Sports is not a cheap field. A good amount of money is required to carry out all the events and additional activities. 

For the entire set to work, multiple sponsorships are required by the committee or the team. This selection depends upon what is the purpose and end goal of the funding. 

Chicago Cubs is a baseball team. It is part of the MLB and required its own set of sponsors to fund the multiple ventures that they have in mind. 

For this, they get in touch with the local businesses first. There are multiple reasons behind doing so. 

First, it is easy to get local support. People love them and they want them to win games. 

This not only helps the team but also helps in supporting the local business on a national and international level. 

In exchange for sponsorship, marketing and publicity are asked by the owner as they can grow their business and popularity. 

If the partnership is successful, then the support is also maintained by the sponsor. In the long run, it is useful for both parties.
