The son of former New York City mayor Rudy Giuliani is suing Duke University, claiming his golf coach manufactured accusations against him to justify kicking him off the team to whittle the squad.

Andrew Giuliani, a 22-year-old rising senior, contends he had dreams of becoming a professional golfer and was dismissed without cause from the golf team in February without a chance to defend himself. He said in a statement Thursday that he sued "to make sure this doesn't happen to anyone else at Duke."

Giuliani was dismissed because coach O.D. Vincent III wanted to cut the team from 13 players to about half its size, the lawsuit said. He claims a breach of contract because he was recruited by Duke's previous coaching staff.

"This has been heartbreaking," Giuliani's mother, Donna Hanover, said in a statement. "We tried for many months to convince members of the Duke administration that this situation should be corrected and we are sad that we have now had to turn to the court."

The coach said Giuliani "flipped his putter a few feet to his golf bag" and drove fast while leaving a golf course parking lot, according to the lawsuit. Giuliani also was accused of playing a team football game harder than the other players liked and of being disrespectful to a trainer.
