Baseball great Pete Rose (search) is back in trouble with the Internal Revenue Service (search), which says he owes nearly $1 million in unpaid taxes.

A federal tax lien alleges that baseball's all-time hits king owes $973,693.28 in taxes for the years 1997 to 2002. The IRS did not immediately return calls Friday seeking comment.

Rose, 63, spent five months in prison in 1990 and 1991 for filing false tax returns.

Rose's business manager, Warren Greene, said the lien filed Tuesday was "a private matter with Pete and his family" nd declined further comment.

Rose agreed to a lifetime ban from baseball in 1989 following an investigation that he bet on games. After 14 years of denial, he admitted in his recent book, "My Prison Without Bars" that he bet on games involving the Cincinnati Reds (search) while managing the team in the late 1980s.

Rose has said he hopes to be reinstated by commissioner Bud Selig, become eligible for the Hall of Fame ballot and work in the major leagues again.

The commissioner's office had no comment on the lien, spokesman Pat Courtney said. Bob DuPuy, baseball's chief operating officer, was not in the office Friday and could not be reached for comment.

During a 24-year career that included stints with the Reds, the Philadelphia Phillies and the Montreal Expos, Rose had a record 4,256 hits before retiring in 1986.

A fan favorite who was nicknamed "Charlie Hustle" because of his style of play, Rose made the All-Star team 17 times. He was the National League's rookie of the year in 1963, the Most Valuable Player in 1973 and MVP of the 1975 World Series. He led the league in hitting three times and played on three World Series champions.
