"We are extremely proud of what DeAndre has accomplished in his young professional career," said Sounders co-owner and general manager Adrian Hanauer in a statement. "His success is a reflection of his individual ability as well as soccer development in Washington State and the continued commitment to progress the sport in this country. DeAndre is and always will be a special member of the Sounders FC family, and we are excited to have him in Seattle for the remainder of the season."
Yedlin, 21, was the Sounders'
first Homegrown Player signing in January 2013 and became the first MLS Homegrown Player to play in the World Cup for the USA, making three appearances at Brazil 2014.
Yedlin's transfer is one of the quickest for an American to have entered MLS. Michael Bradley played just one full season with the New York MetroStars (30 games) before being transferred to Dutch club Heerenveen in 2006. Jozy Altidore played parts of three seasons and 37 games for New York before joining Spain's Villarreal in 2008.
Like Yedlin, Maurice Edu was transferred midway through his second MLS season, from Toronto FC to Rangers in 2008, but after just 38 games. Tim Ream moved from the New York Red Bulls to Bolton Wanderers after two full seasons in 2012.
Yedlin was born in Seattle and grew up in Shoreline where he played youth soccer for Emerald City, Northwest Nationals and Crossfire. He attended O'Dea High School and was a member of the inaugural Sounders FC Academy class. He played two seasons at Akron under Caleb Porter before signing with the Sounders.
