A brave 11-year-old girl fought off a man who tried to grab her as she watched a US Open practice match with her family at the National Tennis Center in Queens on Saturday afternoon, police said.

The abduction attempt took place at around 3:45 p.m. when the man snuck up behind the girl, grabbed her wrist, and warned her he’d kill her if she didn’t come with him.

She tore her hand free and kicked the man — who fled into the crowd.

He is in his late 20s or early 30s with short dark hair and a soul patch on his chin. He wore a red and white striped shirt, khaki shorts, and sunglasses. He has a tattoo with words on his right wrist.
