This Sponsorship helps fund the stringing of rackets. Parker breaks strings every 3-6 days and more during tournaments. Each tournament he must put fresh strings on his four tennis rackets and will normally break strings on most of them. You can add as many string replacements to the cart as you would like to sponsor. We have created huge savings in this area as we purchased a stringing machine and Parker learned how to string his own rackets. This support covers the cost of the strings only.
