The Fire (1-1-1) suffered their first loss of the season, while the Sounders (1-2-2) garnered their first win of the season. Chicago falls to 0-3-2 all-time against Seattle.
Trailing by a goal in the second half, the Fire had three big scoring chances in a 9-minute stretch from the 58th to 66th minutes, but Keller posted three of his game-high four saves to maintain Seattle's lead.
In the 58th, Fire midfielder Marco Pappa took a free kick that hit the Sounders' wall and was not cleared properly. Chicago forward Diego Chaves, who had scored his team-leading third goal earlier in the match, took a strike toward the near right post. But Keller dove to his left and got his left glove on the ball.
In the 61st, Puerari created an opening, but Keller came through with a foot save. And in the 66th, Pappa struck the ball with his cleats and tried to direct the ball to the right side of the frame, but Keller reacted quickly and pounced on the ball.
