Part owner of the Yankees, Orin Wilf, is splitting from his wife Lisa after living separately for over a year. Lisa alleges that Orin, a real estate developer gambled away up to $20 million of their fortune in the Bahamas and Atlantic City over the 12 years they were married. A source close to Orin confirms that he used to have a gambling habit, but sought treatment and has been free of the addiction for over two years. The couple has two sons, and lived in Manhattan. Their main source of conflict is over money. Wilf comes from a family of sports dynasties, with relatives who also own the Minnesota Vikings. His company, Skyline Developers is currently working on a stone and glass building at 200 East 79th st. Lisa’s lawyer did not release a statement in the matter. Calls to Orin’s offices were not returned, and his lawyer Laurence P. Greenburg has not commented regarding the divorce.
