Porter is nearing the end of his fourth season in charge of the Timbers. Over his first three seasons, the Timbers lost the fewest games (25) of any MLS team and compiled regular-season point totals of 57 (2013), 49 (2014) and 53 (2015).

5. Portland’s record at Dick’s Sporting Goods Park is 1-4-3, though the Colorado Rapids have not beaten them at home in their last three attempts.

6.. The Rapids have not beaten Portland since March 22, 2014, which was their last win against the Timbers in Commerce City. Colorado is 0-3-2 in the most recent five meetings.

7. In all, the Rapids are 5-6-3 versus the Timbers. Four of the Rapids’ five wins came in the first five matchups between the two teams. With head coach Caleb Porter atthe helm, Portland has lost just one of the last nine against the Rapids.

8. The Timbers have added to their numbers since playing out a goalless draw against the Rapids at Dick’s Sporting Goods Park on July 4, in what was Tim Howard’s debut. They have acquired former Newcastle United defender Steven Taylor, and Lithuania international defender Vytautas Andriuškevičius. Taylor has filled the central defensive spot vacated by former Rapids defender Nat Borchers. Borchers is out for the season, having suffered an Achilles injury on July 23.

9. Portland goalkeeper Jake Gleeson is having his best season. He went almost exactly five years in between MLS regular season appearances. He started versus FC Dallas on April 17, 2011, and his next game was not until April 16 this year,
