Chicago Cubs first baseman Anthony Rizzo has a big game coming up on Tuesday night as he takes the field in Game 3 of the NLCS, but before he arrived at Wrigley, he had another important stop to make.

Rizzo went over to Lurie Children’s Hospital on Tuesday afternoon to visit with patients and nurses, and brought lots of smiles to lots of faces in the process.

Here’s what Rizzo had to say on Twitter:

The Cubs also posted a couple of pictures of the visit:

Rizzo is extremely active in the battle against cancer, using the Anthony Rizzo Family Foundation to “raise money for cancer research and to provide support to children and their families battling the disease,” according to the foundation’s website. Rizzo himself is a cancer survivor, having battled Hodgkin’s lymphoma while a member of the Boston Red Sox organization in 2008.
