Signing autographs for 20 minutes before the game on Saturday? Just part of the responsibility of being a young Chicago Cubs leader, according to Anthony Rizzo.

“Putting on this jersey with the nationwide fanfare we have is a big responsibility no matter who you are,” Rizzo said. “I am aware I represent the Ricketts family, our front office and the terrific fan base every time I am out in public.”

Rizzo, Starlin Castro, Darwin Barney and Jeff Samardzija are the faces of the future for the rebuilding Cubs. The 24-year-old first baseman is entering his first full year in the major leagues with expectations of stardom.

“I believe that everything you work at and want in life is a great challenge,” he said. “I will respect the limits of my experience but that won’t stop me from trying to lead by example of my work. Being a good teammate and picking them up on and off the field is a simple goal of mine.”
