The Pete Rose gambling inquiry has taken a big step to completion, with baseball Commissioner A. Barlett Giamatti receiving a report from the chief investigator.

Special counsel John M. Dowd personally delivered the report to Giamatti on Tuesday at the commissioner's office, according to a source familiar with the inquiry.In a two-paragraph statement, Giamatti said: "John Dowd, special counsel to the commissioner, has submitted his report to me regarding allegations concerning Mr. Pete Rose. Should any information relevant to the investigation be obtained, he will forward it to me.

"I will now study the report thoroughly."

One source, who spoke on the condition that he not be identified, said a hearing probably will be held after Rose's lawyers receive the report. One of Rose's lawyers said no hearing had yet been scheduled.

The commissioner's office has never acknowledged that the investigation centers around allegations that Rose bet on baseball. But sources familiar with the inquiry have confirmed that, and for seven weeks Rose has been the subject of almost daily allegations.

Rose has at times denied betting on baseball and at other times refused to answer that question.

If Giamatti determines Rose has bet on baseball, the Cincinnati manager would be suspended for one year. If Giamatti finds bets were placed on games involving the Reds, Rose would be banned for life.
