While many proclaim that MLS teams are pumped up when they come here to play to the Clink crowd such that it nullifies our home advantage, the numbers don't bear that out. For the Sounders MLS history from '09, roughly, the home win rate is 53%, loss rate is 29%, and draws are 19%. On the road, wins are 43%, losses are 25%, draws are 32%. While the home crowd is slightly more likely to see a home loss, they are also more likely to see a home win. For reference, overall in the same period MLS teams win about 50% of their home games.
