The Dodgers are expected to annonce today that they have signed two-year player-development agreements with two new minor-league affiliates. At the Triple-A level, the club is switching its affiliation from Las Vegas, where it has been for the past eight seasons, back to Albuquerque, N.M., where it was continuously from 1972-2000. At the Double-A level, the Dodgers are moving from Jacksonville, Fla,, to another unnamed Southern League market, believed to be Chattanooga, Tenn., which has been affiliated with the Cincinnati Reds for the past 21 seasons. Most of the Dodgers’ other minor-league affiliations — high Single-A Inland Empire (San Bernardino) of the California League, low Single-A Great Lakes (Midland, Mich.) of the Midwest League and Rookie-level Odgen, Utah, of the Pioneer League — are expected to stay the same. Because they are moving their spring-training operations from Vero Beach, Fla., to Glendale, Ariz., the Dodgers’ other Rookie-level affiliate will be moved from the Gulf Coast League to the Arizona League
