Liam Castellanos, the son of Phillies slugger Nick Castellanos, has become a favorite face at Citizens Bank Park whenever he comes to support his dad.

Phillies fans are loving the special bond between father and son. What is even more special though is how Liam uses his celebrity to give back to those who need it the most.

He first debuted a t-shirt design which benefited a charity while his dad played for the Cincinnati Reds.

Now, he is doing it again.

This time it’s a Philly t-shirt called “Battle Cry” that is being released in conjunction with In The Clutch.

The shirt features a hand-drawn portrait of Liam wearing a bandana with illustrations of his dad and other Phillies players on it.

Liam selected Kisses for Kyle, a Willow Grove-based non-profit that helps kids and families battling pediatric cancer, to benefit from the sales of the new shirt.

Sharon Snyder started the foundation in honor of her son Kyle who was diagnosed with leukemia just before his second birthday and lost his battle against cancer months later.

The Snyder family loves baseball especially their hometown team. Even Kyle at his young age loved the game too.

All this makes the donations from Liam’s t-shirt even more poignant.
