Seattle Sounders have sold more than 52,000 tickets to this weekend's home meeting with Real Salt Lake.
The second-placed Sounders host top-of-the-table Real Salt Lake at CenturyLink Field and will bring in another massive crowd after seeing more than 67,000 show up for the August 25 clash with Cascadia rivals Portland Timbers.
Friday's match is expected to bring in even more ticket sales for the Sounders meaning the RSL fixture could sneak into their top five MLS attendances.
In addition, Seattle have won all 17 matches in front of a crowd of more than 50,000 suggesting first-placed RSL could be ripe for the picking.
