CHULA VISTA, CALIF., DEC. 1 -- San Francisco Giants outfielder Kevin Mitchell, the 1989 National League MVP, was free on bail today after being arrested for investigation of raping an acquaintance at his home, authorities said.

Mitchell posted $61,000 bail late Saturday night after being booked for investigation of rape, battery and false imprisonment, authorities said.

The rape was alleged to have taken place 4 a.m. PST Saturday. Mitchell, 30, was arrested at 5:30 p.m., and he posted bail about five hours later.

"The victim, an acquaintance of Mitchell's, went to his residence at his request to talk," detective Tom Everett's report said. "He dragged her into his bedroom where he forcibly raped her."

Mitchell also was under investigation for rape with a foreign object, three counts of battery and a count of false imprisonment, said Lt. Art Gawf.

Following his MVP season, Mitchell signed a four-year, $15 million contract with the Giants. The deal gave him a $1 million signing bonus and $3.5 million a season from 1991 to 1994.

In September, a house guest of Mitchell's was arrested in connection with the 1988 slaying of a San Diego police officer who was chasing gang members.

San Diego police learned that one of the alleged gang members, Kyle Patrick Winters, 27, was staying at Mitchell's Foster City, Calif., home.

San Francisco police arrested Winters after he dropped Mitchell off at Candlestick Park, left and then returned to the stadium for a game.

Murder charges have been filed against six alleged gang members, including Winters.
