Seattle Sounders FC certainly don't play like a first-year MLS soccer club.

Seattle kept its undefeated streak intact by spoiling Toronto FC's home debut with a 2-0 victory on Saturday at BMO Field.

Freddie Ljungberg and No. 1 overall pick Steve Zakuani provided the goals for Seattle, giving the expansion team its third consecutive victory to start the season.

Looking to make the playoffs for the first time in its three-year existence, Toronto received a rousing ovation from the sold-out crowd of 20,658 at the onset.

But the MLS club (1-1-1) couldn't capitalize on the momentum during a cold and extremely windy day that played havoc in Toronto.

"We're a team that likes to keep the ball on the ground but it was difficult against the wind and these conditions," Canadian midfielder Dwayne De Rosario told CBC Sports. "But saying that they managed to do it. We weren't able to pull out good chances.

"I'm very disappointed with the outcome and the performance."

Promising start

After a promising start by Toronto, Ljungberg gave Seattle a 1-0 lead on his first career MLS goal.

Ljungberg completed a beautiful give-and-go with Osvaldo Alonso before slipping the easy shot behind goalkeeper Greg Sutton.

Toronto failed to use the wind to its advantage in the first half despite buzzing around the net at various parts of the first 45 minutes.

It appeared De Rosario was going to pull Toronto FC even in the 40th minute, but Sebastien Le Toux made a sliding block just as the Canadian was about to pull the trigger. Seattle then scored in the final minute of the opening half on a play initiated by Ljungberg.

With the Toronto defence asleep in its own end, the ball bounced to Zakuani, who buried his first professional goal by Sutton.

Zakuani led the NCAA in goals and points in 2008, scoring 20 goals and adding seven assists for the Akron Zips in 23 games.

Glorious chances

Toronto had a pair of glorious chances to get its first home goal of the season. First, Amado Guevara's header went off the crossbar in the 68th minute, and then Pablo Vitti grazed the outside of the post in the 78th minute.

Seattle was able to protect its two-goal advantage, content to simply hold off Toronto in the second half.

De Rosario didn't have the dream homecoming he was hoping for on Saturday.

Toronto traded for De Rosario, who grew up in Toronto's east end, from the Houston Dynamo in the off-season with the expectation that the veteran forward would help the team make the playoffs.

While De Rosario, a big contributor during Toronto's first two road games, had his moments against Seattle, he couldn't generate any production where it counted most.

Free kick

De Rosario was awarded a free kick moments after Guevara's miss, but the shot was easily denied by Seattle goalie Kasey Keller, who earned his third consecutive shutout.

Still, De Rosario said he was thrilled to be playing in front of family and friends.

"It feels good to be here," he said.

Toronto players were also frustrated with the officiating, a feeling shared by irate fans showing their displeasure whenever an apparent takedown wasn't called.

Seattle played without star striker and MLS player of the week Fredy Montero, who is battling the flu, according the team.

However, a spokesman for the King County prosecutor's office in Seattle confirmed Friday they are reviewing a woman's allegations that Montero sexually assaulted her last month. No decision to move forward on the allegations has been made.

Toronto's next game is against FC Dallas at home on April 11 (CBC, CBCSports.ca, 3:30 p.m. ET).
