The LA Galaxy forward is one of eight MLS players earning seven figures, according to the salary list published by the MLS Players' Union.
Robbie Keane's $4 million base salary is tops in the league, supplanting the New York Red Bulls forward from that distinction, according to figures released by the MLS Players' Union on Monday.
Henry's $3.75 million base salary is down from $5 million a season ago, but his guaranteed compensation, which takes into account guaranteed bonuses annualized over the course of a player's contract, is a league-high $4.35 million. Keane's guaranteed compensation is a shade less at $4,333,333.33.
The international stars are two of eight players in the league making seven figures in base salary. The others are Henry's teammate Tim Cahill ($3.5 million); Keane's teammate Landon Donovan ($2.5 million); Seattle Sounders new signing Obafemi Martins ($1.6 million); injured Toronto FC striker Danny Koevermans ($1.25 million); Vancouver Whitecaps forward Kenny Miller ($1,114,992) and Montreal Impact striker Marco Di Vaio ($1,000,008).
As for some of the U.S. internationals who have increased their pay substantially, Chris Wondolowski's Designated Player deal with San Jose has him earning a $550,000 salary this season (up from $300,000 in 2012); Chris Pontius' new deal has the D.C. winger earning $330,000 (up from $155,00 last season); Sporting KC center back Matt Besler nearly doubled his previous salary (up to $180,000 from $91,751) while teammate Graham Zusi is earning $140,000 (up from $105,000 a season ago).
