Bailey stood at midfield with Seattle star Clint Dempsey at his side, waiting for kickoff against Tottenham.
When the whistle blew, the 18-year-old Bailey — a Make-A-Wish recipient from Greater Pennsylvania and West Virginia — took the pass from Dempsey, dribbled down the field and took a shot on former U.S. national team goalkeeper Brad Friedel. He was then subbed off in front of 55,349 to a massive ovation.
Bailey took part in training with the Sounders on Friday and the club made sure his experience was special.
Bailey walked out with the team during pregame ceremonies Saturday and was introduced as part of the starting lineup. Seattle's largest fan group — the Emerald City Supporters — created a small tifo in honor of Bailey, and green cards were handed out through the stadium with his name and his No. 45.
