San Francisco Giants catcher Buster Posey, along with his wife Kristen, announced a joint philanthropic effort with Esurance called &#8220;Quotes for a Cure&#8221; to raise awareness and money for pediatric cancer. Throughout August, each time someone completes an auto insurance quote with Esurance by visiting www.esurance.com/QuotesForACure, the company will donate $10 to the Buster and Kristen Posey Fund with a goal to raise $150,000.
