Four years ago in South Africa, only six of the more than 700 players playing at the World Cup plied their trade at the club level in MLS. Four of those players played for the US, with Andrew Boyens playing for New Zealand and Roger Espinoza playing for Honduras.
That total was the lowest in league history; 15 MLSers were named to World Cup rosters in 2006 (11 for the US), 11 in 2002 (all for the US), and 19 in 1998 (16 for the US).
In Brazil, there will be a significant increase from 2010, and MLS might even set a new high for its participation in the World Cup. A total of 31 players (15 US, 16 international) -- a record for MLS -- were either named as part of a 23-man roster heading to the World Cup or on the provisional list in case someone gets injured. The full list is below.
