It was the Reds' second win of the season and it was a much-needed one as it placed them six points clear of bottom-placed DC United on the Eastern Conference table.
"Absolutely happy with the effort, I thought the whole group worked real hard today," Preki said. "I thought first half we were pretty decent and at the moment I can see the best football we've had so far this year. I think that we want to do that every day in training and every game if we can.
"Obviously second half I wasn't really happy the way we started the second half, we gave Seattle a chance and Stefan (Frei) made two important saves for us to keep us in. Dwayne (De Roasrio) makes a good play on a goal and after we get a second on a good breakaway and at times in the second half we played some good football."
Goalkeeper Frei said that the team was beginning to settle a bit better now, especially in the back half.
"Yeah, it's getting a little bit better I couldn't really help them much today with my voice but I feel we're organized pretty well," he said. "The first half they picked the holes between our guys to make their runs in and I think the guys are communicating better. I think one thing that has changed that is great is that their air balls that they're getting - everything that they throw at us I think we're getting it and putting it away so it's not laying in front of our goal and that helps a lot."
