The hosts currently sit bottom of the Major League Soccer Western Conference, having only won three matches throughout the season.
Match preview
It has been a difficult season so far for the Earthquakes, having won just three matches the team currently sits bottom of the Western Conference with a lot of work to do for the remainder of the season.
One victory could change that though due to the fact they sit just three points behind Sporting Kansas City, but they will need to drastically improve their performances.
The Earthquakes have conceded nine goals in their last two matches, with no team letting in more throughout the entire season in the Western Conference.
It is an area for Luchi Gonzalez to work on moving forward, but they have been much stronger at home than on the road, which should give a little belief for this match.
The Earthquakes did take a 2-1 lead against FC Cincinnati during their last outing, but they were unable to hang onto that as they conceded three goals in the space of 10 minutes towards the end of the game.
Portland will look to take advantage of that in midweek, especially due to the positive run of form that the team have put together in recent weeks.
While they were held to a goalless draw against St Louis City, the Timbers are undefeated in their previous four matches which has put a lot of confidence together for them.
That has also allowed Portland to start climbing up the league table, with the club currently sitting in 10th place, with the recent consistency being exactly what they needed.
It is something Portland struggled with at the start of the season, but putting a run of results together has made a positive impact, and a win could move them into seventh this week.
While they have been slightly weaker on the road in this campaign, that is something they have been working on lately to change, which is why the team heads into this with lots of belief.
