A Brooklyn girl who claims her high-school softball coach told her to "take it like a man" when she injured a finger during practice now wants to hit the city where it hurts — in the wallet.

Lincoln High School junior Rebecca Sacerio, 16, of Coney Island, is suing the Department of Education for $5 million.

She claims to have suffered permanent damage while taking part in the five-hour session with a right index finger broken in three places.

"I told her it looked swollen and had a funny color," Rebecca recalled of the May 2, 2009, incident. "[Coach Sari Schoen feld] told me her hand always looked like that when she played."

Rebecca, who plays third base, said that the coach had been hitting line drives to her and her teammates and that one smashed into the finger on her throwing hand.

But when she told Schoenfeld, the coach allegedly told her to "take it like a man!"

And when another liner hit the same finger, she again was told to tough it out.

Her mother, Paula, applied ice and gave her Tylenol, but two days passed with no improvement. Finally, a specialist told her she needed surgery.

Rebecca underwent three hand operations, and vertical and horizontal rods were implanted in the finger and kept there for five weeks. They have since been removed.

But she contracted a post-surgery infection, now has arthritis in that finger, and has had to learn to write using her middle finger because her index finger is "useless."

All of which could have been avoided, the suit says, if her coach had applied first aid instead of tough love.

A department spokesman declined to comment.

Schoenfeld, reached on her cell phone, said only, "No comment."
