"Will is dangerous in the box and always plays hard," said Sounders FC Sporting Director Chris Henderson in a PRess release. "He can score with both feet and with his head. He provides us with depth at forward and we are excited to have him in Seattle."
Bates appeared in 77 matches over four seasons at Virginia, tallying 46 goals with 10 assists. He was selected by the Sounders with the fifth overall selection in the 2013 MLS Supplemental Draft
