It was more of a leap, really, as the club clustered five goals over a 22 minute stretch on their way to a 5-1 win over the Atlanta Silverbacks.
That’s the most goals the three-time defending champions have scored in Open Cup competition.
The win sends Seattle through to the fourth round against the winner of the Portland Timbers-Cal FC match, still playing tonight.
The visiting Silverbacks showed up at Starfire Sports Stadium looking like a team that figured if it’s going to travel 2,500 miles across the country, it might as well try to win.
With the NASL club rejecting any thoughts of a cautious approach, the two teams were almost constantly dangerous throughout the first half.
Seattle’s Eddie Johnson had three good chances. Alex Caskey smoked one just over the crossbar. Osvaldo Alonso almost had a goal for the ages, which launched from across midfield when Atlanta goalkeeper Joe Nasco got caught far out of the penalty area after getting knocked down by one of his defenders.
The Silverbacks also had several chances in front of the Seattle goal.
However, nothing registered on the scoreboard until the 44th minute, when Jeff Parke chested the ball down to the foot of Andy Rose, who sizzled it into the back of the net.
Suddenly, those good chances that had missed in the first half started going in.
Two minutes into the second half, the Sounders struck again. This time Cordell Cato slipped a ball into the box, where Alonso knocked it in, low and to the far post.
Atlanta cut it to 2-1 in the 53rd minute, when Reinaldo Navia fired one past Bryan Meredith.
However, Caskey struck back a minute later, creating another two-goal cushion for Seattle.
Then Sammy Ochoa put it away with back-to-back goals in the 62nd and 66th minutes.
The convincing victory went against the early trend of this tournament, when seven of the 14 MLS teams that played Tuesday were eliminated by lower-level clubs.
Announced attendance was 3,703.After 80 minutes:
What we have here is basically a shooting range. Sounders still up, 5-1, but there is just a barrage on the Silverbacks keeper.
67th minute: Sorry, yall. They're coming too fast and furious. Now it's Sounders 5-1 with a pair of goals by Sammy Ochoa.
The five goals are the most the Sounders have ever scored in Open Cup competition.
54th minute: GOAL Seattle. This time Alex Caskey from the left side, inside the box.
53rd minute: GOAL Atlanta, credited to Reinaldo Navia from about 18 yards..
47th minute: GOAL Seattle. Alonso scores, assisted by Cato.
Second half: Has just kicked off. Sounders sent in David Estrada for Eddie Johnson.
Halftime: Sounders 1, Atlanta 0.
Shots 10-5 SEA; on goal 5-1 SEA; fouls 6-4 SEA; offside 3-1 ATL; corners 5-2 SEA.
44th minute: GOAL Seattle. Parke leaves ball for Rose who sizzles a rocket into back of the net from about 18 yards.
Through 40: Scoreless.
36th and 37th minutes: Chances by Alonso and Caskey. Alonso's shot from his own side of the pitch when Atlanta keeper came way out and got knocked down by his own defender. Keeper hustled back and got a hand on it.
Through 30 minutes: Still scoreless. Amazingly. Eddie Johnson has had chances for Seattle. And Sounders defense has looked wobbly enough for the Silverbacks to have had their share, too.
After 15 minutes: Scoreless. Cordell Cato active and impressive early.
First 10 minutes: Very attacking play by both sides. Good chances both ways, but more and better to Sounders.
Kickoff: Game has begun. Sounders in their super cyan kits. Silverbacks in red/black. (And yes, silver numbers on the back.)
Nice crowd. The seats look all sold. Also good representation in one end, but fewer on the berm than we've seen in the past.
Lineups: Sounders starters: GK Meredith; D Scott, Parke, Hurtado, Burch; M Cato, Alonso, Rose, Caskey; F Ochoa, Johnson. Reserves: Weber, Carrasco, Estrada, Evans, Levesque, Montero, Sivebaek.
For Atlanta: GK Nasco; D Moroney, Lancaster, Burciaga, Cox; M McManus, O'Brien, Turcois, Carr; F Horth, Navia. Reserves: Illyes, Paulini, Davis, Hunt, Colaluca, Ferreira, Santamaria.
Pregame: Greetings from Starfire Sports Stadium, where the crowd is filing in for tonight's U.S. Open Cup match between the Sounders and Atlanta Silverbacks.
Clearly the Sounders should be on alert after seeing seven of 14 MLS teams eliminated last night.The game is on neither TV nor radio, but will be webcast at SoundersFC.com.
The plan here is to keep this convention blog open, rather than a running one. I'll include updates before the game -- starting with lineups -- and update during the game, including all goals. I'll also try to stay active on Twitter @donruiztnt.
