school selects a team of 5 participants (maximum of 2 coaches).

ALL players collect sponsors from either individuals or local business (download Sponsorship Forma above). Sponsors can donate a flat amount, an amount per HR hit by an individual, or HR hit per team.

Each participant (team) brings their sponsorship forms to the event and hits homeruns until they reach 10 outs. An out counts as any hit that does not go over the designated fence and is not counted as a homerun. The field is staffed with volunteers for check-in and check-out, as well as score keeper to record the number of home runs hit by each participant. 

After the event, participants go back to their sponsors and let them know the number go HRs hit. Sponsors make donations on-line through this website in the "Donate or Participate" section.  When making their donation, there is a form for sponsors to include the name of the participant they sponsored. 100% of all proceeds for this event will go UCSF Breast Cancer Research Center. 

Prizes will be awarded to the individual player and team that raises the most most donations.

Prizes will also be awarded to the team that wins the contest (most HRs combined).

When it is your turn, line up on the side of the fence and wait until it is your turn to hit.

You hit until you have gotten a total of 10 outs.

When you have gotten 9 outs, there will be a pink baseball introduced! If you hit a pink ball for a home run, you collect double money from your sponsors for that home run. You continue to hit with pink balls until you have reached your 10th out. When reached, you are done.

When you are finished your turn, receive a stamp that validates your participation and to collect a sponsorship sheet if you do not already have one.

Visit your sponsors after the event and tell them how many home runs you hit. Your sponsors can go online to this website and donate their amount under your name.
