The 63-year-old Stoneman became the Angels' GM in November 1999 and helped build the team into a perennial contender.

"I am looking forward now to the opportunity to continue to serve the club as an adviser, and also to be able to take a week off here or there and relax," Stoneman said in a statement.

After making the playoffs only three times previously, the Angels advanced to the postseason four times after Stoneman came in. They won their only World Series championship in 2002.

Los Angeles won the division this season for the third time in four years but was swept in by Boston in the first round.

Among Stoneman's significant moves was hiring the relatively inexperienced Mike Scioscia as manager before the 2000 season, signing pitcher Bartolo Colon in December 2003 and slugger Vladimir Guerrero in January 2004.

Guerrero was the league MVP in 2004, and Colon won the Cy Young Award in 2005. Stonemen drew some criticism over the past several seasons for his inability to land a power hitter to protect Guerrero in the lineup.

Stoneman pitched for eight years in the majors, compiling a 54-85 record and 4.08 ERA and pitching two no-hitters in stints with the Chicago Cubs, Montreal Expos, and the Angels. He retired in 1974.

Reagins, who joined the Angels as an intern in 1992, did not play pro ball. The 40-year-old has been player development director for six years.
