I was up at the Sounders-Whitecaps game in Bellingham (!) tonight, watching David Simon referee, so I missed all the MLS games. But it brought a question up: How do I find out who is refereeing each MLS or A-League game ahead of time? Is there a schedule, and if there is, how far in advance is it? Does anyone know?
http://www.ussoccer-data.com/schdmenu.htm This will only show you who referees from the past and for the day of the match. From what I found, you cannot find out in advance unless you are in the pool.
MLS Referees are listed in the preview report of each game....including a bunch of statistics for the CR. You should be able to find out this information sometime during the week preceeding the game. In the A-League, this information is not posted.
Seattle v. Vancouver is quite good. I remember driving from Portland to catch the match. I also enjoied the Portland v. Seattle matches as well. Had the pleasure of meeting some really nice referees after.
