[MLS IMPORTS WATCH] MLS clubs rely heavily on importing players when they make offseason moves.
So far, 51 foreigners with no previous experience in U.S. leagues or the college ranks have been used by MLS clubs in 2012.
Several have been key contributors in the success of their respective clubs -- South Korean Young-Pyo Lee and Argentine Martin Bonjour at 4-2-2 Vancouver, Austria keeper Michael Gspurning at 4-1-1 Seattle and Panamanian Blas Perez (three goals and three assists for FC Dallas) come to mind -- but many have had little impact.
Lee, Gspurning and Perez are among eight imports who have played every minute. Besides Lee and Gspurning, the only one of them who plays on a team with a winning record is the much-maligned Swede Markus Holgersson at 4-3-1 New York.
One team that has hit the mark with its offseason signings: Colorado, where Colombians Luis Zapata and Jaime Castrillon and Argentine Martin Rivero have all been starting regularly and contributing.
Probably the biggest bust is Albanian Hamdi Salihi. He's has been no factor in D.C. United's success despite his Designated Player salary.
San Jose is this season's other surprise, but it has not been starting any of its three imports recently. Honduran Victor Bernandez was very good before being injured, while Colombian veteran Tressor Moreno has only been used sparingly.
The two clubs who have imported the most players are New England and Philadelphia. Of the Revs' six imports, only Frenchman Saer Sene has been starting. Panamanian Gabriel Gomezand Colombian Lionard Pajoy have combined for four of the Union's five goals, but Costa Ricans Porfirio Lopez and Josue Martinez have been disappointments.
