D.C. United employs three of MLS’s 24 highest-paid players in base salary, according to documents released by the players’ union Friday.

Canadian midfielder-forward Dwayne De Rosario, the 2011 MLS most valuable player, is 10th at $617,857. His total compensation, factoring in bonuses and guarantees, is an estimated $663,190.

Last year De Rosario received $425,000 in base salary and $494,000 overall. During the winter, with De Rosario scheduled to enter the final season of his contract, the sides negotiated a new, multiyear deal.

Monte­negro midfielder Branko Boskovic, a part-time starter since recovering from major knee surgery last year, is 16th on the base list at $409,000 ($545,000 overall). Boskovic’s contract expires in July. It’s unclear whether United will try to retain him at a lower figure, offer the same salary or release him.

Albanian striker Hamdi Salihi, an offseason signing who has scored in four of the past five matches after a poor start, is 24th at $305,000. However, he will receive an additional $182,000 in bonuses and guarantees for a $487,000 total.

Brazilian striker Maicon Santos, United’s top scorer with six goals, is making $106,000 ($114,000 overall). The club’s highest-paid American is defender Brandon McDonald at $220,000 ($258,000).

New York Red Bulls forward Thierry Henry is MLS’s top earner at $5 million in base salary and $5.6 million overall. Teammate Rafael Marquez is second at $4.6 million in both categories, followed by the Los Angeles Galaxy’s David Beckham ($3 million/$4 million), Robbie Keane ($2.9 million/$3.4 million) and Landon Donovan ($2.4 million in both lists.

The Galaxy, 2011 MLS Cup champions, is last in the Western Conference with a 3-7-2 record. Toronto FC, winless in league play, is responsible for three of the top nine salaries in MLS.

United’s best bargains? Left back Daniel Woolard, who is enjoying an outstanding season, at $56,250 in both categories; top-choice goalkeeper Bill Hamid at $70,000/$84,750; and midfielder Nick DeLeon, a rookie of the year candidate, at $44,000/$79,000.
