Alex loves school, art and reading. His favorite books are the Magic Tree House Books.
However, he was born with posterior urethral valves (PUV), a disease that affects his kidneys. The disease develops when extra flaps of tissue grow in the urethra, before birth.
Alex spent the first three weeks of his life in the hospital having his ureters, the tubes connecting the kidney and bladder, removed.
At 3 1/2 years old he had his bladder augmented to be larger. He will most likely need a kidney transplant around his 10th or 11th birthday.
"This is Mr. Alex Murray. Our new baseball teammate," said head coach Todd Asalon to the media.
"It almost made me cry. I was fighting back the tears. He was just so happy out there and smiling. When he comes out here and plays with them, he's just so happy and feels so accepted and loves that the team wants him to be a part of them, that they came and asked him to be a part of the team," said Gina Murray, Alex's mom.
After the signing, Alex joined the team for their annual Halloween game.
Alex's long-term goal is to be an illustrator.
