Ex-NY Yankees Champ: Locked Up & Broke ... All I've Got Is $39 and Noodles

Ex-NY Yankees outfielder Chad Curtis says he's broke as hell and can't afford a lawyer to fight a sexual assault lawsuit ... claiming all he has left is $39 and some prison noodles.

Curtis -- who won 2 World Series titles with the Yanks -- is currently doing 15 years for sexually assaulting 3 female students at a Michigan high school where he coached back in 2011.

Now, the women have followed up with a civil suit against Curtis -- but the 46-year-old says he's so broke, he can't even afford a lawyer to defend himself.

"I have $39 in my personal account," Curtis told a federal judge Monday ... "The state of Michigan has taken everything I own."

He added that his personal estate is limited to the "nine noodles in my cell."

According to Mlive.com, Curtis told the judge the accusers are lying -- and says, "I know the truth is on my side. I do not believe there will be a large verdict."
