New York ? An ex-girlfriend of Roberto Alomar filed an explosive lawsuit alleging the former baseball standout insisted on unprotected sex for four years despite having AIDS.

The lawsuit, filed Jan. 30 and transferred to U.S. District Court on Wednesday, 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, who was once engaged to tennis player Mary Pierce, spent 17 years in the majors.
