Dave Roberts has returned to the Padres, where he serves as the team's first base coach, after battling cancer. He learned less than a year ago that he had Hodgkin's lymphoma at age 37. Roberts has been showing up at Petco Park over the past month to instruct a few players on base-running skills. "The thing that I probably gained the most is I never realized how many people -- aside from the fact of being appreciative and when people say 'You don't know what you have until it can potentially be taken from you' -- cared for me and loved me, from family to friends to fans," Roberts said. "The e-mails, the cards, all the well wishes, were amazing. I never really had anyone constantly praying for me and my well being. To feel that wherever I went, from San Francisco to San Diego to Boston and to outside the country, was very humbling."
