"We are honoring him today with Major League Baseball and the Yankees, commemorating Cancer Awareness Month," Yankees manager Joe Girardi said. "For children under the age of 15, pediatric cancer is the No. 1 killer. Over 250,000 children are diagnosed with cancer worldwide every year.
"Billy is extremely brave and has shown a lot of strength through this, so we are honoring him today and our hats are off to him."
Major League Baseball recently announced that it has launched a league-wide effort by dedicating a special Childhood Cancer Awareness Day at all of its ballparks. In partnership with Stand Up To Cancer, MLB has encouraged clubs to support this new initiative in commemoration of Childhood Cancer Awareness Month through a variety of special events.
All Major League players, coaches, umpires and grounds crew members have worn gold-ribbon decals and wristbands to further promote awareness for childhood cancer.
Billy and his family -- including his twin brother, Michael, and his older brother, Joey (11) -- made the trip to the Bronx on Friday from their home in Millstone, N.J.
The journey was a welcome perk for the pre-kindergarten student, who recently completed a 48-week chemotherapy program in response to the tumor's spread down his left optic pathway. Since being diagnosed, Billy has also been subjected to countless MRI examinations and doses of medication.
"Yet through all of this, Billy handles everything with bravery and strength," said his father, Vinny. "He has a smile that brings joy to everyone who meets him, and you cannot help but feel happy when you're around him. He truly is 'Brave' Billy."
