Zachary Randolph’s heart is even bigger than his height.

The Memphis Grizzlies power forward literally gave a fan the shirt of his back this week.

Z-Bo saw a young boy with special needs cheering him on while he was sitting on the bench during Wednesday’s game.

“I heard Will (the boy) hollering … Z-Bo, Z-Bo … I just gave him the shirt,” Randolph told Fox & Friends on Sunday Morning. “I was surprised the camera caught it.”

Why did he do it? “I’ve been blessed,” he said. “it’s a blessing for me to have a friend and fan like Will.”

Morgan Furlong, Will’s father, said his son is thrilled.

“It was real special for (Will),” Furlong said.  “ He had the shirt on afterwards and was dancing in the hallways.”
