As the penalty hit the woodwork without Frei touching it, the rebound did not count in Portland.
Seattle star Ruidiaz then broke the deadlock with a penalty of his own just past the hour-mark, having been fouled by Timbers goalkeeper Jeff Attinella.

- Only one of the last eight teams to debut in MLS have won their inaugural match, dating back to Portland Timbers in 2011 (LAFC 1-0 Seattle in 2018). Orlando City and New York City drew against each other in both teams' inaugural match in 2015, while the other five teams that joined the league in that time lost their opening match.
- Of MLS' last nine new teams, only one have failed to score in their inaugural match in the competition. Montreal lost 2-0 to Vancouver Whitecaps in 2012.
- Of the 14 teams to play their inaugural MLS match on the road, only two have managed to win; including Los Angeles in 2018 (also Chicago Fire in 1998, at Miami Fusion). Two more managed draws while 10 of the 14 teams that started on the road lost their inaugural match.
- The last six MLS expansion clubs scored in their first away match in the league dating back to 2015. Five of the teams scored one goal while Atlanta United scored six against fellow newcomers Minnesota United in 2017.

- New Impact manager Henry took charge of Monaco in Ligue 1 last season between October 2018 and January 2019.

Atlanta are eighth and outside the play-off spots – level on points with seventh-placed Philadelphia Union, who have played two games less.
Elsewhere, Orlando City catapulted themselves up to third in the Eastern Conference after Daryl Dike's 97th-minute goal snatched a 2-1 win over DC United, the Red Bulls edged FC Cincinnati 1-0, Austin defeated Real Salt Lake 2-1 and Dallas played out a 0-0 draw with 10-man Minnesota United.
The Revs' four-match unbeaten streak in MLS was ended by a 5-1 thrashing at the hands of Columbus Crew at the weekend.
Their recent run has lifted them off the foot of the Eastern Conference and kept them in the hunt for what looked to be an unlikely playoff place.
Porter is confident his team can quickly put the weekend's disappointment behind them.
"You can't lose to teams that are in around you and give them points," Porter said. "They are in the hunt with us for the playoffs, so it's really important we bounce back.
"We still have confidence. We know we're a good team, and it has to be the next game. This next game against Atlanta is vitally important for us to get three points. We are really hungry to make the playoffs. It was not a great start to the year, and we're really looking to fix that.
"I reminded the guys that we won four in a row. We're playing really well, and we can't forget about that. But we do need to use this last game as a little bit of a wake-up call and to continue to remind ourselves that we have to keep improving."
Meanwhile, Atlanta are on a five-game unbeaten streak of their own after a 2-1 win over Toronto FC.
They sit five places and five points above New England, and they will be aiming to extend their run to keep the pressure on the teams above them.

MATCH PREDICTION: NEW ENGLAND REVOLUTION WIN
New England's six-match unbeaten run against Atlanta ended with a 4-1 road loss on March 9. The Revs have won three straight home matches against Atlanta after not winning any of the first three meetings in Foxborough (D2 L1).
