NEW YORK (FOX 5 NEWS) - Nayyeyln and Victor Garcia, of the Dominican Republic, share more than just the same parents. In October, Nayyeyln, 7, donated bone marrow to her older brother. Victor, 11, was diagnosed with a rare form of leukemia in 2015, a dire diagnosis without known causes or effective forms of simple treatment. In short, he needed a bone marrow transplant to survive.
"I just saved my brother's life because I didn't want him to die," Nayyeyln said.
Thanks to the Icla da Silva Foundation, the family learned Nayyelyn was a 100 percent match. The likelihood of that happening is just 30 percent. The procedure was in October. Today the kids are happy and healthy.
"I love her very much and I am grateful she saved my life," Victor said in Spanish.
To honor the siblings' bond and bravery, the New York Yankees took the kids out for a day to remember. The best part was a private tour of the Bronx Zoo with the Bronx Bombers, including Didi Georgious and Dellin Betances. This event kicked off the Yankees' annual HOPE Week, a chance to take the attention off the players and place it on some smaller heroes.
"They're fun to talk to," Georgious said. "She was singing in the bus the whole ride, which is actually fun."
"Two awesome people, two brave people and for me, just glad to be part of this today," Betances said.
The kids are staying the night and going to the Yankees game Monday evening. They head back to Connecticut Tuesday for further treatment at the Yale Medical Center. They both said they'll remember this day as the best day of their hopefully very long lives.
