These two teams start the weekend seventh and fifth in the Western Conference, so who will tighten their grip on a play-off berth.
Last season’s MLS Cup Finalists Portland Timbers appear to have found form at just the right time.
Giovanni Savarese’s team beat Atlanta United 2-1 last weekend, with both Santiago Moreno and Darion Asprilla making no mistake from 12 yards.
The Timbers have now converted ten penalties this season, the joint-second most in a single MLS season.
More importantly, this rounded out a perfect week for Portland, following victories over Seattle and Austin, both also by the same 2-1 scoreline.
So, they are just above the play-off line but, with their remaining games against fellow contenders Columbus, LAFC and RSL, every point counts.
Minnesota United meanwhile kick off two points and two places above their hosts, despite being battered 3-0 by FC Dallas last weekend.
Michael Boxall’s own goal opened the floodgates with Dallas scoring twice more in the subsequent 223 seconds, the fastest a team has ever scored a trio of goals in MLS history.
Franco Fragapane was also sent off in St. Paul, as the Loons suffered a second successive 3-0 defeat, also beaten in Utah the week before.
So, Adrian Heath’s team have work to do.
Who will claim a massive victory at Providence Park?
