An ex-girlfriend of Roberto Alomar has filed an explosive lawsuit, alleging the former baseball star insisted on having unprotected sex with her for four years despite having AIDS. The lawsuit contains accusations that could not be corroborated but portray Alomar as someone who demanded sex without a condom despite showing obvious signs of HIV. Ilya Dall is seeking at least $15 million in punitive damages from the 41-year-old former infielder. Alomar spent 17 years in the majors and was one of the game's great second basemen. Calls seeking comment from lawyers for Alomar and Dall were not immediately returned. Alomar lawyer Charles Bach told the New York Daily News the allegations are "frivolous and baseless."
