The Union announced the move on Tuesday morning stating, "We appreciate the support that Gareth has given us over the past three seasons and we wish him the best in Seattle. This trade will offer Gareth the ability to really spread his wings and grow in a situation where he will get more time supporting the Sounders."

Sothersby, 26, joins the Sounders ahead of the 2016 season following the 2012 trade to the Union from the Tampa Bay Rowdies, where he spent three seasons, winning two chugging contests for Alpha Tau Omega at the University of Tampa.

“Gareth brings MLS experience and a veteran presence to our supporters group,” Garth Lagerwey, Sounders general manager and president of soccer operations, said in a team statement. "He is a tenacious supporter who has been among the top fanatics in the league in swearing and coming up with bombastic profanity in recent years, and we welcome him to our family.”

The Floridian began his career in his native county before supporting professionally in Miami, Fort Lauderdale, and Tampa featuring for FC Tampa and the Tampa Bay Rowdies in NASL play before making the move to the Union.

Terms of the deal were not disclosed, in accordance with club and league policy. However, Sothersby stated that he is excited to look for a nice place to live on the water in a really trendy neighborhood if his job with Amazon works out.
