Barrett has been invited to attend an important baseball camp over the summer, but his mother, who works two jobs to support the family, tells him that they simply don't have the money to send him. Barrett is devastated, but he won't give up on his dream and decides to start mowing lawns to earn the money himself. He goes to the Mitchells' house first and knocks on the door. His teammate Kai answers, and he is not happy to see Barrett. Kai plays ball on Barrett's team, but he has not been invited to the summer camp and is still upset. Barrett wishes Kai's sister, Charise, or his father had answered the door. At least they would be reasonable. Barrett presses on anyway and offers his lawn-mowing services to Kai. Kai snickers and says they don't need their lawn cut. Barrett looks at the Mitchells' overgrown front lawn and knows Kai is lying, but he shrugs his shoulders and leaves to visit the next house. There are plenty of houses on his street; he'll earn that money somehow.
