Baseball investigators told a state judge Thursday they have extensive evidence that Cincinnati Reds manager Pete Rose bet on his team's games.

Special investigator John M. Dowd said the substantial evidence includes telephone records, signed checks and betting sheets in Rose's handwriting.

Dowd was baseball's only witness Thursday during a day-long hearing before Nadel, who will decide whether to give Rose a temporary restraining order blocking the hearing with Giamatti. Thursday's hearing was recessed in late afternoon before Dowd could be cross-examined by Rose's lawyers.
