Flynn McGuire, a 10-year-old Cubs fan from Yorkville, Ill., who underwent a craniotomy to have a brain tumor removed at the age of 1, enjoyed a memorable afternoon Friday at Wrigley Field. Flynn served as Advocate Health Care’s Honorary Cubs Bat Kid this afternoon as the Cubs took on the Miami Marlins. Flynn, who was accompanied by his father, Dan, mother, Emma and sister, Hazel, sat in the dugout and enjoyed batting practice before the game, receive a customized jersey, a baseball for players to sign and was featured on the video board and Marquee Sports Network during the game. “This was pretty special,” said Flynn’s father, Dan. “For Advocate and the Cubs to have us out here like this and to see that other people are appreciative of what Flynn has been through. It really puts into perspective how lucky we really are. “Flynn is a shy kid, doesn’t really like the spotlight on him. But today I think is another one of those realizations for him about how lucky he is, not only to be alive today, but to be here today experiencing all this.” The highlight of Flynn’s day was getting to meet his favorite player, Nico Hoerner, and also getting his autograph. “That was really cool,” said Flynn with a big smile. On September 25, 2013, Flynn, who had just celebrated his first birthday the day before, suffered a seizure and become pale and unresponsive. After being rushed to Advocate Children’s Hospital he was diagnosed with obstructive hydrocephalus, which is fluid buildup in the brain. He had a large brain tumor and needed a craniotomy and resection. He is doing well today and comes in for surveillance imaging.
