Kyle Schwarber

Kyle Schwarber is an MLB superhero. But during the offseason, he is a sidekick.

On Sunday, Schwarber hung out with 10-year-old Campbell Faulkner, who Schwarber met in Spring Training. At a party organized by HopeKids Arizona, Faulkner, who battles a rare form of a mitochondrial disease, served as Batman for the night. With Robin -- Schwarber -- by his side, Faulkner drove the Batmobile to the Bat Cave.

Schwarber and Faulkner emailed throughout the season. Faulkner even had his own solution to Schwarber's knee injury -- tears of the ACL and LCL -- which Schwarber suffered in the second game of the season.

"He said he wanted me to come to Phoenix so his doctors could help me," Schwarber says. "The cool part is he sent me an email right away after I got hurt when he got the news that my season was over.

"I remember when I was a kid, I wanted someone to look up to when I was his age. It's funny -- it's not like we look up to each other now. We're just friends. I think that's the best way to put it."

Of course, Schwarber did his best Dark Knight impression to come back from injury. Despite being deemed out for the season in April, the 23-year-old made it back for the World Series, hitting .412 during the Cubs' run to their first title in 116 years.
