PITTSBURGH (AP) _ Reputed gambling czar Anthony ''Tony'' Grosso, reported to be in ill health and ''tired of fighting,'' has pleaded guilty to 17 criminal counts in his second such plea in two days.

Grosso, 72 admitted Tuesday that he headed a multimillion-dollar numbers business in Allegheny County. He pleaded guilty Monday in U.S. District Court to 68 counts of operating an illegal numbers organization and tax evasion.

''You reach a certain age, you reach a certain health factor, you get tired of fighting,'' John Doherty, Grosso's attorney, said Tuesday.

Grosso, of suburban Mount Lebanon, has undergone a quintuple coronary bypass and suffered from colon cancer.

Prosecutor Lawrence Claus said Grosso faces a maximum of 100 years in jail and $185,000 in fines as a result of Tuesday's plea. He faces up to 340 years in prison and $8.2 million in fines on the federal counts.

Federal prosecutors estimated that Grosso's daily numbers operation grossed more than $13 million a year.
